Like a cosmic bull's-eye, Saturn's moons Enceladus and Tethys line up almost perfectly for the Cassini spacecraft cameras. Since the two moons are not only aligned, but also at relatively similar distances from Cassini, the apparent sizes in this image are a good approximation of the relative sizes of Enceladus (313 miles or 504 kilometers across) and Tethys (660 miles or 1,062 kilometers across). This view looks toward the unilluminated side of the rings from 0.34 degrees below the ring plane. The image was taken in red light with the Cassini spacecraft narrow-angle camera on Sept. 24, 2015.

The Soyuz spacecraft launched from the Baikonur Cosmodrome in Kazakhstan to the International Space Station (@ISS) at 6:03 a.m. EST Tuesday (5:03 p.m. in Baikonur). Tim Kopra of NASA, Tim Peake of ESA (European Space Agency), and Yuri Malenchenko of Roscosmos are now safely in orbit. Malenchenko, Kopra, and Peake will spend the next six-months living and working aboard the International Space Station.

The spiral galaxy NGC 7252 has a superficial resemblance to an atomic nucleus surrounded by the loops of electronic orbits, and was informally dubbed the "Atoms for Peace" galaxy. These loops are well visible in a wider field of view image. This nickname is quite ironic, as the galaxy’s past was anything but peaceful. Its peculiar appearance is the result of a collision between two galaxies that took place about a billion years ago, which ripped both galaxies apart. The loop-like outer structures, likely made up of dust and stars flung outwards by the crash, but recalling orbiting electrons in an atom, are partly responsible for the galaxy’s nickname.

NASA Armstrong's F-15D Eagle #897 flies as a chase vehicle for NASA's DC-8 flying laboratory on the Olympic Mountain Experiment (OLYMPEX) science mission. The OLYMPEX team of NASA and university scientists are taking to the field from Nov. 10 to Dec. 21, studying wet winter weather near Seattle, Washington to verify rain and snowfall observations made by the Global Precipitation Measurement (GPM) satellite mission. NASA currently flies an F-15D Eagle aircraft for research support and pilot proficiency. Research support aircraft are commonly called chase planes and fill the role of escort aircraft during research missions. Chase pilots are in constant radio contact with research pilots and serve as an "extra set of eyes" to help maintain total flight safety during specific tests and maneuvers. They monitor certain events for the research pilot and are an important safety feature on all research missions. Chase aircraft also are used as camera platforms for research missions that must be photographed or videotaped. Aeronautical engineers use these photos and video extensively to monitor and verify various aspects of research projects. The F-15D is also used by research pilots for routine flight training required by all NASA pilots.

Commander Scott Kelly (@StationCDRKelly) of NASA captured this image from aboard the International Space Station (@ISS), of the Dec. 11, 2015 undocking and departure of the Soyuz carrying home crew members Kjell Lindgren of NASA (@Astro_Kjell), Oleg Kononenko of the Russian Federal Space Agency and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) after their 141-day mission on the orbital laboratory. They landed safely in Kazakhstan at approximately 8:12 a.m. EST (7:12 p.m. Kazakhstan time). While on station, the crew members participated in Earth observations and conducted research in the areas of physical, biological and molecular science to advance knowledge and demonstrate new technologies. Such investigations enable research breakthroughs and drive technology innovations that provide benefits on Earth, and will enable long-duration human and robotic exploration missions into deep space.

Three International Space Station (@ISS) crew members are returning to Earth today after 141 days in space. Flight Engineers Kjell Lindgren of NASA; Oleg Kononenko of Roscosmos, the Russian Federal Space Agency; and Kimiya Yui of the Japan Aerospace Exploration Agency (JAXA) will land in their Soyuz spacecraft at 8:12 a.m. EST in Kazakhstan. Prior to undocking from the station at 4:49 a.m. EST, Astronaut Kjell Lindgren shared this image of a trio of crewmates inside their Soyuz saying "All loaded up! Farewell to our Exp 45 crewmates and the magnificent International Space Station! Hello Earth!!" Image credit: NASA #nasa #space #spacestation #soyuz #astronaut #astronauts; -
This enhanced color mosaic combines some of the sharpest views of Pluto that NASA’s New Horizons spacecraft obtained during its July 14 flyby. The pictures are part of a sequence taken near New Horizons’ closest approach to Pluto, with resolutions of about 250-280 feet (77-85 meters) per pixel – revealing features smaller than half a city block on Pluto’s surface. Lower resolution color data (at about 2,066 feet, or 630 meters, per pixel) were added to create this new image. The images form a strip 50 miles (80 kilometers) wide, trending (top to bottom) from the edge of “badlands” northwest of the informally named Sputnik Planum, across the al-Idrisi mountains, onto the shoreline of Pluto’s “heart” feature, and just into its icy plains. The wide variety of cratered, mountainous and glacial terrains seen here gives scientists and the public alike a breathtaking, super-high-resolution color window into Pluto’s geology.

Dwarf planet Ceres is shown in these images from NASA’s Dawn spacecraft that create a movie of Ceres rotating. Ceres reveals some of its well-kept secrets in two new studies in the journal Nature, thanks to data from Dawn. They include highly anticipated insights about mysterious bright features found all over the dwarf planet's surface. In one study, scientists identify this bright material as a kind of salt. The second study suggests the detection of ammonia-rich clays, raising questions about how Ceres formed. These images are false-color renderings, which highlight differences in surface materials.

Tethys, dwarfed by the scale of Saturn and its rings, appears as an elegant crescent in this image taken by NASA's Cassini Spacecraft. Views like this are impossible from Earth, where we only see Saturn's moons as (more or less) fully illuminated disks. The image was taken in visible light with the Cassini spacecraft wide-angle camera on Aug. 18, 2015. The view was acquired at a distance of approximately 184,000 miles (296,000 km) from Tethys.

A United Launch Alliance Atlas V rocket lifts off from Space Launch Complex 41 at Cape Canaveral Air Force Station for the Orbital ATK CRS-4 commercial resupply services mission to the International Space Station (@ISS). Liftoff was at 4:44 p.m. EST. The Cygnus resupply spacecraft will deliver more than 7,000 pounds of essential crew supplies, equipment and scientific experiments to the station.

This composite image shows an infrared view of Saturn's moon Titan from NASA's Cassini spacecraft, acquired during the mission's ''T-114'' flyby on Nov. 13, 2015. A view at visible wavelengths would show only Titan's hazy atmosphere. The near-infrared wavelengths in this image allow Cassini's vision to penetrate the haze and reveal the moon's surface. During this Titan flyby, the spacecraft's closest-approach altitude was 6,200 miles (10,000 km), which is considerably higher than those of typical flybys, which are around 750 miles (1,200 km). The high flyby allowed VIMS to gather moderate-resolution views over wide areas (typically at a few km per pixel).

Launch scrub: Because of wind gusts that exceeded the weather criteria for launching, Orbital ATK and United Launch Alliance have postponed the planned launch of the Atlas V rocket carrying the Cygnus spacecraft. It is Orbital ATK’s fourth commercial resupply services mission to the International Space Station. Launch managers have set Saturday, Dec. 5 at 5:10 p.m. EST for the next launch attempt.

Astronomers have found the faintest object ever seen in the early universe. It existed about 400 million years after the big bang, 13.8 billion years ago. This is a Hubble Space Telescope view of a very massive cluster of galaxies, MACS J0416.1-2403, located roughly 4 billion light-years away and weighing as much as a million billion suns. The inset is an image of an extremely faint and distant galaxy that existed only 400 million years after the big bang. Hubble captured it because the gravitational lens makes the galaxy appear 20 times brighter than normal. Credits: NASA, ESA, and L.
