Engineers at a deep underground research facility noticed something strange during major rainstorms: airflow underground sometimes reversed direction. Using new sensors and mathematical modeling, they found that water rushing down a shaft was ...

Scientists are calling for a lunar quarantine facility where samples from Mars, the Moon, and beyond would be examined before being brought to Earth. They warn that even a tiny alien microorganism could have unpredictable effects on Earth's ...

A strange "chirping" signal from a distant supernova has revealed the birth of a magnetar, confirming that these incredibly magnetic neutron stars can power the universe's brightest stellar explosions. The discovery also marks the first time Einstein ...

Quantum mechanics has journeyed from a strange and controversial idea to the foundation of some of humanity's most advanced technologies. Now researchers are pushing its boundaries even further, with potential breakthroughs in energy, medicine, ...

NASA's Hubble Space Telescope has captured a spectacular red, white, and blue view of one of the Milky Way's oldest star clusters to celebrate the nation's 250th anniversary. Hidden within the ancient cluster are clues to how exploding stars helped . ...

Hubble has captured a spectacular view of LH 95, where about 2,500 young stars are still on their journey to becoming full-fledged stars. Scientists discovered these growing stars can keep pulling in gas and dust for millions of years, extending an . ...

Celebrating the United States' 250th anniversary, NASA released a stunning Hubble portrait of Messier 3, an ancient globular cluster with more than 500,000 stars. The remarkable cluster is helping scientists unravel the Milky Way's past thanks to its ...

Researchers have proposed that black holes stop evaporating at the last moment, leaving behind tiny remnants that preserve all the information they contain. The same seven-dimensional geometry behind this idea could also help explain why elementary . ...

NASA is marking the United States' 250th birthday with four striking red, white, and blue images of deep space from the Chandra X-ray Observatory. The collection features an exploded star, a stellar nursery, a galaxy where stars are rapidly forming, ...

Physicists have developed a new optical centrifuge that can precisely spin molecules inside a superfluid for the first time. The advance could help unravel some of the biggest mysteries of quantum liquids and reveal how superfluidity breaks down at . ...
