Black Hole

From 12.01am this morning, Australians can legally no longer be subjected to election ads when they watch television or listen to radio. But the 33-year-old rule requiring traditional media observe three-day pre-election blackouts has never been more redundant thanks to the internet.  The media blackout predates Australia’s adoption of the…

NASA Universe Web Team Apr 30, 2025 Did you know some of the brightest sources of light in the sky come from the regions around black holes in the centers of galaxies? It sounds a little contradictory, but it’s true! They may not look bright to our eyes, but satellites…

Physics A black hole bomb – an idea first proposed in 1969 – has now been realised in the lab as a toy model made from a rotating cylinder and magnetic coils. Studying the bomb could help us better understand real black holes. By Alex Wilkins Facebook / Meta Twitter…

Scientists recently discovered something incredibly rare in space—a lone black hole drifting by itself through our galaxy. This kind of find is so unusual that they say it’s like winning a cosmic lottery. In fact, the chances of spotting such a black hole are said to be “one in a…

Space Unusual signals called quasi periodic eruptions appear to come from black holes, but we don't know what creates them. Now astronomers have seen the most powerful one of these signals ever, and have a new idea about their cause By Alex Wilkins Facebook / Meta Twitter / X icon…

In 2018 astronomers at MIT and elsewhere observed previously unseen behavior from a black hole known as 1ES 1927+654, which is about as massive as a million suns and sits in a galaxy 270 million light-years away. Its corona—a cloud of whirling, white-hot plasma—suddenly disappeared before reassembling months later.  Now…

The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these enigmas, we take what we know about space, time, gravity, and quantum mechanics and apply it…
