Webb telescope tracks HD 80606 b temperature surge (opens in new tab)

NASA’s James Webb Space Telescope observed the exoplanet HD 80606 b as its temperature rose rapidly while its highly elliptical 111-day orbit carried it close to a Sun-like star, according to preliminary findings presented at the 248th meeting of the American Astronomical Society in Pasadena, California. The gas giant has about four times Jupiter’s mass, and its temperature rose by 1,100 degrees Fahrenheit, or about 610 degrees Celsius, during its closest approach. Researchers used Webb’s Mid...
