Red spot on Jupiter becomes smaller
May 18 , 2014
The giant red spot that we see in Jupiter's photos was quite massive in the 1800s but is now getting smaller. Reuters notes that the reason for this is not yet known and the oval spot is becoming more and more circular in shape.
Scientists noticed this change in the 1930s but recently discovered that the shrinkage is becoming faster with time.
There have been several theories: "Some unknown activity in the planet's atmosphere may be draining energy and weakening the storm, causing it to shrink," HubbleSite said.
