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

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

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