The interstellar comet 3I/ATLAS is leaving our solar system for good. Here's what to know about its journey and NASA's observations.

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.

Astronomers have puzzled for years over a strange pattern in the outer solar system. A surprising number of icy bodies far beyond Neptune resemble snowmen, made of two rounded lobes stuck together.

Early last year, asteroid 2024 YR4 caught the public’s attention as its chances of hitting Earth in the near future climbed to 3.1 percent. This was the highest probability of a strike by an object of ...

Plenty of asteroids can survive their fiery plunge through the Earth’s atmosphere. If they’re big enough, they can prove incredibly destructive, like the 60-foot Chelyabinsk meteor that exploded over ...

A hopeful pup watches as a delivery driver leaves without stopping, leaving viewers sympathizing with the dog’s disappointed reaction.

Armageddon might not have a reputation as a scientifically accurate film. But scientists now say the Hollywood blockbuster got one thing right - we really could nuke an asteroid if it were heading for ...

Could humanity nuke an incoming asteroid to deflect it and save the Earth, disaster-movie style? A unique new impact simulation suggests that a nuclear option could be a viable last resort to avert an ...

This time last year, the world was gripped by reports that an incoming, nearly 200-feet-wide asteroid had a tiny, tiny chance of hitting the Earth in 2032. The sigh of relief that we weren’t on course ...
