Astronomers are living in a golden age of bigger and better telescopes. But even our most advanced technology pales in ...

Ursa Major III/Unions 1 (UMa3/U1), the faintest known satellite of our galaxy, orbits the Milky Way at a distance of more ...

GW190814 did not involve a black hole above the mass limit. Quite the contrary, one of the black holes involved is thought to ...

Jim Bickford is leading the Thin Film Isotope Nuclear Engine Rocket (TFINER) project to develop a system for propelling a ...

The highly competitive projects bring together experts from a range of disciplines to explore promising topics of fundamental ...

A galaxy cluster can have its mass reconstructed from the gravitational lensing data available. Most ... More of the mass is found not inside the individual galaxies, shown as peaks here, but from ...

The new work involves a third way to measure the distance that's independent of the other two. It relies on gravitational lensing, where the distortion in space-time caused by a massive object ...

After reviewing a massive stellar explosion, researchers believe they spotted a never-before-seen type of supernova that ...

But the tiny gravitational ripples, along with our recently acquired ability to see them, ushered in a novel way to study the universe. Gravitational waves offer independent cross-checks on ...
