This NASA/ESA Hubble Space Telescope image shows Messier 96, a spiral galaxy just over 35 million light-years away in the constellation of Leo (The Lion). It is of about the same mass and size as the Milky Way. It was first discovered by astronomer Pierre Méchain in 1781, and added to Charles Messier’s famous catalogue of astronomical objects just four days later.
A crew testing how a small group of humans might cope with a trip to Mars has started their 12-month mission. They will have to eat, communicate, and live exactly as they would on Mars - in a tiny dome in Hawaii.
The Japanese Aerospace Exploration Agency’s fifth H-II Transfer Vehicle, or HTV-5 arrived on Aug. 24 with more than 8,000 pounds of equipment, supplies and experiments in its pressurized cargo compartment.
A pockmarked, icy landscape looms beneath NASA's Cassini spacecraft in new images of Saturn's moon Dione taken during the mission's last close approach to the small, icy world. Two of the new images show the surface of Dione at the best resolution ever.
Cassini passed 295 miles (474 kilometers) above Dione's surface at 11:33 a.m. PDT (2:33 p.m. EDT) on Aug. 17.
This low-angle self-portrait of NASA's Curiosity Mars rover shows the vehicle above the "Buckskin" rock target, where the mission collected its seventh drilled sample. The site is in the "Marias Pass" area of lower Mount Sharp.
The scene combines dozens of images taken by Curiosity's Mars Hand Lens Imager (MAHLI) on Aug. 5, 2015, during the 1,065th Martian day, or sol, of the rover's work on Mars.
A new image released by NASA’s Jet Propulsion Laboratory shows an incredible new surface feature discovered on Saturn’s icy moon of Tethys: enormous, red arcs that span most of the moon’s northern hemisphere.
A NASA camera on the Deep Space Climate Observatory (DSCOVR) satellite has captured a series of stunning images of the Moon passing the Earth’s sunlit side. The images were captured last month by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel camera and telescope.
Road trip! This compilation of images from hazard-avoidance cameras on NASA's Mars Exploration Rover Opportunity between January 2004 and April 2015 shows the rover's-eye-view of the Martian marathon covering 26.2 miles(42.2 kilometers) from its landing location.
NASA has selected four astronauts to train and prepare for commercial spaceflights that will return American launches to U.S. soil and further open up low-Earth orbit transportation to the private sector.
"Some 250 miles overhead, astronauts are conducting critical research not possible on Earth, which makes tremendous advances in our lives while helping to expand human presence beyond low Earth orbit," said William Gerstenmaier, NASA associate administrator for Human Exploration and Operations.
