The new composite image, which combines hundreds of photos from the Hubble Space Telescope, shows the Andromeda Galaxy with more than 200 million individually resolved stars.

“It is necessary to understand which GCs belonged to satellite galaxies like Sgr dSph to understand how the Milky Way formed and evolved. Furthermore, since some of these GCs are comparable in ...

Also in the Local Group are a couple dozen dwarf galaxies. Several of these dwarf galaxies are satellite galaxies, orbiting around the large galaxies. The Milky Way has two prominent satellite ...

ABSTRACT We examine a possible connection between the anisotropic distribution of satellite galaxies around giant spiral galaxies and the evolution of satellite systems. The observed polar anisotropy ...

After hundreds of hours of observations, researchers captured a highly detailed image of a long filament of the "cosmic web" ...

The haloes of galaxies show clear evidence for this, says the paper; faint streams and shells of stars, left by merging satellite galaxies, and star clusters scattered in their outskirts.

By studying galaxies early in their formation and in ... Its environment -- meaning whether it is isolated or functioning as a satellite of a larger system -- is an important factor.

This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way's satellite galaxies, the Large Magellanic Cloud. The Large Magellanic Cloud is a dwarf ...
