A new study suggests that some of the Universe’s earliest giant galaxies may have lived dramatic lives. They began as dusty ...

Astronomers using the James Webb Space Telescope (JWST) have uncovered a massive stellar bar in a distant galaxy, GN20, seen ...

Astronomers using the James Webb Space Telescope (JWST) have discovered a stellar bar in GN20, a massive galaxy seen just 1.5 ...

JWST found a black hole hiding in a galaxy more than 10 billion light-years away from Earth, and used a cosmic magnifying ...

A large protocluster of galaxies that existed 12.6 billion years ago, first discovered with the Subaru Telescope, has been ...

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 findings from a large survey of galaxies suggest that star formation is largely driven by the supply of raw materials, rather than by galactic mergers that trigger sudden bursts of star formation.

At approximately 100,000 light years in diameter, the Milky Way’s vastness and the broader, ever-changing dynamics of the cosmos defy any attempt to fully understand our home galaxy and its history.

Sci-fi tends to paint the edge of our galaxy as a desolate backwater, but in one early galaxy, the galactic rim is the bright, bustling center of activity, and the core is the aging backwater. The ...

The formation and evolution of galaxies are governed by the processes that assemble their mass and regulate the conversion of gas into stars. Over cosmic history, galaxies grow through the accretion ...

The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming ...

Scientists are turning to the beautiful and famous Whirlpool Galaxy to look for areas where stars could eventually be born. By mapping out the presence of particular chemicals, they hope to learn ...
