Astronomers have uncovered clues to a red giant’s chaotic past by detecting subtle stellar vibrations that hint at a long-ago collision and an unexpectedly rapid spin. Astronomers at the University of Hawaiʻi Institute for Astronomy (IfA) have pieced together the turbulent history of a distant red giant by studying the…

The galaxy GHZ2 (white box) was discovered by the James Webb Space Telescope in 2022. Its light had to travel some 13.4 billion years to reach Earth. (Image credit: NASA / ESA / CSA / T. Treu, UCLA / NAOJ / T. Bakx, Nagoya U.) Astronomers using the James Webb…

A colossal star met an unexpected fate when it drifted too close to a supermassive black hole 10 billion light-years away. Instead of exploding as a supernova, the star was torn apart, creating the brightest and most distant black hole flare ever recorded—shining with the power of 10 trillion suns...Read…

Fresh observations of two merging black holes confirm predictions made by Stephen Hawking based on Albert Einstein’s theory. A decade after the first detection of gravitational waves from two merging black holes, the LIGO-Virgo-KAGRA collaboration, including Columbia University astronomer Maximiliano Isi, has captured another signal from a nearly identical cosmic…

Space The distant universe might be littered with supermassive stars between 1000 and 10,000 times the mass of the sun, which could solve a cosmic mystery about the origins of extremely large black holes By Leah Crane Facebook / Meta Twitter / X icon Linkedin Reddit Email Artist’s impression of…

Friday 21 November 2025 2:08 pm Wealthy individuals are at risk of tax raid Wealthy Brits are at risk of being slapped with higher taxes in the upcoming Autumn Budget as they fail to understand how to use their tax allowances. The Treasury is scrambling to fill an estimated £20bn…

Encouraged by successes in understanding black holes, theoretical physicists are applying what they’ve learned to whole universes. What they’re finding has them questioning fundamental assumptions about how physics ought to be done. Kristina Armitage/Quanta Magazine Introduction Tinkering at their desks with the mathematics of quantum space and time, physicists have…
