Black Hole

Black holes are enigmatic yet simplistic astronomical forces at the center of science fiction and scientific discovery alike. At the center of our galaxy, a supermassive black hole with a mass equivalent to 4 million suns lies: Sagittarius A. Though humans – at least to our knowledge – have never…

Scientists from the University of Sheffield have made groundbreaking progress in understanding black holes, time, and dark energy—mysteries that shape our universe. With their immense gravitational pull that traps even light, black holes have fascinated scientists and storytellers for decades. Traditionally, black holes are thought to have a singularity at…

Prepare to be wowed by the mysterious cosmic wonders that are black holes. Black holes are perhaps the most nightmarishly fascinating features of our universe. Like long dark tunnels to nowhere (or giant garbage disposals), these mysterious fixtures in space exert a gravitational pull so gripping that nothing close by…

8m Contains distressing content. Across the UK, hospices are struggling, with many forced to cut staff and services as the sector faces the most challenging time in its history. UK hospices care for 300,000 people each year. It costs £1.8 billion a year to run them. More than £1.3 billion…

When Lior Shamir, a scientist at Kansas State University, examined images from the James Webb Space Telescope Advanced Deep Extragalactic Survey (JADES), he saw something quite unexpected. The majority of the 263 galaxies he observed rotated in the same direction — with two thirds spinning clockwise, Shamir reported in the…

Since its launch on March 12, 2015, NASA’s MMS, or Magnetospheric Multiscale, mission has been rewriting our understanding of a key physical process that is important across the universe, from black holes to the Sun to Earth's protective magnetic field. This process, called magnetic reconnection, occurs when magnetic field lines…

Black holes may transition into white holes, ejecting matter and even time back into the Universe, according to a new study by physicists from the University of Sheffield and the Universidad Complutense de Madrid. Steffen Gielen & Lucía Menéndez-Pidal study the quantum dynamics of a planar black hole, requiring unitarity…

An illustration of "Hawking radiation" leaking out of a black hole. New research into the origins of an incredibly powerful particle detected on Earth could pave the way to proving some of Hawking's major black hole theories correct.
