Images of the Milky Way and the Large Magellanic Cloud are overlaid on a map of the surrounding Galactic halo. The smaller structure is a wake created by the Large Magellanic Cloud’s motion through this region. The larger light-blue feature corresponds to a high density of stars observed in the northern hemisphere of our Galaxy.

The asteroid 31 Euphrosyne glides across a field of background stars in this time-lapse view from NASA’s WISE spacecraft. WISE obtained the images used to create this view over a period of about a day around May 17, 2010, during which it observed the asteroid four times. The moving asteroid appears as a string of orange dots because it is much cooler than the distant background stars. Stars have temperatures in the thousands of degrees, but the asteroid is cooler than room temperature. Thus the stars are represented by shorter wavelength blue colors in this view, while the asteroid is shown in longer wavelength reddish colors. Image credit: NASA / JPL-Caltech.
