Six years ago, NASA’s Dawn mission communicated with Earth for the last time, ending its exploration of Ceres and Vesta, the two largest bodies in the asteroid belt. Since then, Ceres —a water-rich dwarf planet showing signs of geological activity— has been at the center of intense debates about its origin and evolution.

Now, a study led by IAA-CSIC, using Dawn data and an innovative methodology, has identified 11 new regions suggesting the existence of an internal reservoir of organic materials in the dwarf planet. The results, published in The Planetary Science Journal, provide critical insights into the potential nature of this celestial body.

In 2017, the Dawn spacecraft detected organic compounds near the Ernutet crater in Ceres’ northern hemisphere, sparking discussion...
