Our sun is in the MILKY WAY galaxy, which measures about 100, 000 light-years across. That long thin milky bright shape across the middle of the night sky is made up of about several billion stars in our galaxy. Our galaxy is a spiral(旋转的) galaxy. but there are other types.The...
The theoretical abundance of habitable worlds among the estimated 200 billion stars of our home galaxy suggests that more powerful telescopes might glimpse the faint signature of far-off planet, proving that, in size and temperature at least, we are not alone in the universe....
The Milky Way galaxy is home to 400 billion stars and our own sun and solar system. It is nearly 120,000 light-years across and a shining example of a spiral galaxy. See some of the most amazing views of our Milky Way galaxy ever captured by amateur and professional astronomers in this...

In one of the most comprehensive multi-observatory galaxy surveys yet, astronomers find that galaxies like our Milky Way underwent a stellar "baby boom," churning out stars at a prodigious rate, about 30 times faster than today. Our Sun, however, is a late "boomer." The Milky Way's star...
