JWST observations show that early galaxies were chaotic, gas-filled systems rather than stable disks. Researchers from ...

A handful of extremely massive stars, each heavier than 1,000 Suns, may have sculpted the chemistry of the oldest star ...

A team of astrophysicists has unveiled how colossal stars thousands of times more massive than the Sun shaped the earliest star clusters and galaxies. These short-lived giants not only forged the ...

Astronomers may have misread cosmic acceleration for 27 years. The universe may be slowing down, not speeding up.

Using the James Webb Space Telescope, astronomers have captured the clearest picture yet of how galaxies formed in the early universe.

At a distance of160,000 light-years, an aging red supergiant star in a neighboring galaxy has become the subject of an ...

A comprehensive set of simulations by Flatiron Institute astrophysicists and their colleagues revealed that magnetic fields are responsible for creating black holes with masses in a range previously ...
