How astronomers used gravitational lensing, a space-time trick predicted by Einstein, to detect a black hole measuring 30 billion times the mass of the sun.

Gravitational waves stretch and squeeze the fabric of space and time itself. When space/time is squeezed, pulsar pulses ...

These black holes are the most distant and stable objects we know. Using a technique called very long baseline interferometry ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

A newly discovered radio halo, 10 billion light-years away, reveals that galaxy clusters in the early universe were already steeped in high-energy particles. The finding hints at ancient black hole ...

Scientists have discovered the farthest-ever 'mini-halo,' a sea of charged particles around a distant galaxy cluster that ...

LOFAR detects a faint radio 'mini-halo' from 3.8 billion years ago, revealing how galaxy clusters evolved in the early ...

One of the most perplexing discoveries in modern astronomy has been finding supermassive black holes, some weighing billions ...

Under the right conditions, this collapse doesn’t end in a singularity — instead, it bounces and begins expanding again,” said University of Portsmouth professor Enrique Gaztañaga in a statement that ...

A cloud of high-energy particles surrounding a distant galaxy cluster offers a rare glimpse into the forces shaping the early ...
