NASA’s Hubble Unexpectedly Catches Comet Breaking Up

In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]

NASA Studies Reveal Hidden Secrets About Interiors of Moon, Vesta

Analyzing gravity data collected by spacecraft orbiting other worlds reveals groundbreaking insights about planetary structures without having to land on the surface. Although the Moon and the asteroid Vesta are very different, two NASA studies use the same technique to reveal new details about the interiors of both.
