NASA Telescopes Detect Signs of Water on Distant 'Warm Neptune'

Scientists using NASA telescopes have detected "a strong water signature" in the atmosphere of a distant Neptune-sized planet, that could help understand more about the birth and development of planetary systems. The study, combining observations from NASA's Hubble and Spitzer space telescopes, shows that the distant planet HAT-P-26b has a primitive atmosphere composed almost entirely of hydrogen and helium. Located about 437 light-years away, HAT-P-26b orbits a star roughly
