ALT This composite image of colorful, overlapping clouds, suggests to astronomers that a supernova remnant may be buried in gas near the center of our Milky Way galaxy. Set against a backdrop packed with distant stars and other specks of light are two distinct, overlapping clouds. The larger, visually dominant cloud, is red and multifaceted. It has an irregular shape, and features patches of different textures, including pockets that resemble wispy smoke, tangles of faint red veins, and clear streaking lines. This large cloud of expanding gas represents radio data from the MeerKAT telescope in South Africa. Overlapping with that red cloud is a cloudy blue blob representing X-ray data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton. Astronomers suggest that this blue blob of X-ray emissions is the remains of a massive star destroyed by a supernova.

ALT NASA's Mars Exploration Rover Spirit welcomed the beginning of 2006 on Earth by taking a striking panorama of intricately rippled sand deposits in Gusev Crater on Mars. This is an approximate true-color rendering of the "El Dorado" ripple field provided by Spirit. Spirit used the Pancam's 750-nanometer, 530-nanometer and 430-nanometer filters to capture the colors on Mars. Scientists eliminated seams between individual frames in the peachy sky portion of the mosaic to better simulate the vista a person standing on Mars would see. Hills are visible in the far distance.
