The Red Planet isn't always—well, red. As seen in this false-color image from the HiRISE camera aboard NASA’s Mars orbiter, sometimes Mars is blue.

A new dwarf planet has been found within our Solar System. The newly discovered object (2014 UZ224) located beyond Pluto's orbit is believed to be large enough to qualify as a dwarf planet.

They might look like trees on Mars, but they're not. Groups of dark brown streaks have been photographed by the Mars Reconnaissance Orbiter on melting pinkish sand dunes covered with light frost. The above image was taken in 2008 April near the North Pole of Mars. At that time, dark sand on the interior of Martian sand dunes became more and more visible as the spring Sun melted the lighter carbon dioxide ice. When occurring near the top of a dune, dark sand may cascade down the dune leaving dark surface streaks.

The Cartwheel Galaxy is a lenticular galaxy and ring galaxy about 500 million light-years away in the constellation Sculptor. It is an estimated 150,000 light-years diameter, and a mass of about 2.9–4.8 × 10⁹ solar masses; it rotates at 217 km/s.

Frozen beneath a cracked and pitted region in Mars’ mid-northern latitudes lies a sheet of ice with about as much thirst-quenching potential as Lake Superior.
