Photo of the Day - Saturn Aurora (Hubble)


The dancing light of the auroras on Saturn behaves in ways different from how scientists have thought possible for the last 25 years. New research by a team of astronomers led by John Clarke of Boston University has overturned theories about how Saturn's magnetic field behaves and how its auroras are generated.


In April, the Hubble Space Telescope is celebrating its 20th year in use, and following a 2009 mission in which the space shuttle Atlantis carried two new instruments to the satellite to operate at its most technologically advanced and powerful state.
