A global team led by UMass Amherst identified dusty, star-forming galaxies nearly 13 billion years old, bridging gaps between early ultrabright and quiescent galaxies in the universe.

The three ultra-faint dwarf galaxies reside in a region of space isolated from the environmental influence of larger objects. Containing only very old stars, they support the theory that star ...

Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests. The insights upend theories of ...

Researchers have now seen the formation of three of the earliest galaxies in the universe, more than 13 billion years ago. The sensational discovery contributes important knowledge about the universe.

The existence of massive, elliptical galaxies in the early universe has puzzled astronomers for two decades. An international ...

Metallicity distribution of the first supernovae at 10 million years after the explosion. The supernova ejecta (orange region) has expanded to a radius of 1 kpc and enriched the surrounding gas to ...

In the vast darkness of the early universe, a spiral of light named Zhúlóng offers a new glimpse into cosmic history. This galaxy, shaped like our Milky Way, formed just a billion years after the Big ...

Researchers led by a Rutgers University-New Brunswick astrophysicist, who looked deeply into space at a period known as "Cosmic Noon," about 2 billion to 3 billion years after the Big Bang, have found ...

Black holes not only existed at the dawn of time, they birthed new stars and supercharged galaxy formation, a new analysis of James Webb Space Telescope data suggests. Black holes not only existed at ...
