News

Milky Way’s supermassive black hole shines in stunning first portrait

12 May 2022 Keith Cooper

The black hole in the centre of our Milky Way Galaxy has been imaged for the first time, showing a ring of gas encircling the event horizon, beyond which no light can escape.

News

Supermassive black hole ‘spaghettifies’ doomed star in tidal disruption event

12 October 2020 Astronomy Now

Catching a tidal disruption event early allowed astronomers to follow along as a supermassive black hole devoured a passing star.

News

Gravitational wave observatories detect biggest black hole merger yet

2 September 2020 Astronomy Now

Gravity waves indicate the birth of an elusive intermediate-mass black hole, raising fresh questions about the gap between stellar and supermassive black holes.

News

Astronomers find dual quasars are exceedingly rare

1 September 2020 Astronomy Now

While galaxy collisions and mergers are not rare, merging supermassive black holes at the hearts of active galaxies are far less common.

News

A galactic train wreck with three supermassive black holes

23 November 2019 Astronomy Now

A third supermassive black hole has been found near the heart of an ongoing collision of three massive galaxies 300 million light years from Earth.

News

Dust-choked doughnut detected around gargantuan black hole

5 April 2019 Astronomy Now

Astronomers have made the first direct observation of a dust-choked torus surrounding a supermassive black hole powering an active galactic nucleus.

News

Seeing matter sucked into a black hole at 30 percent lightspeed

20 September 2018 Astronomy Now

For the first time, astronomers have observed dust being sucked directly into a supermassive black hole, evidence of “chaotic accretion” that may have helped supermassive holes rapidly gain mass in the early universe.

News

Most distant radio galaxy, host to a voracious black hole, is found

7 August 2018 Astronomy Now

Astronomers have detected the most distant known radio galaxy, a surprising discovery given the supermassive black hole powering the galaxy was actively accreting gas and dust when the Universe was in its infancy.

News

Epic campaign confirms relativity near supermassive black hole

26 July 2018 Astronomy Now

Astronomers tracking a star passing close to the supermassive black hole at the heart of the Milky Way have detected relativistic gravitational redshift in light reaching Earth.

News

Dust clouds may explain emissions from active galactic nuclei

18 June 2018 Astronomy Now

Changes in the light emerging from active galactic nuclei, powered by supermassive black holes, may be explained by clouds of intervening dust that can dim and redden the radiation, eliminating the need for more exotic explanations.
