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

With its low density and unusually cool, methane-rich atmosphere, this planet offers a rare window into giant planet formation around small stars.

It had not been thought possible that such tiny, weak stars could provide the conditions needed to form and host huge planets.

Astronomers discover giant gas planet TOI-6894b orbiting a tiny red dwarf, rewriting what we know about planet formation.

Screening can now determine their risk for an ever-growing list of conditions — including ones we can’t do much about.

Scientists have discovered a giant planet called TOI-6894b, orbiting a star that should be far too small to have formed it.
