Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a ...

Our solar system is much like a trail of microcosmic breadcrumbs: Follow the molecular bits as far back as they go, and you'll learn a thing or two about where many of our planets and other celestial ...

In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the ...

Nearby red dwarfs are turning into rich laboratories for studying small rocky worlds. One such star now stands out as a system with four or more planets, including at least one in the habitable zone ...

A new model that incorporates data gathered by the JWST could help scientists understand the composition and mass of objects in the distant Kuiper Belt and beyond.

Ammonite was discovered using the Subaru Telescope in Hawaii, with follow-up confirmation from the Canada-France-Hawaii Telescope. Its orbit and size officially qualify it as a distant dwarf planet.

A new formation theory for Pluto's moon Charon could explain why Pluto is geologically active. Illustration incorporates NASA New Horizons terrain imagery. Pluto — demoted to dwarf planets status in ...
