New images released by NASA's Hubble Space Telescope are of the Pegasus Dwarf spheroidal galaxy, also known as Andromeda VI. Pegasus is located in the Andromeda Galaxy, also called Messier 31 ...

While the object has been detected in previous sky surveys, it has now been conclusively identified as a spheroidal dwarf galaxy. The discovery is important for cosmological models involving dwarfs.

As a dwarf spheroidal galaxy, it lacks any distinctive spiral arms. The dwarf spheroidal galaxies that are found near massive galaxies are typically poor in gas and dust, because they’ve been ...

These are the first detections of this type of rotation in dwarf spheroidal galaxies ... the data from Gaia are used mainly to study our Galaxy, this ESA mission has also opened a new window ...

About 2/3rds of the "dwarf spheroidal galaxy" is made up of star material formed 12 billion years ago, just a billion years and some change after the Big Bang. The find was published in the latest ...

The researchers determined that this galaxy — nicknamed Bedin 1, after discovery team leader L. R. Bedin of the INAF-Osservatorio Astronomico di Padova in Italy — is a "spheroidal dwarf" just ...

Dwarf spheroidal galaxies are much bigger than globular clusters. The Pegasus dwarf spheroidal galaxy, which orbits the famous spiral galaxy M31 in Andromeda, spans 2,000 light-years. A newly ...
