Two comets display different shapes of X-ray emission, which indicates differences in the solar wind at the time of the observation and the atmospheres of each one. Take a look: http://go.nasa.gov/1SOVKeB

Our Asteroid Grand Challenge ran a challenge to develop a short video describing the work being done to detect, track, characterize, and mitigate potentially hazardous asteroids. Watch "Find Them Now," which uses a narrative based on a fictional asteroid named “Arthur” to explain how the asteroid's spin, size, composition and mass would be determined using radar, astrometry, ground and space-based infrared spectroscopy, and light curve analysis.

Y marks the spot on Saturn's moon Enceladus! This feature, which snakes northward from south pole like a giant tentacle, is actually tectonic in nature, created by stresses in Enceladus' icy shell. More:http://go.nasa.gov/1NxhoTf
