An international team of astronomers have used the NASA/ESA/CSA James Webb Space Telescope to watch the Jupiter-sized exoplanet WD 1856 b transit its host star, measuring the planet’s mass and temperature and even detecting its atmosphere. They found that the planet is significantly warmer than expected and determined how it most likely reached its very tight orbit around the star, a white dwarf. The results are our first window into the future of planets like Jupiter after the death of the Sun, billions of years into the future.
