Black Hole

For about two hours, a bubble of extremely hot electrons whirled around the Milky Way’s supermassive black hole at 30 per cent of the speed of light, and then it was destroyed Space 22 September 2022 By Leah Crane Diagram of the orbit of a bubble of electrons around the…

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have spotted signs of a ‘hot spot’ orbiting Sagittarius A*, the black hole at the centre of our galaxy. The finding helps us better understand the enigmatic and dynamic environment of our supermassive black hole. “We think we’re looking at a hot…

Credit: NSF In 2019, the Event Horizon Telescope collaboration captured the first-ever image of a black hole, and earlier this year, it captured an image of the black hole at the heart of our own Milky Way galaxy. In an article in Natural Sciences, a leading member of the collaboration—Heino…

Deep in the heart of the Milky Way, strange things happen. This is a place where stars slingshot around apparently empty space at an appreciable fraction of the speed of light. Scientists have long thought that only a supermassive black hole could explain the stars' movements, but until this year,…

A black hole with a mass about 10 times that of the sun is thought to be the closest to Earth discovered so far. It is orbited by a star that could host planets, from which the black hole would be visible in the sky Space 16 September 2022 By…

The regional contractor went under last summer after 161 years in business. An update filed at Companies House by liquidate Bishop Fleming shows 196 unsecured creditors have filed claims for £15.25m. The original statement of company affairs originally indicated £8.7m of debts owed to 365 unsecured creditors. The report states…

(Image credit: Shutterstock) In science fiction, space explorers routinely zip through wormholes in space-time that are connected by two black holes — celestial objects so dense that not even light can escape their clutches.  But are black holes really doorways…

Vadim Sadovski/Shutterstock Out in the depths of space there lurk hidden monsters — black holes — which are the densest objects in the universe. They can be hard to spot because they absorb everything which comes too close to them, including light. So we aren't really sure how many of…

Just look at the last months. Look at the rhetoric. What's the chance that we're going to make it through the next 20 years? You have all the nuclear weapons, all the conflicts. But now you have environmental disaster, you have food insecurity, you have wars over water, you have…
