Dawn spacecraft has spotted organic molecules — the carbon-containing building blocks of life as we know it — on Ceres for the first time, a study published today (Feb. 16) in the journal Science reports.
And these organics appear to be native, likely forming on Ceres rather than arriving via asteroid or comet strikes, study team members said. [

"Because Ceres is a dwarf planet that may still preserve internal heat from its formation period and may even contain a subsurface ocean, this opens the possibility that primitive life could have developed on Ceres itself," Michael Küppers, a planetary scientist based at the European Space Astronomy Centre just outside Madrid, said in an accompanying "News and Views" article in the same issue of Science.
