How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 ...

There were lots of ideas about what we might see, but the Universe is full of surprises. One of the first surprises was the ...

Astrophysicists think that black hole masses are hierarchical. The largest are supermassive black holes (SMBH) like the one ...

There is a place in the universe where the ordinary rules simply stop working. Time slows to a crawl. Space curves back on ...

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 ...

Clumps and clusters of galaxies exhibit gravitational effects on the light-and-matter behind them due to the effects of weak gravitational lensing. In addition, arcs, multiple images of the same ...

While the idea of dark matter was originally proposed to explain the structure of galaxies, one of its great successes was explaining the nature of the Universe itself. Features of the Cosmic ...
