Lowell Observatory will be hosting the 2025 I Heart Pluto Festival from Feb. 13 to 17, celebrating the planet and its ...

While Charon is currently listed as a satellite or moon by the International Astronomical Union (IAU), consideration is being given to it perhaps being classified as a dwarf planet in its own right, ...

Using the Atacama Large Millimeter Array, astronomers have discovered icy exocomet belts circling 74 different alien planetary systems.

In addition, the objects in the rings would become smaller and smaller over time due to collisions. In the solar system, the Kuiper Belt is a ring-shaped structure consisting of various large ...

Then, a subsequent impact between Charon and a smaller Kuiper Belt object could have produced the debris that formed the system's four small moons: Nix, Styx, Kerberos and Hydra. Learn about the ...

Arrokoth, located a billion miles beyond Pluto, is one of the coldest places where we've directly measured the temperature.

"It's a pretty big question since a bunch of other large Kuiper Belt Objects also have large moons, so it seems like this is something that happens in the Kuiper Belt with some frequency ...

“And that has pretty big implications for the Kuiper Belt as a whole, because eight of the 10 largest Kuiper Belt objects are similar to Pluto and Charon.” For more on this research, see “Kiss and ...

Of all the mysteries that the massive James Webb Space Telescope has seen so far in the early universe, one of the strangest are objects that astronomers now call "little red dots." Like the ...

Both Pluto and Charon began as independent objects in the Kuiper Belt, a band of icy objects that surrounds our solar system out beyond the orbit of Neptune. View of the proposed kiss-and-capture ...
