Dwarf planet/asteroid Ceres is shining two bright lights at a NASA spacecraft & our scientists are unsure what they are.
Ceres, is the largest object in the asteroid belt between Mars and Jupiter, officially designated as a dwarf planet.
NASA's Dawn spacecraft is approaching Ceres ahead of a March 6 rendezvous. The picture was taken February 19, from a distance of just under 29,000 miles, & shows two very bright areas on the same basin on Ceres' surface.
Previous Dawn images from further away showed a single light on Ceres, which was just as mysterious. Then, the one light turned out to be two as the spacecraft got closer.
"This is truly unexpected and still a mystery to us," said Andreas Nathues, lead investigator for the framing camera team at the Max Planck Institute for Solar System Research in Gottingen, Germany, in a NASA statement. "The brightest spot [of the two] continues to be too small to resolve with our camera, but despite its size it is brighter than anything else on Ceres."
We'll find out more as Dawn approaches Ceres next week and more imagery comes in during the next 16 months, according to NASA.
