Black Hole

Astrophysicists have devised a new way to verify the existence of the supermassive black hole Leo I*. A behemoth black hole, as massive as the one at the center of the Milky Way, is hosted by a dwarf galaxy less than 1 million light-years away. Invisible so far — maybe…

Astronomers using the Event Horizon Telescope released a picture in May of Sagittarius A*, the black hole at the centre of the Milky Way Space 22 December 2022 By Leah Crane This is the first image of the supermassive black hole at the centre of our galaxy EHT Collaboration It…

Black holes are among the most intriguing phenomena in our universe. From the pictures of our galaxy’s black hole, to attempts to learn more about how they form and even what happens when two black holes merge, scientists have pushed our knowledge of these celestial entities further than ever. Now,…

A star getting too close to a massive black hole (MBH) can get disrupted by the tidal forces in a tidal disruption event (TDE). The first observational evidence for TDEs came from detecting X-ray flares from the centers of quiescent galaxies in 1990-1991. Recently, multiple NASA telescopes observed a massive…

Warning: the following article contains disturbing content. It took a little over a year for Robert Sudy to realise the pseudo-law movement he had been a part of - which shared similar ideas about legal rights with the sovereign citizen movement in the US - was futile. “I was being…

By using fluids to model inaccessible realms of the cosmos, Silke Weinfurtner is “looking for a deeper truth beyond one system.” But what can such experiments teach us? In her lab at the University of Nottingham, Silke Weinfurtner creates analogues of black holes in “a giant bathtub, but it’s a…

        | Published: Sunday, December 11, 2022, 7:20 Astronomers have detected a massive galactic explosion, and they believe it is a result of a black hole's collision with a star. The blast named GRB 211211A lasted for around 50 seconds and spewed copious gamma rays in a…

Clues to a black hole's origins can be found in the way it spins. This is especially true for binaries, in which two black holes circle close together before merging. The spin and tilt of the respective black holes just before they merge can reveal whether the invisible giants arose…

Dear DM168 readers, On 17 October one of the members of South Africa’s judiciary stuck his neck out and in a judgement warned of alleged police corruption linked to hitmen, the taxi industry and gangsters in the Western Cape. Judge Daniel Thulare’s unprecedented judgment, delivered in the Western Cape high…

Astronomers have spotted a strange blast of gamma radiation from space that defies categorisation, and it may mean a gap in our understanding of how black holes form Space 7 December 2022 By Leah Crane Gamma ray bursts blast radiation into space NASA/Swift/Cruz deWilde A strange blast of radiation from…
