This enhanced color composite image, made with data from NASA’s Dawn spacecraft, shows the area around Ernutet crater, which is about 32 miles (52 km) in diameter and is located in the northern hemisphere. The bright red portions appear redder with respect to the rest of Ceres. In the new study, planetary researchers found that these red areas around Ernutet are associated with evidence of organic material. Images taken using blue (440 nm), green (750 nm) and infrared (960 nm) spectral filters were combined to create the view. Image credit: NASA / JPL-Caltech / UCLA / MPS / DLR / IDA.

This artist’s impression shows AR Scorpii. In this unique double star a rapidly spinning white dwarf star (right) powers electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star (left) and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.

This artist’s rendering illustrates a conceptual design for a potential future mission to land a robotic probe on the surface of Europa. The lander is shown with a sampling arm extended, having previously excavated a small area on the surface. The circular dish on top is a dual-purpose high-gain antenna and camera mast, with stereo imaging cameras mounted on the back of the antenna. Three vertical shapes located around the top center of the lander are attachment points for cables that would lower the rover from a sky crane, which is envisioned as the landing system for this mission concept.
