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

A small red dwarf star, TOI-6894, is defying astronomers' expectations by having a gas giant planet in its orbit.

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

Star TOI-6894 is just like many in our galaxy, a small red dwarf, and only ~20% of the mass of our sun. Like many small stars ...

A giant conundrum has been found orbiting a teeny tiny red dwarf star just a fifth of the size of the Sun. Such small stars ...
