The Universe reveals hidden objects when gravity acts like a giant magnifying glass. Observatories at the cutting edge of technology — like the James Webb Space Telescope (JWST) — can harness these ...

From a serendipitous discovery made with LBT, a team of astronomers led by Arjen van der Wel from the Max Planck Institute for Astronomy (MPIA) has found the most distant gravitational lens yet — a ...

Future missions will be able to find signatures of violating the parity-symmetry in the cosmic microwave background polarization more accurately after a pair of researchers has managed to take into ...

Three physicists have proposed a technique for detecting pairs of supermassive black holes that have so far eluded every ...

Decades after it became clear that the visible Universe is built on a framework of dark matter, we still don’t know what dark matter actually is. On large scales, a variety of evidence points toward ...
