Black Hole

Supermassive black holes are found deep within the enormous galaxies at the center of galaxy clusters. The atmospheres of galaxy clusters are packed with plasma and are extremely hot—about 50 million degrees Celsius—but these temperatures typically decrease over time, allowing for the formation of new stars. In a process known…

Astronomers have observed the effect of a distant feeding black hole that is burping out tremendous amounts of energy and blowing huge cosmic bubbles in its surrounding material.  The observations of the galactic cluster MS0735 located 2.6 billion light-years away could reveal new information about mysterious cavities or "radio bubbles"…

Home News Science & Astronomy An illustration of two merging black holes. (Image credit: Mark Myers, ARC Centre of Excellence for Gravitational Wave Discovery (OzGrav)) Black holes are some of the most enigmatic objects in the universe. This is partially because  the equations of general relativity that we use to…

A disk of hot gas swirls around a black hole in this illustration. The stream of gas stretching to the right is what remains of a star that was pulled apart by the black hole. A cloud of hot plasma (gas atoms with their electrons stripped away) above the black…

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…
