7 results for "cosmic events"
Astronomers detected an unprecedented gamma-ray burst lasting seven hours—the longest ever recorded—and now believe it came from a black hole devouring a helium star. The discovery could help scientists spot similar cosmic events in the future.
Astronomers have more than doubled their catalog of gravitational waves, detecting 218 cosmic events from colliding black holes and neutron stars across the universe. These spacetime ripples are revealing secrets about how massive celestial objects form and evolve, opening an entirely new way to study the cosmos.
Astronomers discovered neutron stars colliding in one of the smallest, faintest galaxies ever observed, solving a decades-old mystery about gamma-ray bursts. The finding shows that universe-shaking cosmic events happen in places we never thought to look.
NASA discovered two ultradense neutron stars colliding in a tiny galaxy hidden inside a massive gas stream, solving puzzles about mysterious gamma-ray bursts and how precious metals end up in distant stars. This groundbreaking find shows extreme cosmic events can happen in the smallest places.
A revolutionary telescope just started sending scientists 800,000 nightly alerts about changes in the universe, from exploding stars to new asteroids. Within a year, it will capture more cosmic objects than all other observatories combined throughout human history.
China's new satellite network is running artificial intelligence models in space to tackle real-world challenges from mapping infrastructure to tracking cosmic events. After nine months of testing, the system is proving that space-based AI can deliver faster, smarter solutions back to Earth.
Astronomers captured the exact moment a distant star unleashed a superflare, releasing months of our sun's energy in seconds. This breakthrough observation helps scientists understand these powerful cosmic events and predict how they affect planets.
