Lunar Eclipses

There is the total Eclipse, where the moon totally covers the sun. Then there is a partial eclipse, where the moon passes across the sun, but not right through the middle - so we just see a 'bite' out of the sun at most. Then there is an annular eclipse, where the moon goes directly in front of the sun, but the distance is such that it is not able to cover the sun completely - the moon appears too small and the sun shines around it to make a ring. There is also a hybrid, which is where at some points on earth a total eclipse may be seen, but in other locations an annular eclipse may be seen. These are all four types of solar eclipse, there is also the lunar eclipse where the earth obscures light to the moon.

The last good total lunar eclipse completely visible in India was on September 7, 2006. On March 3, 2007, the Moon set over India while an eclipse was in progress.

They have existed as long as the Earth and Moon have been in existence. It would be difficult to put a date on it, but mankind has been aware of them for thousands of years. The earliest record is from 2800BC.

A lunar eclipse can only happen during a full moon when the Earth is positioned between the sun and the moon, casting its shadow on the moon.

A total lunar eclipse happens when the Earth blocks out the moon entirely from the sun.

One may occur when the moon is full.

A Lunar eclipse happens when the sun moon and earth are all lined up, with earth in between the sun and the moon. At this position, with the sun behind us and the moon in front of us, we see a full moon, as the light is reflected back of the surface. The lunar eclipse happens when the earths shadow can be seen on the moon.

We don't always get a Lunar eclipse when there is a full moon though, as we don't often get a perfect enough line up. This is due to the orbits of the Earth and moon not being perfectly flat.

Red light has the least energy of all the visible spectrum.

When the moon passes the oppersite side of earth to the sun (lunar eclipse) the earths atmosphere acts like a huge prism.

As we all remember from science at school when light enters a prism the red light bends more than the blue light. The red light is bent around the earth and goes on to light the moon. The blue light is bent a little but not enough to hit the moon.

The Moon has been ducking into Earth's shadow about twice a year since the Moon was formed, probably about 4 billion years ago.

The main parts of a lunar eclipse are the penumbral phase, when the moon enters Earth's faint outer shadow; the partial phase, when part of the moon is in Earth's dark inner shadow called the umbra; and the total phase, when the entire moon is within the umbra, giving it a reddish hue known as a "blood moon."

First of all, a lunar eclispe starts when a full moon moves into the shadow of a earth.

The sky is very dark, but you can still see the moon. The moon holds an orange or pinkish hue. Its hard to tell.

The next eclipse will be a solar eclipse on July 11, 2010; if you live on Easter Island, it should be spectacular. The path of totality includes a few islands in French Polynesia, a LONG swath of the South Pacific, Easter Island and tiny slices of Argentina and Chile.

After that, all of North America will experience a total lunar eclipse on December 21, 2010.

And you can check out the NASA Eclipse web page for a list of all eclipses from 2000 BC to 3000 AD at the link below.

A total lunar eclipse can last up to a few hours, typically around 3-4 hours from start to finish. This includes the partial phases before and after the total phase when Earth's shadow partially covers the moon.

The Sun, Moon, and Earth are all aligned in both.

Lunar breccias are thought to be the result of impact events on the Moon's surface, where rocks and debris are shattered and then fused together. This process creates a heterogeneous mixture of rock fragments with varying sizes and compositions.

Since solar eclipses go by quickly, people stare too long and because their pupils are large too let in more light because of the darkness, the sun comes back quickly and all that light goes into your big pupil before it has the chance to get smaller, therefore your retina pretty much gets burned out.

Lunar eclipses can be observed only during the night and only when the moon is far from the sun. Solar eclipses can be observed only during the day and only when the moon is near the sun.

At the time of the new moon - that's about the only generality that would be accurate. You can see the catalog of all eclipses from 2000 BCE to 3000 AD at the NASA Eclipse Web Page at the link below.

The new moon is the monthly phase of the moon where it is completely unlit (or as near to being completely unlit as possible that month). If you think about it, this is going to happen when the moon is between the earth and the sun. New moon happens when it is as close as it can be to casting a shadow on the earth. The moon doesn't cast a shadow on the earth every month, because of the relationship of the orbits of earth and moon. Every now and then, the moon does cast a shadow on the earth at the time of new moon. When this happens, the moon is eclipsing the sun. There are several kinds of solar eclipse, and few things are as beautiful or as awesome as a total solar eclipse.

Generally, yes; there are normally two lunar eclipses and two solar eclipses each year.

Bot not always. Here in 2009, because the Moon, Earth and Sun aren't lining up quite as precisely as they usually do, we have four partial or "penumbral" lunar eclipses this year, and two partial or annular solar eclipses.

In a "penumbral" eclipse, the Moon only gets partly into the Earth's "penumbra" or outer shadow, and in many cases you can hardly see any darkening of the Moon. In a partial eclipse, the Moon gets completely into the outer shadow but only partly into the inner "umbra", the total shadow of Earth.

Here's what's going on. The Sun is enormous, WAY bigger than the Earth. The Earth's shadow is a cone-shaped region that narrows down to a point. The inner cone or "umbra" is when the entire Sun is hidden behind the Earth, and the outer cone or "penumbra" is when part of the Sun is behind the Earth, and part of it is exposed.

In a partial solar eclipse, Sun is being blocked by the Moon. It doesn't get dark, until about 75% of the sun is hidden, because the part of the Sun that isn't hidden is still very bright. A penumbral lunar eclipse is like a partial solar eclipse as seen from the Moon.

In a penumbral lunar eclipse the entire Moon is is PART of the sunshine, but some fragment of the Sun is behind the Earth.

because it takes a while for the moon to come right im between the sun and earth in the solar eclipse.

The next lunar eclipse will occur on May 26, 2021. It will be a total lunar eclipse visible from various parts of the world.

As of 2011, Uranus has 27 known moons.

Before the Voyager 2 encounter, only five satellites of Uranus had been discovered. They form a remarkably regular system with low orbital eccentricities and inclinations close to the plane of the planet's equator. The Voyager cameras found 10 (actually 11) additional small satellites, including two that may serve as gravitational "shepherds" for the outermost ring. Like Jupiter, Saturn, and Neptune, Uranus also has more distant, irregular satellites (moons that move in orbits with high inclinations or eccentricities). These are likely captured asteroids, and all but one orbit in the opposite direction from the larger moons.

The 27 moons are :

1. Cordelia

2. Ophelia

3. Bianca

4. Cressida

5. Desdemona

6. Juliet

7. Portia

8. Rosalind

9. Mab

10. Belinda

11. Perdita

12. Puck

13. Cupid

14. Miranda

15. Francisco

16. Ariel

17. Umbriel

18. Titania

19. Oberon

20. Caliban

21. Stephano

22. Trinculo

23. Sycorax

24. Margaret

25. Prospero

26. Setebos

27. Ferdinand

The three bodies are arranged in a straight line and in the same plane,

with the earth in the middle.
