Microbes blasted off a planet by an asteroid strike may survive the journey to another world, including Earth, according to a ...

Planetesimals are among the first solid bodies to form as dust and pebble-sized material clumps together under gravity. Much like snowflakes compressed into a snowball, they are loose aggregates ...

These peculiar celestial 'snowmen' are found in the Kuiper Belt, a vast expanse beyond Neptune, which is filled with icy remnants dating back to the solar system's formation. The region lies beyond ...

Interstellar comet 3I/ATLAS has steadily been making its exit ever since it had a rendezvous at the end of October with the sun.

Remember 3I/ATLAS? Yes, the interstellar comet that made plenty of headlines in 2025 is still romping through our solar ...

Far beyond Neptune, in the frozen depths of the Kuiper Belt, many ancient objects oddly resemble giant snowmen made of ice and rock. For years, scientists wondered how these delicate two-lobed shapes ...

Researchers simulated how gravitational collapse forms two-lobed contact binaries in the Kuiper Belt without destructive collisions.

Astronomers had decent guesses about how these peanut-shaped asteroids formed but couldn’t get the physics to work—until now.

On November 1, 2023, NASA's Lucy spacecraft, en route to Jupiter's Trojan asteroids, flew by asteroid Dinkinesh and made a ...
