Thanks to previous results from Dawn's visible and infrared mapping spectrometer, NASA already knows that the bright spots on Ceres' surface are made of sodium carbonate. The photos, however, will help the scientists figure out the origin of its brightest one, which is right in the center of the crater. They could also determine if the carbonates found on Ceres came from a shallow, sub-surface reservoir of water rich in minerals or from a deeper source of water that moved upwards and seeped through cracks.

In addition, the photos might also shed light on the materials found on the dwarf planet's surface, giving us more information about its composition. You can see all the photos the Dawn spacecraft already sent back on its official website, but make sure to check back every once in a while to see what else it beams back to its ground team. This orbit is the beginning of the end for Dawn, which was launched in 2007 and arrived at Ceres in 2015. It's bound to run out of fuel later this year and will remain in orbit around the dwarf planet for at least 50 years.

Dawn's principal investigator Carol Raymond said in a statement:

"The first views of Ceres obtained by Dawn beckoned us with a single, blinding bright spot. Unraveling the nature and history of this fascinating dwarf planet during the course of Dawn's extended stay at Ceres has been thrilling, and it is especially fitting that Dawn's last act will provide rich new data sets to test those theories."
