Scientists have obtained the first image of a black hole, using Event Horizon Telescope observations of the center of the galaxy M87. The image shows a bright ring formed as light bends in the intense gravity around a black hole that is 6.5 billion times more massive than the Sun. This long-sought image provides the strongest evidence to date for the existence of supermassive black holes and opens a new window onto the study of black holes, their event horizons, and gravity.

3 major moments from the ‘golden’ decade of black holes

This artist’s impression shows two tiny but very dense neutron stars at the point at which they merge and explode to produce gravitational waves and a short gamma-ray burst, both of which were observed on Aug. 17. Credit: ESO/L. Calçada/M. Kornmesser

Neutron star collision offers new source of gravitational waves

Astronomers have discovered a collision of neutron stars that released both a stream of gravitational waves and a flash of light, backing one of Einstein's theories.

The collision of two black holes -- a tremendously powerful event that was detected for the first time ever by the Laser Interferometer Gravitational-Wave Observatory, or LIGO -- is seen in this still image from a computer simulation released in Washington February 11, 2016. The discovery marked the first detection of gravitational waves -- ripples in space and time hypothesized by Albert Einstein a century ago.

LIGO gravitational wave discoverers win 2017 Nobel Prize in physics

Rainer Weiss, Barry C. Barish and Kip S. Thorne have won the 2017 Nobel Prize for physics for leading the projects that discovered gravitational waves and proved an century-old Einstein theory.

Artist's conception shows two merging black holes similar to those detected by LIGO. The black holes are spinning in a non-aligned fashion, which means they have different orientations relative to the overall orbital motion of the pair. LIGO found hints that at least one black hole in the system called GW170104 was non-aligned with its orbital motion before it merged with its partner.

‘Dancing’ black holes yield stellar object as massive as 49 suns

Astronomers announced they have detected another gravitational wave tearing through spacetime, changing of our understanding of black holes and other stellar phenomena.
