Indian astronomers find TOI-5205 b, Jupiter-size planet defying theories
Indian astronomers just found a wild new planet, TOI-5205 b, that's shaking up what we thought we knew about how planets form.
It's as big as Jupiter but orbits a tiny star, about 40% the mass of our sun, which isn't supposed to happen according to current theories.
This discovery, part of the GEMS Survey, was published in The Astronomical Journal.
JWST finds low carbon and oxygen
Using the James Webb Space Telescope, scientists found that this planet's atmosphere has way less carbon and oxygen than expected, very different from its star and other gas giants.
They also spotted methane and hydrogen sulfide as the planet blocked 6% of its star's light during transit.
All these odd features suggest there's still a lot to learn about how weird and diverse planets can be, especially around small stars.
