[00:00:00]TOI 2031b a hot Jupiter 460 light years away just changed everything.

[00:00:05]Astronomers studying TOI 2031b found five things that don't match Jupiter, Saturn, or any textbook. Number five, it's bloated. TOI 2031b has Jupiter's mass but 50% more radius. Its atmosphere is puffed like [music] a balloon from tidal heating. Number four, it orbits at scorching distance, just 0.040 from its K dwarf star, 12 times closer than Mercury to the Sun. Number three, but here's where models break. Its density is 0.4 g per cc, lighter than cork.
