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

Jets blasting from supermassive black holes cause gas to cool and fall toward that cosmic titan in a cosmic feeding process.

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

Galaxies like the Milky Way grow by merging with smaller galaxies over billions of years, unlike dwarf galaxies, which have long been thought to lack the heft to attract mass and grow in the same way.
