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 ...

In the distant reaches of the solar system are many icy objects that resemble snowmen. Now, a new study reveals the simple ...

Astronomers might have found evidence of a structure located farbeyond Neptune, potentially giving us clues about the solar system’s primordial past. This discovery involves a dense concentration of ...

“Comet 3I/ATLAS was full-on erupting into space in December 2025, after its close flyby of the Sun, causing it to significantly brighten,” said Johns Hopkins astronomer Carey Lisse, lead author of a ...

If you travel far enough away from the Sun, the Solar System becomes a lot more populated. Out past the orbit of Neptune lies the Kuiper Belt, a vast, ring-shaped field of icy rocks. This is where ...

Samples from Ryugu, a small, near-Earth asteroid, preserve natural remanent magnetization (NRM) from the early history of the solar system. However, despite multiple studies, there is currently no ...

Moons may seem like quiet companions to the planets, but many of them are worlds every bit as fascinating as the planets themselves. Some are covered in oceans, some erupt with lava, and others hide ...

Microscopic crystals extracted from meteorites could help settle a debate about the birth of our patch of the Milky Way.

The Oort cloud is traditionally thought of as a vast shell of perhaps trillions of icy objects encasing our solar system, serving as the final boundary between us and the dark reaches of interstellar ...
