Gas Blob

1 April 2020

Sent in by Robert a few days ago. Data from NASAs Voyager 2 flyby of Uranus 30 years ago has been reconsidered and they have found the signature of a massive bubble that may have stolen a blob of the planet's gassy atmosphere. Scientists think it is a plasmoid, a structure that was not properly understand in 1986. Now, plasmoids are reasonably well researched and what they have is a bubble of plasma – a soup of charged particles. The spacecraft actually ploughed its way through the plasmoid – which was as extensive as 250,000 miles across. A big bubble then, from a big planet.
