Earth and Moon – Seen From Mars at Night

NASA JPL February 06, 2014 The rover’s view of its original home planet even includes our moon, just below Earth. The images, taken about 80 minutes after sunset during the rover’s 529th Martian day (Jan. 31, 2014) are available at http://photojournal.jpl.nasa.gov/catalog/PIA17936 for a broad scene of the evening sky, and at http://photojournal.jpl.nasa.gov/catalog/PIA17935 for a zoomed-in view of Earth and the ...

Dramatic New Impact Crater Spotted on Mars

NASA JPL February 05, 2014 Space rocks hitting Mars excavate fresh craters at a pace of more than 200 per year, but few new Mars scars pack as much visual punch as one seen in a NASA image released today. The image from the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter shows a crater about ... Read More »

Latest Kepler Discovery: A Planet That Wobbles

NASA JPL February 05, 2014 Imagine living on a planet with seasons so erratic you would hardly know whether to wear Bermuda shorts or a heavy overcoat. That is the situation on a weird, wobbly world found by NASA’s planet-hunting Kepler space telescope. The planet, designated Kepler-413b, precesses, or wobbles, wildly on its spin axis, much like a child’s top. ... Read More »

Searching Interstellar Dust for Signs of Life

NASA February 04, 2013 While the origin of life remains mysterious, scientists are finding more and more evidence that material created in space and delivered to Earth by comet and meteor impacts could have given a boost to the start of life. Some meteorites supply molecules that can be used as building blocks to make certain kinds of larger molecules ... Read More »

After 10 Years, Opportunity Rover Still Making Discoveries

NASA JPL January 23, 2014 New findings from rock samples collected and examined by NASA’s Mars Exploration Rover Opportunity have confirmed an ancient wet environment that was milder and older than the acidic and oxidizing conditions told by rocks the rover examined previously. In the Jan. 24 edition of the journal Science, Opportunity Deputy Principal Investigator Ray Arvidson, a professor ... Read More »

Water Discovered Around Dwarf Planet Ceres

ESA January 22, 2014 ESA’s Herschel space observatory has discovered water vapour around Ceres, the first unambiguous detection of water vapour around an object in the asteroid belt. With a diameter of 950 km, Ceres is the largest object in the asteroid belt, which lies between the orbits of Mars and Jupiter. But unlike most asteroids, Ceres is almost spherical ... Read More »

Mystery Rock on Mars Continues to Baffle

NASA JPL January 21, 2014 This before-and-after pair of images of the same patch of ground in front of NASA’s Mars Exploration Rover Opportunity 13 days apart documents the arrival of a bright rock onto the scene. The rover had completed a short drive just before taking the second image, and one of its wheels likely knocked the rock — ... Read More »

Space Droids Battle Each Other in Contest

ESA January 21, 2014 A comet heading towards Earth threatens humanity’s existence – that was the virtual scenario of this year’s Zero Robotics tournament. Secondary-school students from across Europe controlled miniature satellites on the International Space Station in a competition to save our planet. The Space Station was turned into a playing field for the finals. The ultimate robot game ... Read More »

Planet Found Around Sun-Like Star in Star Cluster

ESO January 16, 2014 Astronomers have used ESO’s HARPS planet hunter in Chile, along with other telescopes around the world, to discover three planets orbiting stars in the cluster Messier 67. Although more than one thousand planets outside the Solar System are now confirmed, only a handful have been found in star clusters. Remarkably one of these new exoplanets is ... Read More »
