英语太空手抄报内容50字英文
The astronomers said the stellar black hole may have been created by an exploding star in the inner disk of the Milky Way.The black hole is 6,000 to 9,000 light years away,the researchers said.A report on the observations appears Tuesday in the journal Astronomy and Astrophysics.A black hole is a point in space that is so dense with matter that its gravitational field will not let anything-not even
light-escape.Stellar black holes,equal to 3.5 to about 15 solar masses,can be formed by the collapse of a single massive star.But galactic black holes,such as those in NGC6240,are much larger,equal perhaps to millions of solar masses,and are usually at the center of galaxies.The Milky Way,home galaxy of the sun and its planets,is thought to have a black hole at its center.With its immense gravitational pull,a black hole can suck in gas,dust and other matter from the surrounding space.Entire stars can be stripped and pulled into the bottomless maw.As it spirals in at near light speeds,matter captured by a black hole heats by millions of degrees and gives out intense radiation in several parts of the
spectrum,including X-rays.The orbiting Chandra observatory is able to detect these X-rays and relay the data to Earth for study
by astronomers.
