The Milky Way and Andromeda are part of a cluster of about 100 galaxies, held together by gravity, known as the "local group." For more than a century, scientists have known Andromeda is creeping ...

The Andromeda Galaxy, our Milky Way’s colossal neighbor, lies 2.5 million light-years away yet shines visibly in dark skies.

A decade of observations by NASA’s Hubble Space Telescope has produced the sharpest and most detailed images of the Andromeda ...

Though astronomers have known that Andromeda is careening toward the Milky Way since the turn of the 20 th Century, they weren’t sure how direct, or glancing, the clash would be. But in 2012, a ...

The Andromeda galaxy lies just beyond (...OK, about 2.5 million light-years beyond) our galaxy, the Milky Way. For the past hundred years or so, scientists thought these galaxies existed in a ...

The Milky Way and Andromeda are not, however, alone in this little corner of the cosmos. They belong to a small group of galaxies within a radius of about 5 million light-years from the Milky Way ...
