Last month, we got the exciting news of a rare flash of light on Jupiter, bright enough to be seen through telescopes. According to a new analysis, the cause of this smash was a small asteroid, with a density consistent with meteors that are equal parts stone and iron. The meteor exploded in Jupiter’s upper

The US President has tweeted an American spy satellite image. After some sleuthing, astronomers were able to figure out which satellite it came from: a (formerly) top-secret satellite called USA 224, an optical reconnaissance satellite. Trump’s tweet unwittingly revealed some of the capabilities of American satellite imagery. USA 224 has been kept top-secret for national security

It’s called the Palaeocene–Eocene Thermal Maximum (PETM): a monumental and mysterious global warming event that scientists have never been able to fully explain. Well over 50 million years ago, this epic climate abnormality produced a massive injection of carbon into the atmosphere. The build-up lasted some 20,000 years, and sent global temperatures soaring by as

Last Wednesday, a gravitational wave detection gave astronomers quite the surprise. As researchers were going about their work at the Laser Interferometer Gravitational-Wave Observatory (LIGO), a pair of gravitational waves rolled in just minutes apart. The first, labelled S190828j, was picked up by all three of LIGO’s gravitational wave detectors at 06:34 am, coordinated universal time. The

Here’s a simple how-to on how to construct a traversable cosmic wormhole that could send your spaceship to the furthest reaches of space: take two charged black holes, place them back to back, and thread two cosmic strings through both. Stretch both strings to infinity and presto! You’ve got yourself a traversable wormhole. Confused yet?

After what SpaceX’s founder Elon Musk called an “embarrassing” glitch with Starhopper, an experimental rocket ship, the company pulled off an impressive launch and landing on Tuesday. “Congrats SpaceX team!!” Musk tweeted shortly after the attempt. “One day Starship will land on the rusty sands of Mars.” Starhopper is a roughly 60-foot-tall (18 meters) vehicle
