On October 9, 2008, the State Space Agency of Ukraine sent a message towards Gliese 581c. Unlike the Voyager records, whose messages were chosen by a committee chaired by renowned physicist Carl Sagan ...

A giant gas planet comparable in size to Saturn exists around a small red dwarf star. The discovery is beyond the scope of conventional astronomy theory, and is making experts reconsider conventional ...

"Dark matter could be captured by stars and accumulate inside them. If that happens, it might also interact with itself and ...

Some of the faintest, coldest stars in the universe may be powered not by fusion—but by the annihilation of dark matter deep within them. These “dark dwarfs” could exist in regions like the galactic ...

NASA's James Webb Space Telescope detection of TWA 7b represents a major milestone: the lightest exoplanet discovered with a direct image.

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.

The assistant did not initially add Pluto, the far-flung dwarf planet companion at the edge of the solar system — or the asteroid belt.

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.
