Scientists have discovered a few thousand planetary nebulas in the Milky Way. Those include the Ring Nebula, aka NGC 6720 and Messier 57. With Webb, the researchers could see a compact dust cloud ...

Researchers found the object named 2017 OF201 while searching for "Planet Nine" - a hypothetical planet thought to exist ...

For the dwarf planet candidate, one trip around the sun takes over 24,000 years. Its orbit challenges a proposed path for a hypothetical Planet Nine.

James Webb Space Telescope observations suggest Pluto’s atmosphere is unlike any other in the solar system, confirming a 2017 ...

The discovery of a Saturn-sized gas giant orbiting a small red dwarf is urging astronomers to reconsider their theories of ...

A newly discovered gas giant, called TOI-6894b, orbiting a low-mass red dwarf star defies existing models of planet formation ...

TOI-6894 is one such star. Announced Wednesday in a paper for Nature Astronomy, the red dwarf is just 20% the mass of our Sun ...

Astronomers have been left puzzled by the discovery of an unusually large planet orbiting a remarkably small star, a cosmic ...

Astronomers have spotted a cosmic mismatch that has left them perplexed - a really big planet orbiting a really small star.

The host star, TOI-6894, is a red dwarf with only 20% the mass of the Sun, typical of the most common stars in our galaxy.

Giant planets are not rare per se — after all, we have four in our own solar system. Such large worlds are, however, rarely ...

Scientists have discovered a giant planet called TOI-6894b, orbiting a star that should be far too small to have formed it. The discovery could further challenge theories of planet formation.
