Researchers have used some of the most detailed simulations yet of the early universe to investigate how the first stars and galaxies formed. Led by researchers at the University of Bath in the U.K.,

Look up at the sky on a clear night, and you'll see thousands of stars – about 6,000 or so. But that's only a tiny fraction of all the stars out there. The rest are too far away for us to see them. Yet astronomers like me have figured out how to estimate ...

Astronomers using Georgia State University's Center for High Angular Resolution Astronomy (CHARA) Array have found that nearby stars darken toward their edges more strongly at near-infrared wavelengths than predicted by several widely used models of stellar atmospheres,

Supermassive black holes are ravenous. Clumps of dust and gas are prone to being disrupted by the turbulence and radiation when they are pulled too close. So why are some of them orbiting on the edge of the Milky Way’s own supermassive monster, Sgr A*?

There’s a new contender for the universe’s earliest first-generation stars. A bright clump seen about 450 million years after the Big Bang has the chemical hallmarks of first-generation stars — notably that it appears to have no elements heavier than ...

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 strange chemical fingerprints found in ancient globular ...

Every night before bedtime, I take my dogs outside to do their doggy business, letting them run around in the yard on the eastern side of my house. I live under very dark skies in rural Virginia, and even though I’m a card-carrying astronomer, it’s ...

Social media users have claimed that because stars are not routinely visible in photographs taken from spacecraft, space itself is a hoax. The claim surfaced online following the launch of the Artemis I mission to orbit the Moon, with the spacecraft due to ...

The Stars have been without key forward Matt Duchene this entire season so far due to injury. Now, the Stars have provided an update on Duchene, and it is undoubtedly bad news. On Monday, Stars general manager Jim Nill announced that Duchene will be out for the next three months after undergoing surgery to repair a core injury.
