A few years ago, astronomers discovered an exoplanet orbiting the white dwarf 1856+534 b. Now they've used the mighty JWST to do follow-up observations and made some exciting discoveries. It's definitely a planet and not a brown dwarf, with a temperature of 186 K (-87C/-125F) and about 6 times the mass of Jupiter. This makes it the coldest exoplanet ever detected, and it's orbiting in the "forbidden zone," which should have been engulfed during the red giant phase.
