This is called the “heat death” of the Universe, but you can think of it instead as the death of heat. There will be no more differences in temperature anywhere, which means thermodynamics shuts down, ...

It's all thanks to multi-object spectroscopy, which measures the redshift of these galaxies, and hence the distance to them in an expanding universe, in an observed volume of space. With such ...

Ultra-faint dwarf galaxies, cosmic 'ghost towns,' offer new insights into the early universe and star formation.

Astronomers used NASA's James Webb Space Telescope to reveal 44 stars in a galaxy so far away, its light dates to when the universe was half its age.

A new computational method gleans more information than its predecessors from maps showing how galaxies are clustered and threaded throughout the universe.
