September’s night sky is putting on one of its best shows of the year, and you do not need a telescope for most of it. The month features brilliant Venus at its best, the Milky Way’s hazy core overhead, and…
Earth’s climate may carry the fingerprints of a journey we barely notice: the Sun’s slow orbit around the center of the Milky Way. New NASA-funded studies suggest our planet’s climate has been influenced by both the Sun’s travels through dense…
NASA and SpaceX have delayed the Crew-13 mission to the International Space Station after engineers found an oxidizer leak in the Dragon spacecraft’s propulsion system during prelaunch preparations. The issue was discovered during routine checkout, and teams are investigating before…
The universe is running out of stars, but maybe not for the reason astronomers thought. Star formation across the cosmos has fallen dramatically over the past 4.5 billion years, and a new study has uncovered a surprising twist: the supply…
For decades, chemists believed they knew exactly what made nickel such a good catalyst for converting methane. They were wrong, in the most interesting way possible. New research shows that a tiny atomic structure that forms on nickel oxide during…
Artificial intelligence has found something in our DNA that decades of lab work had struggled to pin down: the distinctive sequence signature of a key genetic “switch” — the element that decides whether a gene is turned on or off.…
Condensation is everywhere — in power plants, air conditioners, water-harvesting systems, and the fog on your bathroom mirror. Now scientists have developed an ultrathin coating that could dramatically improve how efficiently heat moves during condensation, by transforming tiny polymer structures…
A magnetar — a neutron star with the most extreme magnetic field known in the universe — has apparently done what no laboratory could: revealed signs of a quantum effect that Werner Heisenberg predicted nearly 90 years ago. Its light…
Mars may be hiding a split personality. New research suggests the Red Planet’s southern interior is hundreds of degrees hotter than its northern half — and may even be partially molten deep below the surface. The finding could rewrite what…
Dark matter hunters may have finally seen something worth losing sleep over. The LUX-ZEPLIN (LZ) experiment — a vat of liquid xenon sitting nearly a mile underground in the former Homestake gold mine in South Dakota — has detected a…
