NASA Jupiter Probe Sets Distance Record for Solar-Powered Spacecraft
Artist’s impression of NASA’s Juno spacecraft at Jupiter.Credit: NASA/JPL-Caltech A NASA spacecraft in the home stretch of its five-year journey to Jupiter has just become the farthest-flung solar-powered probe in history. On Wednesday (Jan. 13), NASA’s Juno spacecraft zoomed past the previous record of 492 million miles (792 million kilometers) from the sun, which was […]

A Milky Way twin swept by an ultra-fast X-ray wind
ESA’s XMM-Newton has found a wind of high-speed gas streaming from the centre of a bright spiral galaxy like our own that may be reducing its ability to produce new stars. To source
Bosom Buddies: A Galactic Pair | Space Wallpaper
This pair of spiral galaxies near the The Triangle, a constellation in the northern sky, draw closer and closer to each other. The two galaxies, known as MRK 1034, show no signs of gravitational disturbances yet, but experts surmise they will steadily pull together, melding into a larger galaxy.

Watch the Moon Blot Out Bright Star Aldebaran Tuesday
As the moon orbits Earth, the satellite regularly passes in front of stars, causing events known as lunar occultations. Most of the stars involved are faint and require a telescope to see, but there are a few really bright stars in the moon’s path, including Regulus, Spica, Antares and Aldebaran, whose occultation can be observed […]
Traces of the First Stars in the Universe Possibly Found
A computer simulation shows how the first stars may have exploded, spreading the first traces of heavy elements through the universe.Credit: Britton Smith, John Wise, Brian O’Shea, Michael Norman and Sadegh Khochfar An enormous cloud of dust and gas may bear the fingerprints of the first stars in the universe. The distant cloud contains only […]
Exposed Water Ice on Comet Reveals Clues About Its Evolution
Images of Comet 67P/Churyumov-Gerasimenko captured by the Rosetta spacecraft’s navigation camera, showing two patches of exposed water ice (which are seen close up in images C and D).Credit: Filacchione et al. and Nature A European spacecraft has spotted water ice on the surface of a comet, shedding new light on the formation and evolution of […]

New Seafloor Map Helps Scientists Find New Features
An international scientific team recently published a new map of the ocean floor based on Earth’s gravity field, and it is a particularly useful tool. The maps were created through computer analysis and modeling of new satellite data from ESA’s CryoSat-2 and from the NASA-CNES Jason-1, as well as older data from missions flown in […]

Double Star Detected By New Black Hole Probe | Video
Known simply as ‘Gravity’, this multi-mode interferometer combines light from several telescopes to enable observations simulating a single extremely large telescope. Applied to the European Southern Observatory’s Very Large Telescope array, ‘Gravity’ detected a binary star pair within the Trapezium Cluster during its first observing run. Credit: ESO/M.
