Scientists using NASA telescopes have detected “a strong water signature” in the atmosphere of a distant Neptune-sized planet, which 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 twice as old as our Sun. The analysis is one of the most detailed studies to date of a “warm Neptune,” or a planet that is Neptune-sized and close to its star.The researchers determined that HAT-P-26b’s atmosphere is relatively clear of clouds and has a strong water signature, although the planet is not a water world.
