Surprisingly Hubble Telescope Watches Neptune's Dark Storm Die For the first time, NASA's Hubble Space Telescope has captured time-lapse images of a large, dark storm on Neptune shrinking out of existence. A recent Hubble program called Outer Planets Atmosphere Legacy, or OPAL, provides yearly global maps of our gas giant planets, allowing planetary scientists to view changes in formations such as Neptune's dark storms.
