Question

and lunar eclipse, full moon, new moon...
plz explain in detail...

Answer 1

• A blood moon is a term used to describe a total lunar eclipse, which is when the moon appears darkened as it passes through the Earth's shadow. ... The next lunar eclipse visible in the U.S. will be on Jan. 21, 2019, according to NASA. It won't be a blue moon, but it will be a super moon.
• A "blood moon" happens when Earth's moon is in a total lunar eclipse. While it has no special astronomical significance, the view in the sky is striking as the usually whiteish moon becomes red or ruddy-brown. The last blood moon on Jan. 20-21, 2019 coincided with a supermoon and the Full Wolf Moon, earning it the title "Super Blood Wolf Moon."
• The next blood moon will happen during the total lunar eclipse of May 26, 2021, which will be visible from parts of North America, Australia, the Pacific and Asia.
• A blue moon is an additional full moon that appears in a subdivision of a year: either the third of four full moons in a season, or a second full moon in a month of the common calendar.
• A supermoon is a full moon or a new moon that nearly coincides with perigee—the closest that the Moon comes to the Earth in its elliptic orbit—resulting in a slightly larger-than-usual apparent size of the lunar disk as viewed from Earth. The technical name is a perigee syzygy or a full Moon around perigee.
• A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned, with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.
• The full moon is the lunar phase when the Moon appears fully illuminated from Earth's perspective. This occurs when Earth is located between the Sun and the Moon (more exactly, when the ecliptic longitudes of the Sun and Moon differ by 180°). This means that the lunar hemisphere facing Earth – the near side – is completely sunlit and appears as a circular disk, while the far side is dark. The full moon occurs once roughly every month.
• In astronomy, the new moon is the first lunar phase, when the Moon and Sun have the same ecliptic longitude. At this phase, the lunar disk is not visible to the unaided eye, except when silhouetted during a solar eclipse. Daylight outshines the earthlight that dimly illuminates the new moon.

$\large{\boxed{\red{\textbf{ Thanks\:For\:Ansking}}}}$

A supermoon is a moon that is full when it is at its closest point in an elliptical orbit around the Earth and a total lunar eclipse or blood moon in which Earth's shadow upon the lunar eclipse gives it a reddish colour.

When Earth's moon is in full eclipse then a "Blood Moon" occurs. Actually the super blue moon is the combination of blue moon, super moon and total eclipse, all the three are rare events. The striking feature of this Moon is that instead of white colour it becomes red or ruddy-brown. When the moon crosses into the shadow of the Earth it becomes blood red in colour.

Do you know that the term "blue moon" is used when the full moon appears twice in less than 28 days because moon takes approximately 27 days to orbit the earth. Therefore, we can say that blue moon happens on an average every three years.
