Astronomers have discovered a surprisingly "pristine" red giant with the lowest concentration of heavy elements ever seen in a star. It is likely a direct descendant of one of the universe's first ...

Pulsars could be helping scientists distinguish between gravitational waves caused by supermassive black hole collisions and ...

Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These ...

A team of astronomers claims it has observed the birth of an unusual cosmic object. In an observation of a gamma-ray captured in 2023, they believe they have detected a signal that is comparable to ...

A black hole unlike any seen before has been spotted in the early universe. It’s huge and appears to be essentially on its own, with few stars circling it. The object, which may represent a whole new ...

Chad Hanna receives funding from the National Science Foundation. Scientists first detected ripples in space known as gravitational waves from the merger of two black holes in September 2015. This ...

Artist’s conception of a supermassive black hole, billions of times more massive than the sun, like those found at the centers of galaxies. The black hole’s rapid spin and powerful magnetic fields can ...

In a new study, scientists at the University of Missouri looked deep into the universe and found something unexpected. Using infrared images taken from NASA’s powerful James Webb Space Telescope (JWST ...

Due to the lapse in federal government funding, NASA is not updating this website. This series of 41 radar images obtained by the Deep Space Network's Goldstone Solar System Radar on July 28, 2025, ...

Two colossal black holes slammed together in deep space, creating a final monster that defies current theories. Scientists say it’s the most massive and fastest-spinning merger ever detected. Credit: ...

A weird type of galaxy seen in the early universe has now been spotted in a more recent part of the cosmos, raising questions about their true nature. Over the past few years, astronomers using the ...
