Neutron scans of the "Black Beauty" meteorite reveal ancient Martian water, uncovering hydrogen-rich clasts that constitute 11% of the total water content. Advanced scanning technologies help identify iron, titanium, and organic components, providing evidence of early Mars' liquid surface water.
NWA 7034 is a masterpiece of Martian geology. New CT scanning technology allows us to look inside this 4.48-billion-year-old rock without crushing a single grain.
Historically, studying meteorites meant destroying them—cutting, crushing, or dissolving samples to unlock their secrets. But a new paper by Estrid Naver (Technical University of Denmark) demonstrates a better way.
A black hole shredded a star years ago. But instead of fading, it's been "burping" out a radio jet that is growing exponentially brighter.
Normally, when a black hole eats a star (a Tidal Disruption Event), it's a flash in the pan. The star gets shredded, flares up, and fades away.
Using TESS and Swift data, astronomers have detected rare, rhythmic pulses in the chaotic jets of distant galaxies. Blazars are the monsters of the universe: supermassive black holes shooting jets of plasma directly at Earth at nearly the speed of light. They are usually chaotic and unpredictable.
