Webb confirms the coldest planet ever found. It's orbiting a white dwarf

In 2020, astronomers detected WD 1856+534 b, a gas giant that orbits a star 81 light-years from Earth. This exoplanet, which is roughly six times the mass of Jupiter (making it a "super-Jupiter"), was the first transiting planet known to orbit a white dwarf (WD) star. In a recent paper, an international team of astronomers describes their observations of this exoplanet using the Mid-Infrared Instrument (MIRI) aboard the James Webb Space Telescope (JWST). Their observation confirmed that WD 1856+...
