Astronomers recently placed the Milky Way on the fringe of a huge supercluster.
For example, based on the ages of stars, we know the Milky Way is about 13.2 billion years old.
Even worse: "Eight in ten kids born in the US today will never see the Milky Way."
One magnetar is only about a light-year from the black hole at the center of the Milky Way.
New research shows early galaxies were much bigger—some 10 times the mass of the Milky Way—than astronomers expected.
New stars swam into their autumnal places, and the Milky Way came majestically to its own.
Then he reached the Milky Way and there was plenty of light.
It is just at the edge of the Milky Way, and you are to look for three stars in a straight line, with the middle one brightest.
Had she discovered the trail which, like the Milky Way, led to them?
It suggests a nebulous dim puff of star-dust lost in the blaze of the Milky Way.
|Milky Way |
The spiral galaxy that contains our solar system. Made up of an estimated two hundred billion stars or more, it is seen from Earth as an irregular band of hazy light across the night sky. The solar system is located in one of the revolving spiral arms, about 50 light-years north of the galactic plane and some 27,700 light-years from the galaxy's center, which lies in the direction of the constellation Sagittarius. It takes approximately 250 million years for the solar system to orbit the galactic center, which is believed to contain a massive black hole. The Milky Way measures about 100,000 light-years in diameter and is the second largest galaxy, after the Andromeda Galaxy, in the cluster known as the Local Group. See also spiral galaxy.
