Meteorites Reveal Another Way to Make Life's Components | OnOrbit
Creating some of life's building blocks in space may be a bit like making a sandwich - you can make them cold or hot, according to new NASA research. This evidence that there is more than one way to make crucial components of life increases the likelihood that life emerged elsewhere in the Universe,...

NASA's Hubble Space Telescope has produced this beautiful image of the galaxy NGC 1483. NGC 1483 is a barred spiral galaxy located in the southern constellation of Dorado -- the dolphinfish (or Mahi-mahi fish) in Spanish. The nebulous galaxy features a bright central bulge and diffuse arms with dist...
Hubble Reveals New Type of Planet | OnOrbit
Our solar system contains three types of planets: rocky, terrestrial worlds (Mercury, Venus, Earth, and Mars), gas giants (Jupiter and Saturn), and ice giants (Uranus and Neptune). Planets orbiting distant stars come in an even wider variety, including lava worlds and "hot Jupiters."

Images: Steam and Ash Plume over Tinakula Island As Seen From Space | OnOrbit
Tinakula is a small, volcanic island in the South Pacific, located about 2,300 kilometers (1,400 miles) northeast of Brisbane, Australia. This natural-color satellite image (top) shows a plume of volcanic gas, possibly mixed with a bit of ash, rising above the island's summit.
Video: Draper's GENIE Free-Flight Test on Masten Space Systems' Xombie | OnOrbit
Using the GENIE (Guidance Embedded Navigator Integration Environment) System, Draper Laboratory raised Masten Space Systems' Xombie suborbital rocket 50 meters to a stable hover, sent it laterally down range 50 meters, and then had it land safely during a controlled 50 meter descent. The testing, wh...
Oldest Recorded Supernova | OnOrbit
This image combines data from four space telescopes to create a multi-wavelength view of all that remains of RCW 86, the oldest documented example of a supernova. Chinese astronomers witnessed the event in 185 A.D., documenting a mysterious "guest star" that remained in the sky for eight months. X-r...
Image: Snow-bound Italy As Seen From Space | OnOrbit
ESA's Envisat satellite has captured some unusual views of Italy after much the country suffered heavy snowfall a for second time in a week.
Cassini Image: Rhea and Titan | OnOrbit
Craters appear well defined on icy Rhea in front of the hazy orb of the much larger moon Titan in this Cassini spacecraft view of these two Saturn moons. Lit terrain seen here is on the leading hemispheres of Rhea and Titan. North on the moons is up and rotated 13 degrees to the left. The limb, or e...
Cool infographic. I wonder about the proportions on the HLV vs Saturn V
Infrared Sounder on NASA's Suomi NPP Starts its Mission | OnOrbit
Data is flowing in from the Cross-track Infrared Sounder (CrIS) instrument aboard NASA's newest Earth-observing satellite, the Suomi National Polar-orbiting Partnership (NPP). This image is a composite of three days of CrIS data from January 21, 23 and 25, 2012. The orange colors represent very warm...
Subaru Telescope Captures Images of 'Stealth Merger' of Dwarf Galaxies | OnOrbit
An international team of scientists led by David Martinez-Delgado (Max Planck Institute for Astronomy, Germany) has conducted research that reveals a "stealth merger" of dwarf galaxies, where an in-falling satellite galaxy is nearly undetectable by conventional means yet has a substantial influence ...
Chandra Finds Milky Way's Black Hole Grazing on Asteroids | OnOrbit
The giant black hole at the center of the Milky Way may be vaporizing and devouring asteroids, which could explain the frequent flares observed, according to astronomers using data from NASA's Chandra X-ray Observatory.
Mars-Bound Rover Carries Coin for Camera Checkup | OnOrbit
The camera at the end of the robotic arm on NASA's Mars rover Curiosity has its own calibration target, a smartphone-size plaque that looks like an eye chart supplemented with color chips and an attached penny.
