This artist rendering uses an arrow to show the predicted path of the asteroid on Jan. 30, 2008, and the orange swath indicates the area it is expected to pass through. Mars may or may not be in its path. Image credit: NASA/JPL

NASA's Hubble Space Telescope took this close-up of the red planet Mars when it was just 55 million miles -- 88 million kilometers -- away. This color image was assembled from a series of exposures taken within 36 hours of the Mars closest approach with Hubble's Wide Field and Planetary Camera 2. Mars will be closest to Earth on December 18, at 11:45 p.m. Universal Time (6:45 p.m. EST).

This images compares the composite image of 3C321 to an artist's illustration of the system, showing the main galaxy and the companion galaxy.

In this image the fans are dark, but small narrow bright streaks can be detected. Image Credit: NASA/JPL/University of Arizona.
