The Launch Pad Monday, 9/19/11 What is a “star?” A star is a large, dense sphere of incandescent gas (Incandescent means emitting light as a result of being heated.) How are stars powered? Stars are powered by thermonuclear fusion reactions exerting outward pressure that opposes the force of gravity. Where does thermonuclear fusion take place in a star? Thermonuclear fusion takes place in the core of the star.

Recent Events in Science Hubble telescope reveals farthest view into universe ever http://www.foxnews.com/science/2012/09/25/hubble-telescope-reveals-farthest-view-into-universe-ever/ Read All About It! ?? The Hubble Space Telescope has captured the farthest-ever view into the universe, a photo that reveals thousands of galaxies billions of light-years away. The picture, called eXtreme Deep Field, or XDF, combines 10 years of Hubble telescope views of one patch of sky. Only the accumulated light gathered over so many observation sessions can reveal such distant objects, some of which are one ten-billionth the brightness that the human eye can see.
