A camera on the Mars Reconnaissance Orbiter snapped this mosaic of images of the 55-kilometer-wide Mojave Crater. The impact that created the crater may have ejected many of the Martian meteorites now found on Earth.

STAR RIVERS The galaxy ESO 137-001, 200 million light-years away, leaves trails (shown in blue in this false-color Hubble Space Telescope image) of gas and newly born stars as it plows through the Norma Cluster. Bright stars in the foreground sit within our galaxy.
