Water, unexpected chill detected on distant giant planet

Using the James Webb Space Telescope, a University of Maryland-led team detected water, methane and ammonia in the atmosphere of HATS-6 b, a giant planet located 500 light-years from Earth. The study also found that HATS-6 b may be significantly cooler than expected compared to standard calculations of its temperature. Notably, HATS-6 b is roughly the size of Jupiter.
