In 2013, NASA discovered a bacteria evading its most stringent disinfections. Scientists just figured out how it does it.

Comet C/2025 A6 (Lemmon) is this year’s brightest comet visible from Earth—an icy relic from the solar system’s origins that ...

“Our study shows that there’s a population of potentially dangerous asteroids that we can’t detect with current telescopes,” Valerio Carruba, an astronomer at the UNESP School of Engineering said.

On Oct. 1, 2025, the small asteroid known as 2025 TF whizzed past Earth at a distance of only 266 miles (428 kilometers) from our planet — roughly the same altitude as the International Space Station.

A new analysis estimates that the asteroid belt is steadily losing mass each year, and may not be as permanent a feature of the solar system as we thought. A team of astronomers led by Julio Fernández ...

A small, giraffe-size asteroid called 2025 TF came closer to Earth than some satellites on Wednesday (Oct. 1), stunning astronomers who first spotted it hours later. Measuring an estimated 3.3 to 9.8 ...
