You’d be forgiven for thinking that the only dwarf planet news right now is on Pluto, but Pluto isn’t the only small world with interesting stuff going on.
ANALYSIS: We STILL Don’t Know What Those Bright Blobs on Ceres Are
Closer to the sun, tucked deep inside the asteroid belt between the orbits of Mars and Jupiter, is another dwarf planet called Ceres (you may have heard of it) and something wonderfully interesting has just been spotted by NASA’s Dawn spacecraft, which has been orbiting Ceres since March.
But today, as reported by Nature’s Alexandra Witze, Dawn mission scientists have announced a brand new discovery that could explain what these bright spots are: They seem to be producing haze.
“At noontime, if you look at a glancing angle, you can see what seems to be haze,” said Christopher Russell, a planetary scientist at the University of California, Los Angeles, and Dawn principal investigator. “It comes back in a regular pattern.”
