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

Caltech simulations reveal what happens when black holes collide with neutron stars—violent cracking, intense shock waves, ...

Astronomers detect 10 billion-year-old radio waves from a distant galaxy cluster SpARCS1049, revealing a mini-halo that ...

In a recently published paper in Physical Review Letters, scientists propose a comprehensive theoretical framework indicating ...

A groundbreaking simulation reveals how neutron star mergers forge black holes, generate gamma-ray bursts, and scatter gold ...

Collisions Near the Event Horizon. When matter gets very close to a fast-spinning black hole, especially if it moves opposite to the black hole’s spin, strange things happen.

A new census reveals that 35% of supermassive black holes are hidden behind dust, disrupting major galactic models.

The findings suggest black holes could provide a cheaper, natural alternative to billion-dollar particle colliders, if we can figure out how to harness them.

A spinning disk and a smartphone are all that are needed for students to study vibrations analogous to those produced by the ...

Astronomers have spotted a supermassive black hole ripping apart and devouring a star in colliding galaxies. It is only the second time a tidal disruption event has been seen in interacting galaxies.

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 ...

A new paper claims astronomers discovered an ultramassive black hole heavier than any other black hole we've ever measured.
