One of NASA’s primary objectives, and the one which most excites the general public, is the search for evidence of life elsewhere, whether in our own Solar System or on […]

Cassini Completes Epic Flyby Through Geysers of Enceladus, Sends Back Stunning New Images

This coming Wednesday, Oct. 28, 2015, the Cassini spacecraft will make a historic close flyby (dubbed “E21”) of Saturn’s tiny icy moon Enceladus, not only passing very close to the surface, but also making the […]

A Colorful World: New Images of Pluto Show Blue Skies and Red Water Ice

The blue skies of Pluto, as seen in this image from New Horizons. Pluto is backlit by the Sun, revealing the multilayered hazes in the atmosphere. Soot-like particles in the atmosphere scatter sunlight in a way that the atmosphere appears blue, similar to what happens on Earth. Image Credit: NASA/JHUAPL/SwRI

As new images […]

Curiosity Rover Continues Journey Up Mount Sharp After Science Observations at 'Marias Pass'

Titan is the only moon in the Solar System known to have a dense atmosphere, and while similar to Earth’s atmosphere in some ways, such as being rich in nitrogen, it also […]

Solar System's Largest Moon Ganymede May Have 'Club Sandwich' Oceans
