Star formation across the universe has fallen dramatically over the past 4.5 billion years, but astronomers have uncovered a ...

Star formation in galaxies is closely linked to molecular gas. In the distant past, when galaxy interactions were more common ...

A new study finds that two early-universe objects thought to be faint quasars are actually extraordinarily luminous galaxies ...

The process of galaxy merging reshapes cosmic structure by driving dramatic changes in the distribution and state of interstellar gas, thereby governing the rates and locations of star formation.

Galaxies are making far fewer stars even though much of their atomic hydrogen reservoir remains surprisingly intact.

The universe has been having fewer and fewer stellar "babies." Over the past 4.5 billion years, the rate of star birth has ...

Inside-out growth and stellar migration in the Milky Way: Inside the star-forming disc (within ~12 kpc), abundant cold gas fuels continuous star formation, producing young stars. Beyond this break ...

At the heart of most galaxies lies a supermassive black hole — a ginormous entity with a mass so large, it can outweigh millions, if not billions, of suns. According to new research, published in The ...

Ring galaxies and polar-ring galaxies offer natural laboratories for investigating how dynamical processes shape star formation. In collisional ring systems, a near head-on encounter launches a ...

New supercomputer simulations suggest the Milky Way could be surrounded by dozens more faint, undetected satellite galaxies—up to 100 more than we currently know. These elusive "orphan" galaxies have ...

In an unprecedented leap forward in our understanding of the universe’s origins, NASA’s James Webb Space Telescope (JWST) has potentially identified the earliest galaxy ever observed. This galaxy ...
