The NGC 7250 galaxy has contained exploding supernovas, but in this photo taken by the Hubble Space Telescope, it’s overshadowed by a bright star located in the Lizard constellation, which is a million times closer to us than far-off NGC 7250, over 45 million light-years away from Earth.

This false-color image shows five impact basins on Mars, including Borealis (top), Hellas (bottom right), and Argyre (bottom left). Scientists at the Southwest Research Institute discovered a 400-million-year gap between the formation of Borealis and the other basins.

This composite image shows four galaxy clusters, as documented by NASA’s Chandra X-ray Observatory. Chandra is observing 13 galaxy clusters to learn more about properties of dark matter.

This image shows dark sand covering layers of sedimentary rock in Ganges Chasma, a canyon on Mars. Unlike on most Eartly beaches and deserts, sand dunes on Mars are iron- and magnesium-rich, darkening their hue.

These unprocessed images show features in Saturn's atmosphere from closer than ever before. The view was captured by NASA's Cassini spacecraft during its first Grand Finale dive past the planet.

In this image of Mars’ surface, gullies, which still form on the planet today, nestle besides million-year-old craters.

On April 21, NASA’s Cassini spacecraft passed by Titan, one of Saturn’s moons, for the last (and 127th) time. This image was taken from 608 miles away; now Cassini will begins its Grand Finale, diving between Saturn and its rings to collect data before entering its atmosphere in September.
