2015년 1월 13일, 던 우주선에 의해서 촬영된 이 사진은 가시광선 및 적외선 매핑 분광기를 이용하여 38만 3천 킬로미터 거리에서 촬영한 왜소행성 세레스의 모습이다.

우측의 적외선 사진에서는 세레스의 온도 분포를 알 수 있는데, 온도가 높은 곳이 하얀색, 온도가 낮은 곳은 붉은 색으로 표현되어 있다.

PIA19169: Ceres From Dawn, Visible and Infrared Light

Original Caption Released with Image:

In this image, taken January 13, 2015, the Dawn spacecraft's visible and infrared mapping spectrometer (VIR) captures the dwarf planet Ceres from a distance of 238,000 miles (383,000 kilometers) in both visible and infrared light. The infrared image, right, serves as a temperature map of Ceres, where white is warmer and red is colder.

JPL manages the Dawn mission for NASA's Science Mission Directorate in Washington. Dawn is a project of the directorate's Discovery Program, managed by NASA's Marshall Space Flight Center in Huntsville, Alabama. The University of California at Los Angeles (UCLA) is responsible for overall Dawn mission science. Orbital Sciences Corp. in Dulles, Virginia, designed and built the spacecraft. The German Aerospace Center, the Max Planck Institute for Solar System Research, the Italian Space Agency and the Italian National Astrophysical Institute are international partners on the mission team.
