Upcoming Events And Everything About Solar Flares - In My View

Upcoming Events And Everything About Solar Flares - In My View

As we all are familiar with the fact that, the sun is the only source of energy on which we are living. After all, we wouldn't be here without it. On one hand, the sun is the most vital source of energy for me, you, as well as all the living being on Planet Earth, and on the other hand, it also gives us a headache every once in a while. Astronomers had captured a glimpse of a Solar Flare a few days ago (As of 15 Feb 2018) producing a CME (coronal mass ejection), and it's expected to hit planet earth today as a solar storm.

On August 31, 2012, a long prominence/filament of solar material that had been hovering in the Sun's atmosphere, the corona, erupted out into space at 4:36 p.m. EDT. Seen here from the Solar Dynamics Observatory, the flare caused an aurora on Earth on September 3.

What Is Solar Flare?

A Solar Flare is a sudden flash of increased sun's brightness due to a large explosion of magnetic energy within the Sun's Atmosphere. The energy released during a solar flare is generally in the order of  1 × 1020 joules to 1 × 1025 joules.  A solar flare cannot be detected by naked eyes. In order to detect a solar flare, an observer needs to view it through a telescope or some other astronomical instruments. Sometimes solar flares are accompanied by Coronal Mass Ejection.

The amount of energy released during the occurrence of a solar flare is equivalent to the explosion of 100-megaton hydrogen bomb exploding at the same time or even 10 times greater than the energy released during the volcanic eruption. When a solar flare occurs in other than our sun's atmosphere is known as the stellar flare.



What Causes Solar Flare?

Frankly speaking, physicists are still baffled that what actually cause solar flare!!! The mechanism involved is still not well known. Therefore there is a general agreement on the facts related to The Source Of The Solar Flare's Energy. 

As per known theory, when charged particles (electrons) interact with the plasma, a solar flare is produced. Solar flares are believed to occur due to a process called magnetic reconnection. In simple terms, when the loop of magnetic force breaks apart and then rejoin; a vast amount of energy (solar flare) is released. Within a matter of minutes, particles are accelerated into Deep Space. The sudden breaking and then rejoining of the loop of magnetic force is the origin of the particle acceleration. Particles accelerated by the intense energy nearly to the speed of light.


How Often Do Solar Flares Occur?

Solar flares generally tend to occur near Sunspots - mostly in the active region. During the occurrence of a solar flare, all the layers of the sun (photosphere, chromosphere, and corona) are affected. Larger solar flares occur much less than the smaller solar flares.

Well, the frequency of occurrence of solar flare solely depends on the activity of the sun. In simple terms, in an 11-year solar cycle, their frequency varies from several flares per day when the sun is particularly active to the fewer than one flare per week when the sun is in a quiet phase.

Classification Of Solar Flares

An earlier method for The Classification Of Solar Flares was based on the intensity as well as the Emitting Surface of Hα line of the Solar Spectrum. But nowadays, the modern classification of solar flares are done according to the peak flux (W/m2) of X-rays from 100 to 800 picometre; as observed by the GOES (Geostationary Operation Environmental Satellite) spacecraft orbiting around the earth.

When Was The First Solar Flare Discovered?

The first ever recorded solar flare is also the most powerful flare ever recorded till date. Known as The Solar Storm Of 1859 occurred on Sept 1, 1859. It was independently reported by 2 British amateur astronomers Richard C. Carrington and Richard Hodgson. 

The solar storm of 1859, also known as the Carrington Event was visible to the naked eyes, produced Auroras all over around the world. At that time, physicist and scientist were unable to calculate the magnitude and strength of the solar flare of 1859. But today with modern techniques, scientist reconstructed the Carrington Event based on the Beryllium-10 isotopes produced during the solar storm of 1859.


How Do Solar Flares Effect Earth?


There are a variety of things that happen or effect earth due to solar flare; such as:
  1. Solar flare produces high energy particles and radiation which are quite dangerous for living organisms.
  2. Satellites orbiting around earth could be minorly damaged due to solar flares.
  3. There could be an increase in the visibility and as well as in the brightness of the Auroras; known as Southern or Northern lights.
  4. High-frequency radio waves could be severely degraded.
  5. Electrical Power Grids could be damaged severely due to solar flares.
  6. There will be an increase in the chances of sunburn or even cancer due to ultra-violet rays released during a solar flare.


How To Predict Solar Flares?

Still, nowadays physicists and scientists are unable to predict the upcoming solar flare with high accuracy because the current methods used by the scientist are too problematic. Although high sunspot activity is associated with an increased chance of solar flares production yet, there is no certain accurate indication that an active sunspot will definitely produce a solar flare. However, if a strong solar flare (M or X class) is predicted, the US National Oceanic and Atmospheric Administration (NOAA) directly issues a forecast/warning.

ON that note, I can say that I have tried enough to give an overview of Upcoming Events & Everything About Solar Flares - In My View within my reach. If there is any suggestion, I am all ears. Feel free to comment.

Why We Celebrate Maha Shivaratri - In My View

Why We Celebrate Maha Shivaratri - In My View

Aadi-Yogi-Mahadev

Maha Shivaratri is a Hindu festival celebrated especially in India and as well as in Nepal in the honor of The God Of Destruction - SHIVA. Shivaratri is generally observed by Hindus. This festival marks overcoming darkness and ignorance in life. Shivaratri is celebrated by simply remembering shiva, chanting prayers of Shiva, practicing yoga, fasting and contemplating ethics and virtues of honesty, restraint, and forgiveness.

When Shivaratri Is Celebrated?

Well, Shivaratri is celebrated every month (12 times ) according to Hindu Calendar, but Mahashivratri is observed once a year in late winter (February/march or PHALGUNA). The 13th night (waning crescent phase at night) /14th day (new moon phase during the day) of every lunar month is observed as a day of Shivaratri. Among all the twelve Shivaratri, Mahashivaratri is observed in February-march lunar month - which is also regarded as "The Great Night Of Shiva".

According to The Legend Of Mahadev, The Supreme One - there are so many distinct stories related to the celebration of Mahashivaratri such that


  1. Shivaratri is the day when the absolute formless god SADASHIVA appeared in the form of (Shankara) Kailashpati Shiva (One Of The Tridev).
  2. Shivaratri is the day when Lord Shiva was married to her better half DEVI PARVATI.
  3. Shivaratri is the day when The Supreme One "Lord Shiva" swallowed the deadly poison that arose during the churning of ocean called Sāgara Manthana (सागरमन्थन), and by this deed, Shiva became Neelkanth Mahadev.
  4. According to some other legends, Shivaratri is the day when Mahadev performed the divine dance of creation, preservation, and destruction; in our native language known as the Tandava dance or Tāṇḍava nṛtya.

These legends or Mythological Stories are often regarded as The Origin Of Shivaratri or Maha Shivaratri. But there is one more mythological story of the origin of Shivaratri and as well as the creation of Phases Of The Moon.


Why We Celebrate Maha Shivaratri - In My View

It was the time when the Adi Shakti (eternal consort of Lord Shiva) was on the earth (Bhuloka) as the Goddess Sati (long before the emergence of Goddess Parvati). Devi Sati was the daughter of the Prajapati Dakṣa (lord of all born being and son of Lord Brahma-The Creator). According to Puranas, Prajapati had so many daughters (as no of the daughters can't be a significant number as different Puranas suggest the different number of daughters).


Out of his so many daughters, Prajapati married his 27 daughters to Chandra (Moon God or we can say to the natural satellite of the planet earth). These 27 wives of Chandra are the 27 Nakshatras (the constellations) which are on the moon's orbit. Chandra was the son of Vedic sage Atri (one of the Saptarishi) and Anasuya.

Even though Chandra married 27 daughters of Prajapati Daksha, yet he overly favored only one daughter i.e Rohini. Chandra while being in love with Rohini, he neglected the needs and responsibilities of the other 26 wives over Rohini. So as a result, some of the wives of Chandra complained about the neglecting behavior of Soma to their father Daksha. As a father, Daksha became furious over Chandra dev unforgivable deeds. And for this Prajapati Daksha cursed Chandra to wither and die or he will have to suffer from "Kshay" - deterioration of body within a limited period of time. Only Mahadev could protect the Chandra from the wrath of Prajapati Daksha.

During that time, Prajapati Daksha had also abandoned the worshipping of Lord Shiva i.e Daksha had cursed Lord Shiva that no one will pray to him. Only Mahadev could free Chandrama from the curse of Prajapati Daksha. With help of Lord Vishnu (the preserver) and Lord Brahma (the creator), Devi Sati relieved Lord Shiva from the curse of Prajapati Daksha.


Later when Mahadev was relieved from the curse, that means anyone can worship Lord Shiva; then in order to get rid of the curse, Chandra worshipped and performed the hardest penance of "Mahamritunjaya Mantra" composed by Sage Markandeya to please The Supreme One. And finally, Lord himself appeared in front of Chandra. Mahadev told soma that he could not completely remove the curse given by Daksha because what Chandra had done to his wives was unforgivable.


But later for the well being of nature and planet earth, Lord Shiva agreed to relieve the Chandra from the curse of Prajapati Daksha but not completely. Mahadev explained Chandra that he had to face the curse but only half of it. So Mahadev placed him on his head ( that is why Mahadev is known as Chandrashekhara) and gave Chandra the boon that, " in a month, for 15 days he would face the curse and decrease in size and for 15 days he would grow to the larger extent" The totally diminished Chandrama is nothing but "AMAVASYA or NEW MOON DAY" and the full sized Chandrama is "POORNIMA or FULL MOON DAY.

The place where Chandra worshipped Lord Shiva is now known as Somnath temple which is in Gujrat made by Chandradev himself. this day, when Lord Shiva protected the Chandradev from the wrath of Prajapathi Daksha and also the Devi Sati relieved Lord Shiva from the curse of Prajapathi Daksha come to be known as the origin of Mahashivaratri festival. This is also the day when Mahadev accepted Devi Sati as his eternal consort.



How To Do Maha Shivaratri Fasting?

Mahashivaratri fast is considered as one of the most important fast for the devotees of Lord Shiva. As Shiv Purana goes on to say that if a devotee observes Shivaratri Vrata with sincerity, pure devotion, and love; he is blessed with the divine grace of Lord Shankara.

It is a well-known fact that, 
"Mahadev to bas ek Bel Patra (Aegle marmelos) se khiche chale aate hai" 

But for those who want to observe strict Maha Shivaratri fast should take bath with water that is being boiled with black sesame seeds. As of bathing with sesame seeds water, it washes away the bodily impurity. after bathing, a devotee should put fresh clothes, then devotee should visit the nearest Lord Mahadev temple in order to pray and perform the rituals such as ShivLingam bath with water, milk, and honey etc.
ShivLingam-Abhishekam
ShivLingam Abhishekam
Following the sacred bath, a devotee should apply Haldi-Kumkum on ShivaLingam and place white and pink colored flowers. After that, a devotee should place Bel Patra on the top of the ShivaLingam. in the praise of Lord Shankara, aarti and bhajans are sung to invoke the blessings of large-hearted Lord Bhole Nath.


Prayers To Lord Shiva

There are so many different kinds of prayers that are offered to Lord Bhole Nath during Maha Shivaratri. In my view, while ShivLingam Abhishekam a devotee should pray,
"O Lord ! I will bathe Thee with water, milk, etc. Do Thou kindly bathe me with the milk of wisdom. Do Thou kindly wash me of all my sins, so that the fire of worldliness which is scorching me may be put out once for all, so that I may be one with Thee-the One alone without a second"

Lord Shiva Boon To Whoever observe Mahashivaratri

Lord Shiva Quote

Maha Shivaratri ka Vrat Visesh Falon Ko Pradan Karne Wala Hai. Is vrat ko rakhne se Purusho (man) ki saari manokaamnaae puri hongi, Suhaagan strio (married girl) ka suhaag bana rahega, kuwari ladkio (unmarried girl) ko mann chaha var milega. 

Though my blog is related to the aspect of physics. But as a devotee of Lord Shiva, I could not stop myself from writing an article on Maha Shivaratri. 
ON that note, I can say that I have tried enough to give an overview that Why We Celebrate Maha Shivaratri - In My View within my reach. If there is any suggestion, I am all ears. Feel free to comment.

The Science Behind The Solar Eclipse

The Science Behind The Solar Eclipse

What Is Solar Eclipse?

A Solar Eclipse is a natural phenomenon that happens when the moon comes between the sun and the earth and blocks the sun for short interval of time. In simple terms, it's an eclipse during which the sun is obscured by the moon. During a solar eclipse, directly looking at the sun can cause serious eye damage or even permanent blindness; therefore, it is generally advised to view a solar eclipse wearing special eye protection.

How Often Do Solar Eclipses Occur?


A Solar Eclipse occurs only during the lunar phase called "The New Moon". Solar Eclipse generally occurs at least 2 times a year or at most 5 times a year (which is very rare). Just because the moon's orbit is tilted at approx 5 degrees to the earth's orbit around the sun, a solar eclipse occurs only 2 or maybe 5 times a year; otherwise, there would be a solar eclipse on every New Moon Day. If we go by the past 100 years data; Earth experiences an average of 2.4 solar eclipses every year.


Physics Behind The Solar Eclipse

There are several phenomena that basically govern the physics behind the solar eclipse.
  1. The first phenomena is the elliptical revolution of the moon around the earth and the elliptical revolution of the earth around the sun. As a result of the clockwise elliptical motion; the sun, the moon, and the earth come in line (align) with each other.
  2. As seen from the earth, the size of the sun and the moon appears to be same in size. Although the distance of the moon from the earth is much smaller as compared with the distance of the sun from the earth, yet the sun appears much much smaller than the much closer (smaller in size) moon.
  3. Each month, due to the alignment of sun and moon in the sky, moon's lunar phase appears to change; which is known as Phases Of The Moon. The first phase of the moon is called a new moon day. Only on new moon day, a solar eclipse can occur.

 From the above written physical phenomena, one can calculate that for the solar eclipse to occur; 1) there must be new moon day and 2) the moon must be in the ecliptic (the plane of earth's orbit around the sun).


Magnitude Of The Eclipse

Magnitude-Of-The-Solar-Eclipse
A complete description that how magnitude of the solar eclipse varies
Credit: Wikimedia Commons

The magnitude of the eclipse is defined as the ratio of the apparent size of the moon to the apparent size of the sun during the occurrence of an ellipse. This magnitude of the eclipse is applicable to both Lunar Eclipse as well as the Solar Eclipse. 

For the solar eclipse, if the magnitude is between 0.00 and 1.0 then the eclipse can be the annular or partial solar eclipse; and if the magnitude of the eclipse is 1.0 or above then the total solar eclipse occurs.


Types Of Solar Eclipse

There are generally four different types of a solar eclipse that are determined by how much of the sun is obscured by the Moon.
let's talk about each one of them, one by one!!

1. The Total Solar Eclipse

The Total Solar Eclipse occurs when the sun is completely obscured by the moon for a shorter period of time. In simple terms, when the sun and the moon are completely in line with the earth. During the total solar eclipse, the sunlight is totally replaced by the dark silhouette of the moon; leaving the much fainter solar corona to be visible from the earth. 

Total Solar Eclipse can only occur when the moon is at closest distance from the earth ( i.e near its perigee) because at that time the moon appears to be much large enough to completely cover the sun's bright disk (which in scientific term is known as Photosphere). When the magnitude of the solar eclipse is equal to or greater than 1; a total solar eclipse occurs.

2. The Annular Solar Eclipse

The-Annular-Solar-Eclipse

The Annular Solar Eclipse can only occur when the sun and the moon are completely in line with the earth but the moon is at the farthest distance from the earth (i.e near its apogee) because at that time the moon appears to be slightly smaller than the sun and as a result; not able to completely cover the sun's bright disk. When the magnitude of the solar eclipse is less than 1; the annular solar eclipse occurs.

Basically, on an average; The Annular Solar Eclipse occurs more than the total solar eclipse because most of the time, the moon is at the farthest distance from the earth that is at apogee.

3. The Partial Solar Eclipse

The Partial Solar Eclipse is the most commonly seen type of solar eclipse. The Partial Solar Eclipse occurs when the sun and the moon are not completely in line (aligned) with the earth and as a result, the sun is partially obscured by the moon. Partial solar eclipse is virtually unnoticeable in terms of sun's brightness.

During the partial solar eclipse, the magnitude of the eclipse varies as seen from one location to the other location. Such that the magnitude of the solar eclipse is 0.0 at the start of an ellipse, then rising to the maximum value attainable, and finally comes back at 0.0 at the end of the ellipse. These eclipses are visible over the larger portions of the earth due to Moon's Penumbral Shadow.

4. The Hybrid Solar Eclipse

Hybrid Solar Eclipse occurs between Annular and Partial Solar Eclipse

The last type of the solar eclipse is The Hybrid Solar Eclipse. It is generally a combination of the total solar eclipse and the annular solar eclipse because, at a certain location on the earth, it (hybrid) appears as a total solar eclipse; whereas at other location it appears as the annular solar eclipse. a hybrid solar eclipse is rarest among all the solar eclipse.


    When Is The Next Solar Eclipse?

    As far as the year 2018 is concerned, astronomers have calculated that there will be three solar eclipse occurrence this year. And all of the three solar eclipses occurring in 2018 will be the partial solar eclipse. The dates of the eclipse are as follow:

    1. 15 February 2018 (partial solar eclipse); also the day of Maha Shivaratri
    2. 13 July 2018 (partial solar eclipse)
    3. 11 August 2018 (partial solar eclipse)

    ON that note, I can say that I have tried to give an overview of The Science Behind The Solar Eclipse within my reach. If there is any suggestion, I am all ears. Feel free to comment.

    Earth's Tilt - The Reason For Change In The Seasons

    Earth's Tilt - The Reason For Change In The Seasons

    Summer-Fall(Autumn)-Winter-Spring-all-seasons
    Summer, Fall (Autumn), Winter, Spring

    Nearly every living being (whether human or lion or bacteria or ant) is aware of the fact that What Season Is? In fact, even if we just talk about humans only, a human being can divide one year up to four seasons such that: Summer, Fall (Autumn), Winter, Spring. Well, we can divide years in so many different ways. Like in my country ( I AM FROM INDIA ); according to Hindu Calender, a year is divided into six seasons or (Ritu) such that each season has a fixed 2-month time span of the 12-Month Hindu Calendar.

    According to the Hindu Calendar, the six seasons or Ritu are Vasanta (spring), Greeshma (summer), Varsha (monsoon), Sharad (spring), Hemanta (early winter), and Shishira (prevernal or late winter).


    What Is The Reason For Change In the Seasons?

    In a modern world, everyone is quite aware of the scientific fact that earth revolves around the sun in an elliptical model or Heliocentric Model according to the Kepler's Laws Of Planetary Motion. So as a result, one might logically assume that our planet's changing distance from the sun (when the earth is close to the sun its summer, or when the earth is far away from the sun its winter) is the reason for change in the seasons; but sadly it is not correct explanation for the reason for the change in the seasons. Though it has some effects on different seasons on earth but not the effective or sole reason for the justification for the reason for the seasons.

    Earth's Tilt Is The Reason For Change In The Season !!

    Earth's-Obliquity
    Earth's axial tilt (obliquity) is currently about 23.4°

    The reason for the season is Earth's Tilt (Earth's axis of rotation) relative to its orbital plane while traveling in a loop (elliptical) around the sun every year. The angle of Earth's Tilt is approximately 23.4 degrees. In astronomical world, Earth's Tilt is also known as "Obliquity". The hemisphere (northern or southern) which is tilted toward the sun experiences summer and the hemisphere which is tilted away from the sun experiences winter; ( which we will talk in the later section). 


    What Is The Reason For Earth's Axial Tilt?

    The correct reason behind the Earth's Tilt is still a puzzle to solve. There are so many controversial or hypothetical theories related to the Earth's Axial Tilt, but none of them is satisfactory. One theory suggests that; during the early age of our solar system when our planet earth (during its young age) collided with some early heavenly body which later became the moon of our planet Earth. And as a result of that collision, there is an axial tilt on earth of 23.4 degrees.

    On the other hand, some scientists suggest that planet earth may have tilted itself to gain its ecological balance. One mindful person can regard that both of the above theories are just theoretical and even may be hypothetical because when that happened we were not there. All we can do is argue!!


    Who Discovered the Earth's Tilt?

    The Earth's Axial Tilt or Obliquity is surprisingly known for a very long time. According to the historical scientific writings; if we go back to the scientific timeline, the earth's tilt had been logically calculated in Ancient India and China around 1100 BC. Later in 1437, Ulugh Beg of Samarkand, Uzbekistan who was Astronomer, a mathematician as well as the Sultan confirmed the earth's Obliquity as 23°30′17″ (23.5047°).

    Later in the modern world or western world, the first accurate calculation of earth's tilt was calculated by a Danish Astronomer and a nobleman Tycho Brahe in the late 1500s. And by using his calculations, observations and written works; Johannes Kepler developed his set of planetary law which in today's world is known as Kepler's Laws Of Planetary Motion.


    How Season Changes Due To Earth's Tilt To Different Hemisphere

    Earth's-Tilt -The-Reason-For-Change-In-The-Seasons
    Illumination of Earth at each change of astronomical season

    It is a world-recognized fact that is if divide our sphere (planet earth) what we get is two hemispheres that are commonly known as The Northern Hemisphere and The Southern Hemisphere. As we discussed in the earlier section that, the hemisphere which is tilted toward the sun during a specific period of time experiences summer and longer days; and the hemisphere which is tilted away from the sun experiences winter and shorter days. Due to the cyclic rotation of the earth around the sun, the hemisphere tilted toward or away from the changes simultaneously.


    Likewise, when the northern hemisphere is tilted toward the sun, it experiences the warm weather, summer as well as the longer day (daylight); while on the other hand at the same time southern hemisphere is experiencing the cold weather, winter as well as the shorter day and vice versa. During may, June and July, Northern Hemisphere experience summer; and during November, December and January,  Southern Hemisphere experience summer.

    So from above observation, we can conclude that due to the Earth's Tilt, "northern hemisphere's summer solstice = southern hemisphere's winter solstice". In simple words, when there is summer in the northern hemisphere, at the same time there is winter in the southern hemisphere or vice-versa.

    As far as equator is concerned; there is no change in the season because each day sunlight strikes the equator at the same angle. In simple words; every day of the year, equator receives 12 hours of sunlight. 

    ON that note, I can say that I have tried to give an overview of Earth's Tilt - The Reason For Change In The Seasons within my reach. If there is any suggestion, I am all ears. Feel free to comment.

    8 Lunar Phases Of Moon - From New Moon To Full Moon To New Moon

    8 Lunar Phases Of Moon - From New Moon To Full Moon To New Moon

    8 Lunar Phases Of Moon--From New Moon To Full Moon To New Moon
    8 Lunar Phases Of Moon - From New Moon To Full Moon To New Moon
    Credit: wikiHow
    In today's world, each and everyone is quite aware of the fact that Moon Is The Natural Satellite Of The Earth which revolves around the Earth in approx 27.32 days which is also known as the Lunar Month. While revolving around the Earth, only half of the Moon's surface gets illuminated by the Sunlight because of the Astronomical Phenomena known as the Synchronous Rotation or Tidal Clocking making day and night on the Moon.

    The Sun lits the Moon as well as the Earth. As the Moon orbits around the Earth, how much light we can see from our earthly point of view are known as the Phases Of The Moon or Lunar Phases Of The Moon. In simple terms, every day we observe the changing size of the moon; is scientifically known as the Phases Of The Moon or Lunar Phases Of The Moon


    Why Does The Moon Changes Its Shape?

    The Moon's shape changes mainly due to the following reasons:


    1. The Moon orbits around the Earth.
    2. The Moon and the Earth orbits around the Sun.
    3. The Sun lits or illuminates both Earth and the Moon because both Moon and the Earth reflect light from the Sun. 
    4. The Moon's Lunar Phases or Phases Of The Moon are produced due to the alignment of the Moon and the Sun in the sky.
    5. The half part of the Moon facing the Sun is illuminated and on the other hand, the half part facing away the Sun is always in the darkness (The Dark Side Of The Moon) due to the astronomical phenomena known as Synchronous Rotation or Tidal Clocking; that's why we only get to see one side of the Moon ever. 


    8 Lunar Phases Of Moon

    The Lunar Phases Of The Moon are cyclic in nature starting from the new moon to full moon in approx 27.32 days. There are 8 Lunar Phases Of The Moon that occurs at a specific location on the Moon's Orbit. Technically, The Lunar Month can be divided into 4 Primary Phases that are:- New Moon, First Quarter Moon, Full Moon, Last Quarter Moon; and 4 Secondary Phases that are:- Waxing Crescent Moon, Waxing Gibbous Moon, Waning Gibbous Moon and Waning Crescent Moon.

    Now, Let's Get To Know Each Lunar Phases One By One

    1. New Moon

    New-Moon
    credit:earthsky.org
    A New Moon is the first phase of the Lunar Month Cycle which occur when the moon comes between the Earth and the Sun. During a new moon day, the side of the moon facing earth is not illuminated by the sunlight due to the alignment between the sun and the moon. Only on a new moon day, a Solar Eclipse can occur.


    2. Waxing Crescent Moon

    When the bright part of the moon is getting bigger, the lunar shape of the moon is waxing or growing into its crescent phase; what we call is A Waxing Crescent Moon. It is also known as a Young Moon.

    Sometimes during the waxing crescent phase of the moon; rest of the moon is also faintly visible because of the reflection of sunlight from earth to the moon. This astronomical phenomenon is known as Earthshine.




    3. First Quarter Moon

    First quarter means the moon is one-fourth of the way around the earth; hence the name "First Quarter Moon". It generally occurs one week after the new moon. Sometimes, it is also called as Half Moon; as we see exactly half (right side) of the illuminated portion of the Moon's Lunar Surface.


    4. Waxing Gibbous Moon

    When the moon's lunar surface is more than half-lit or illuminated, A Waxing Gibbous Moon occurs. A lunar shape is getting bigger (waxes). It occurs between the first quarter moon phase and the full moon phase. A waxing gibbous moon's phase is larger than the semi-circle but quite smaller than the full circle.


    5. Full Moon

    A full moon day is observed when the entire moon's surface is lit or illuminated by the sunlight. It occurs when the moon is totally on the opposite side of the earth. On full moon day, the moon looks like a complete circle. Only on a full moon, a lunar eclipse can occur.

    After the full moon day is observed, the lunar shape of the moon starts to get smaller (decrease) that means the moon is waning; A Waning Gibbous Moon Occur. A waning gibbous moon is also regarded as the reverse of the waxing gibbous moon. It occurs between the full moon phase and third quarter phase.




    7. Third Quarter Moon

    After the appearance of the glorious full moon, the moon starts to wane (decrease or getting smaller); the third quarter moon occurs. Third quarter means the moon is three-fourths of the way around the earth; hence the name "Third Quarter Moon"

    The third quarter moon is also regarded as the reverse of the first quarter moon. Sometimes, it is also called as half moon; as we see exactly half (left side) of the illuminated portion of the moon's lunar surface.

    The last lunar phase of the moon before returning to the new moon phase is known as the waning crescent moon. When the bright part of the moon is getting smaller, the lunar shape of the moon is waning or decreasing into its crescent phase; what we call A Waning Crescent Moon.

    By the end of the 27.32 days Lunar Month Cycle, the moon has vanished almost entirely. And we are again back to the new moon to start again the ever repeating cycle.
