Exoplanets are key targets in observational astronomy, as they help better understand how planetary systems form, including our own. While thousands have been detected indirectly, obtaining images of ...

Despite being covered in impact craters that could potentially send pieces of the planet into space, we have never found a piece of Mercury. Until, just maybe, now.

Astronomers confirm TOI-5573 b, a rare, miniature Saturn-like planet orbiting a small star, challenging theories of planetary formation.

Some scientists hypothesize that a mysterious, gigantic 9th planet may be lurking at our solar system’s edge. Why haven't we seen it yet?

The paper presents China's development of a massive, data-driven monitoring system capable of capturing real-time environmental dynamics across space, air, ground, and sea.

This new dwarf planet may exist at the edge of the solar system, possibly disproving Planet Nine's existence. This is the story of that newly encountered planet.

A possible dwarf planet, like Pluto, has been observed in our solar system, according to a preprint published in arXiv. The area of space where this planet was found was previously thought empty.
