NASA’s Lucy Reveals Wobbling, Peanut-Shaped Asteroid

Even small asteroids lead complex lives. During its flyby of the asteroid Donaldjohanson last year, NASA’s Lucy spacecraft revealed the asteroid to be a wobbly, peanut-shaped body that has undergone a lot of activity in its relatively short history.

NASA’s Curiosity Finds Organic Molecules Never Seen Before on Mars

After years of lab work, the results are in: A rock that NASA’s Curiosity Mars rover drilled and analyzed in 2020 includes the most diverse collection of organic molecules ever found on the Red Planet. Of the 21 carbon-containing molecules identified in the sample, seven of them were detected for the first time on Mars. […]

NASA’s Hubble Detects First-Ever Spin Reversal of Tiny Comet

Astronomers using NASA’s Hubble Space Telescope have found evidence that the spinning of a small comet slowed and then reversed its direction of rotation, offering a dramatic example of how volatile activity can affect the spin and physical evolution of small bodies in the solar system. This is the first time researchers have observed evidence […]

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 […]
