Three ultra-massive galaxies from the early universe, named "red monsters" show star formation happened faster than believed.

These wavelengths—a portion of which we experience as color—have long warned us of danger and enticed us to closely inspect the objects we encounter. In a new photo book, The Universe in 100 ...

Inflation is also popular because it potentially explains why the energy density in the early universe varied slightly from place to place. This is important because the denser regions would have ...

They get their striking color from their extreme amount of dust ... to researchers that the formation of stars in the early universe was far more efficient than they had previously thought ...

Today, the dominant theoretical approach combines string theory, a powerful mathematical framework with no successful physical predictions as yet, and “cosmic inflation”—the idea that, at a very early ...
