The Andromeda Galaxy, located 2.5 million light years away, has fascinated observers for centuries. Once believed to be part of the Milky Way, everything changed in 1923 when Edwin Hubble identified ...

The universe is undergoing an accelerated expansion, but the rate of that expansion has been a very controversial topic over ...

Our little Local Group, by contrast, contains roughly 50 confirmed and possibly 30 unconfirmed galaxies, most of them unimpressive dwarfs. Many, perhaps most, galaxies exist in such small groups ...

In the local group of galaxies that also includes the Andromeda Nebula and our Milky Way, there are about 100 billion stars. According to astronomers' calculations, there should be many more.

A newly discovered dwarf galaxy in the Local Group has been found to have formed in a region of space far from our own and is falling into our system for the first time in its history, according ...

A recent sky survey has turned up eight new members of our Local Group of galaxies, including a new class of ultra-faint "hobbit" galaxies and what might be the smallest galaxy ever discovered.

Our local supercluster spans 10 times the diameter of the Local Group, gathering smaller groups and clusters of galaxies together into a galactic megacity. Skip to content Introducing the all-new ...

For galaxies like our own, we'll remain bound to our local group, including Andromeda, Triangulum, and about 60 additional galaxies, until they all merge together many billions of years in the future.

A recent sky survey has turned up eight new members in our Local Group of galaxies, including a new class of ultra-faint "hobbit" galaxies and what might be the smallest galaxy ever discovered.

The gravitational attraction from this large mass concentration in our cosmic neighbourhood may have an important effect on the motion of our Local Group of galaxies including the Milky Way.
