The young Mars would have had enough water to cover its entire surface in a liquid layer about 140 m deep, but it is more likely that the liquid would have pooled to form an ocean occupying almost half of Mars’s northern hemisphere, and in some regions reaching depths greater than 1.6 km.

The atmosphere of the Neptune-mass exoplanet HAT-P-26b is unexpectedly primitive, composed primarily of hydrogen and helium. By combining observations from Hubble and Spitzer space telescopes, Wakeford et al determined that, unlike Neptune and Uranus, the exoplanet has relatively low metallicity.

This view of a Martian rock slab called ‘Old Soaker,’ which has a network of cracks that may have originated in drying mud, comes from the Mast Camera on NASA’s Curiosity Mars rover. The location is within an exposure of Murray formation mudstone on lower Mount Sharp inside Gale Crater. Mud cracks would be evidence of a time more than 3 billion years ago when dry intervals interrupted wetter periods that supported lakes in the area. Several images from Mast Camera’s left-eye camera are combined into this mosaic view. They were taken on Dec. 20, 2016, during the 1,555th sol of Curiosity’s work on Mars. The Old Soaker slab is about 4 feet (1.2 m) long. Image credit: NASA / JPL-Caltech / MSSS.

Valleys younger than better-known ancient valley networks on Mars are evident on the landscape in the northern Arabia Terra region, particularly in the area mapped here with color-coded topographical information overlaid onto a photo mosaic. The area includes a basin informally named ‘Heart Lake’ at upper left. Data from NASA’s Mars Global Surveyor orbiter are coded here as white and purple for lower elevations, yellow for higher elevation. The elevation information is combined with a mosaic of images from NASA’s Mars Odyssey orbiter, covering an area about 120 miles (about 190 km) wide. The mapped area is centered near 35.91 degrees north latitude, 1 degree east longitude on Mars. Image credit: NASA / JPL-Caltech / ASU.
