Merger of two massive black holes is one for the record books

arstechnica.com Unknown 2026-01-19 00:30:23

Physicists with the LIGO/Virgo/KAGRA collaboration have detected the gravitational wave signal (dubbed GW231123) of the most massive merger between two black holes yet observed, resulting in a new black hole that is 225 times more massive than our Sun. The results were presented at the Edoardo Amaldi Conference on Gravitational Waves in Glasgow, Scotland. The LIGO/Virgo/KAGRA collaboration searches the universe for gravitational waves produced by the mergers of black holes and neutron stars. LI

Mysterious Signals From Deep Space Hint at Something Brutal, Scientists Say

futurism.com Unknown 2026-01-20 15:15:00

Astronomers believe they've uncovered the source behind mysterious cosmic signals known as fast X-ray transients (FXTs) — and it adds a grim twist to our understanding of the death of stars. Right as a massive star explodes in a supernova, it unleashes a tremendously energetic stream of particles called a jet, producing a gamma ray burst — one of the most powerful explosions in the universe. The rest of the star, typically, collapses into a black hole. But a pair of new studies suggests that t

Nuclear Waste Reprocessing Gains Momentum in the U.S.

The United States’ 90,000-ton stockpile of radioactive nuclear waste has long been a liability, but researchers are increasingly eyeing it as a resource. New techniques in transforming spent fuel, new nuclear fuel cycle directives from the Trump administration, and the doling out of a Biden-era $40 million research program together aim to repurpose nuclear waste on a commercial scale. In a suite of executive orders announced on May 23, U.S. President Donald Trump directed the U.S. Department of

OpenAI May Be in Major Trouble Financially

Since OpenAI unleashed ChatGPT on the world two and a half years ago, the company has operated at a substantial financial loss. Despite raising at least $60.9 billion in private funding since ChatGPT's public launch, OpenAI is leaking billions of dollars every year. In 2024, for example, the tech startup lost some $5 billion, per MSNBC. That doesn't seem to bother OpenAI insiders, though, who hope to be bringing in $125 billion in annual revenue by 2029.

Astronomers have, for the first time, witnessed a star meeting a dramatic end by exploding twice. In a study published in Nature Astronomy, researchers analyzed the centuries-old remains of supernova SNR 0509-67.5 with the European Southern Observatory’s Very Large Telescope, finding the first visual evidence of a star’s “double-detonation.” Most supernovae are the explosive result of massive stars collapsing when they exhaust their nuclear fuel.
