When ever the moon passes throw a portion of the earths shadow it formes a lunar eclipse.The way it can occur is when the [|Sun], [|Earth], and [|Moon] are aligned exactly, or very closely so, with the Earth in the middle. There is always a [|full moon] the night of a lunar eclipse. The type and length of an eclipse is depended on the Moon's location relative to its [|orbital nodes]. The [|next total lunar eclipse] occurs on December 21, 2010. The next eclipse of the Moon is a penumbral eclipse on [|July 7, 2009].

2.What is a [|black hole]? A black hole is a hole in space that has such a big gravintatinel pull that nothing can escape not even a light cant escape. A black hole is a hole in space that does not have any light. A [|black hole was created]by a gravitational collapse of a massiv star. If a black hole were to suck you up it would rip you to pieces. The reason it would rip you to pieces is because of how strong the gravitationly pull is. [|gravitaional field]

3.What are stars? Stars are massive balls of plasma that is held together by its own gravity.(http://en.wikipedia.org/wiki/Stars)
 * 4.How many galaixes are there?

The Hubble Space Telescope (**[|**HST**]**) site estimates there are hundreds of billions of** [|**galaxies**] **in the** [|**universe**]**. A recent German super-computer simulation estimates that the number may be as high as 500 billion! Can someone please clarify the accepted educated ballpark figure?

5.why isn't pluto a planet anymore? Nearly every schoolchild who has grown up in the latter part of the 20th century has been taught that Pluto  was not only the furthest  planet  from the Sun, but also the smallest in our solar system. For now, science books and astronomical charts will have to be revised due to a  decision made by the International Astronomical Union (IAU) during  a  meeting in 2006. The decision, which included eight days of zealous [|debate] and a  nearly split vote, resulted in  Pluto  being unceremoniously downgraded to  a  dwarf or minor  planet  status. Stripped of its “classic” planet  status,  Pluto  is now what amounts to  a  third class citizen in our solar system. It’s not so much that Pluto  was intentionally removed from the classification, but rather that the IAU outlined  a  new definition of what constitutes  a  classic  planet. Pluto no longer meets the standards. Now, the list of classic planets in our solar system includes Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.

6.How much does the sun way? It weighs 2,000,000,000,000,000,000,000,000,000,000 kg (a 2 with 30 zeros kg, or about 4.4 with 30 zeros lbs). That weighs a lot! Here is the website I found this at, http://ds9.ssl.berkeley.edu/solarweek/DISCUSSION/howbig.htlm.

7.Will the sun explode? No the sun will not explode .But the sun will keep on growing and eventually get so big and destroy earth.The sun will get so big because it is burning hydrogen.And the hydrogen is adding extra layers to the sun.
