In this video, Karl Battams of the Naval Research Lab talks us through a visualization of the comets that SOHO has witnessed. Since its launch nearly 20 years ago, NASA and the European Space Agency's Solar and Heliospheric Observatory has spotted 3000 comets.
This new view of Pluto’s crescent -- taken by New Horizons’ wide-angle Ralph/Multispectral Visual Imaging Camera (MVIC) on July 14 and downlinked to Earth on Sept. 13 -- offers an oblique look across Plutonian landscapes with dramatic backlighting from the sun. It spectacularly highlights Pluto’s varied terrains and extended atmosphere. The scene measures 780 miles (1,250 kilometers) across.
Sept. 15, 2015 marked the halfway point in the yearlong mission on the International Space Station with NASA astronaut Scott Kelly and Russian cosmonaut Mikhail Kornienko. Also, I spy the space station: Live!, Expedition 43 post-flight visit, Key milestone for Orion spacecraft, Global ocean on Enceladus, Connecting space to village and more!
Spacesuit engineers demonstrate how four crew members would be arranged for launch inside the Orion spacecraft, using a mockup of the vehicle at Johnson Space Center.
This image, made using images taken by NASA's Dawn spacecraft, shows Occator crater on Ceres, home to a collection of intriguing bright spots. The bright spots are much brighter than the rest of Ceres' surface, and tend to appear overexposed in most images.
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.
