the Milky Way, consists of more than a hundred billion stars strung across tens of thousands of light years. Galaxies are broken down into three basic shapes, with many different subtypes.

What are some of the different types of galaxies? The Milky Way is a spiral galaxy, which means it's flat, large and has several arms that spiral around a central bulge, Samuel said. Spiral galaxies form stars at a moderate rate and typically have a mass similar to the Milky Way. When...

There are low excitation radio galaxies too, which, on the other hand, are likely very old galaxies where relatively little material is falling into the black hole and no merger signatures are visible. These objects were likely triggered by mergers but looked very different at that time and ...
The birth of the first stars represents the beginning of a sequence that produced all the worlds and living beings of the universe. Simulations can be used to study the critical first steps that telescopes cannot yet see.

The majority of bright early-type galaxies in this field are found at redshifts $z \\leq 1.3$ to share common properties with those of high-z cluster samples, as for the age and mass of the dominant stellar population -- which are found to be as old as 3-5 Gyr and as massive as...
