NASA Hubble telescope tracks dark storms on Neptune behaving oddly NASA calls the storm behavior "surprising." Enlarge Image The Hubble Space Telescope tracked two dark storms on Neptune. The larger one is toward the center top and the smaller one is to the right. NASA, ESA, STScI, M.H. Wong (University of California, Berkeley), and L.A. Sromovsky and P.M. Fry (University of Wisconsin-Madison) We marvel at Mars, puzzle over gases on Venus and stare deeply into Jupiter. NASA and the Hubble Space Telescope are here to remind us there are amazing and mysterious things happening on Neptune, an ice giant with an atmosphere of hydrogen, helium and methane.
