NASA's Hubble captures Neptune's foul-smelling storm as it dies

Washington : NASA's Hubble space telescope has captured Neptune's mysterious dark storm, that probably smells like rotten eggs, shrinking out of existence.

 "It looks like we're capturing the demise of this dark vortex, and it's different from what well-known studies led us to expect," said Michael Wong of the University of California at Berkeley in the US, and



co-author of a related paper published online in the Astronomical Journal.

Immense dark storms on Neptune were first discovered in the late 1980s by NASA's Voyager 2 spacecraft.
