Observations of ultra-massive galaxies, each containing more than 100 billion stars, show that less than 2 billion years ...

Using data from the James Webb Space Telescope, astronomers traced how Milky Way–like galaxies formed and changed over time.

The rate of star formation in the universe has dropped to just 3 percent of its long-ago peak, and there's no end in sight to the decline, a new study finds. A team of astronomers has determined that ...

Astronomers found a young galaxy cluster with unexpectedly hot gas, suggesting cosmic structures formed faster than once ...

In a groundbreaking discovery, a team of researchers has identified a new astronomical object named Cloud-9, which may significantly enhance our understanding of galaxy formation and the early ...

For the first time ever, scientists detect snow-like ice in deep space, surrounding a newborn planetary system and reshaping theories of planet formation.

A team of researchers at the Institute of Astrophysics of the Canary Islands (IAC) has created a new simulation of early galaxy formation. The simulation allows us to get a fascinating, albeit brief ...

The Wolfe Disk, a massive rotating disk galaxy in the early universe, was discovered in 2017 when a stargazing project in the Chilean desert examined light from a distant quasar (top left) absorbed in ...

Among the most fundamental questions in astronomy is: How did the first stars and galaxies form? NASA’s James Webb Space Telescope is already providing new insights into this question. One of the ...
