Astronomers are living in a golden age of bigger and better telescopes. But even our most advanced technology pales in comparison to the power of nature’s own “cosmic magnifying glasses” – strong ...

Maunakea, Hawai’i – Astronomers have captured a bizarre image of a supernova, the powerful explosion of a star, whose light was so warped by the gravity of a galaxy that it appears as multiple images ...

When a gravitational lens magnifies a background galaxy, why don't we see the object doing the lensing, as we would if looking through an optical lens? Robert Hertrick Pittsburgh Gravitational lensing ...

Peering into deep space, NASA's James Webb Space Telescope has helped astronomers find places to study gravitational lensing, an effect in which massive objects such as galaxies warp space-time itself ...

A new image from the Hubble Space Telescope reveals the funny things that galaxies can achieve when they huddle together. When galaxies are far enough away, the 33-year old observatory gets a sort of ...

Astronomers just found another case of something out there bigger than a supermassive black hole: ultramassive black holes, which are the true behemoths of the Universe, clocking in at over 10 billion ...

A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...
