An old galaxy reveals clusters of young stars that have formed in an unusually synchronized fashion, challenging the idea ...

An international collaboration of radio astronomers has found evidence suggesting that massive stars might not form as models ...

The James Webb Space Telescope may have found dozens of elusive brown dwarfs — strange objects larger than planets but smaller than stars — beyond the Milky Way for the first time ever.

When star clusters form, near collisions of the closely packed and crisscross moving newborn stars may result in the ejection of stars out of the young cluster. The astronomers, led by UvA Ph.D ...

The galaxies we observe today grow via two main mechanisms: either they pull in, or accrete, gas to form new stars, or they grow by merging with smaller galaxies. Whether different mechanisms were ...

"This information will help us fill in the gaps in our knowledge of how brown dwarfs form and their relationship to stars and planets." Using the James Webb Space Telescope, astronomers have ...

Planet-forming disks around stars naturally fade away over time. Some of the disk falls onto the star and some is heated up by X-ray and ultraviolet radiation from the star and evaporates in a ...
