WorldWide Telescope. 11 Moons You Should Get to Know. You may have heard already that a fifth moon was discovered orbiting Pluto. (If not, Hubble spotted a fifth moon orbiting Pluto .) We know just enough about P5 to know that it's tiny, and it's a moon. Here are some other wild and wonderful worlds that orbit other worlds: 1. Phobos The larger and innermost moon of Mars, Phobos is probably a captured asteroid. Phobos, taken by Mars Reconnaissance Orbiter; Stickney Crater is at lower right. CfA Press Room. Even dying stars could host planets with life - and if such life exists, we might be able to detect it within the next decade.
This encouraging result comes from a new theoretical study of Earth-like planets orbiting white dwarf stars. Private Asteroid-Hunting Space Telescope to Launch in 2017. This story was updated at 2:12 p.m.
EDT. A private space telescope mission that aims to discover 500,000 near-Earth asteroids is technically sound and on track for a 2017 launch, a review panel says. The mission design and implementation plans for the Sentinel Space Telescope — which is being put together by the nonprofit B612 Foundation and its partner Ball Aerospace — are solid, according to the panel, which is called the Sentinel Special Review Team. "This is a major milestone in the development of Sentinel, and has validated the enormous amount of design and planning work that has already been carried out by Ball Aerospace," SSRT chair Tom Gavin, former director for solar system exploration at NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement.
Mars Rover Finds Bed of Ancient Flowing Stream. Scratch water off NASA’s Mars rover Curiosity’s list of things to find in a two-year quest to learn if the planet most like Earth in the solar system could have supported microbial life.
Less than two months after touching down inside a giant impact basin near the planet’s equator, Curiosity has returned clear evidence of flowing water, scientists told reporters during a conference call Thursday. PHOTOS: Curiosity Flips Powerful Camera’s Dust Cap. Saturn and its Largest Moon Reflect Their True Colors. Posing for portraits for NASA's Cassini spacecraft, Saturn and its largest moon, Titan, show spectacular colors in a quartet of images being released today.

Dark Matter, Dark Energy & Cosmic Rays. The vastness of space and the puzzling nature of the cosmic objects that occupy it provides no shortage of material for astronomers to ponder.
To round up some of the most enduring mysteries in the field of astronomy, the journal Science enlisted help from science writers and members of the Board of Reviewing Editors to choose eight puzzling questions being asked by leading astronomers today. As Robert Coontz, deputy news editor at Science, writes in his introduction to the series, the participants decided that, "true mysteries must have staying power," rather than being questions that might be resolved by research in the near future.
In fact, while some of the topics discussed may one day be solved through astronomical observations, others may never be solved, he added. In no particular order, here are eight of the most compelling mysteries of astronomy, as presented by the journal Science: What is dark energy? How hot is dark matter? Distant Galaxies Revealed in New Space Photo. More than 200,000 galaxies take center stage in a staggering photo snapped by a European telescope, an image that scientists say is the deepest view of the sky ever recorded at this size in infrared light.
The European Southern Observatory's VISTA telescope (the Visible and Infrared Survey Telescope for Astronomy) in Chile captured the galactic treasure trove tucked inside what astronomers thought was an unremarkable patch of the sky. NASA Beams Beatles' 'Across the Universe' Into Space. NASA Beams Beatles' 'Across the Universe' Into Space For the first time ever, NASA beamed a song -- The Beatles' "Across the Universe" -- directly into deep space at 7 p.m. EST on Feb. 4. The transmission over NASA's Deep Space Network commemorated the 40th anniversary of the day The Beatles recorded the song, as well as the 50th anniversary of NASA's founding and the group's beginnings.
Two other anniversaries also are being honored: The launch 50 years ago this week of Explorer 1, the first U.S. satellite, and the founding 45 years ago of the Deep Space Network, an international network of antennas that supports missions to explore the universe. The transmission was aimed at the North Star, Polaris, which is located 431 light years away from Earth. New "Super Earth" Found at Right Distance for Life. A new planet—probably a rocky super-Earth—has been found squarely within its star's habitable zone, making it one of the best candidates yet to support life, its discoverers say.
The planet, dubbed GJ 667Cc, orbits a red dwarf star 22 light-years from Earth, in the constellation Scorpio. A binary pair of orange dwarf stars are part of the same system. (Related: "'Tatooine' Planet With Two Suns Could Host Habitable Moon? ") The new planet has a mass 4.5 times that of Earth and orbits its host star every 28 days. Hubble snaps stunning barred spiral galaxy image. 3 February 2012Last updated at 09:35 NGC 1073 lies in the Cetus (a sea monster in Greek mythology) constellation The Hubble space telescope has captured an image of a "barred spiral" galaxy that could help us better understand our own Milky Way.

The sun closed out 2011 with a flurry of activity, and a keen-eyed NASA spacecraft captured the dramatic outburst on video.
NASA's Solar Dynamics Observatory (SDO) watched as our star erupted in dozens of storms during a 36-hour period on Dec. 29 and Dec. 30. The probe's stunning video, taken in extreme ultraviolet light, shows spouts of plasma and intense flashes of radiation blasting from the solar surface. "Magnetic forces were violently pulling against each other, creating the frenetic activity," SDO researchers wrote in an accompanying update.
"By pulling an image every two minutes, the level of detail we can observe is amazing. " The recent outburst didn't produce any truly gargantuan storms. One medium-size flare is visible as a bright white flash about halfway through the new video. CMEs that hit Earth can wreak havoc on our planet, causing temporary disruptions in GPS signals, radio communications and power grids. Astronomy For Beginners. How to use a telescope - how to use a telescope properly. Let's talk about how to use a telescope properly.
This is an important part of owning a telescope that many new telescope users overlook, or just don't think about. It's wonderful that you have taken an interest in Astronomy, and you're no doubt thinking of buying a telescope, or maybe you already have one. You already have an idea how telescopes work, but you have to know how to use a telescope too. Planetary tilt could affect alien life. Artist's rendition of the Milky Way's billions of planets. (credit: M. Kornmesser / ESO) An exciting announcement was made recently that suggests there could be billions of extraterrestrial-inhabited planets in our very own galaxy. According to MSNBC, a statistical analysis based on a survey of millions of stars suggests that there is at least one planet for every star in the sky, and probably more, adding up to approximately 160 billion planets in the Milky Way.
A team of international scientists recently published findings in the journal Nature that conclude “stars are orbited by planets as a rule, rather than the exception,” and many of those are likely to be similar to Earth. The search for habitable planets and extraterrestrial life is gaining momentum, thanks largely to NASA’s planet-hunting space telescope Kepler. Your Shot - Weekly Wrapper. 2012 Skywatching Events Guide & 2012 Venus Transit. This story was updated on Jan. 2.
As the year 2011 comes to a close, some might wonder what is looming sky-wise for 2012? What celestial events might we look forward to seeing? I've selected what I consider to be the top 12 "skylights" for this coming year, and list them here in chronological order. Not all these events will be visible from any one locality … for the eclipses, for instance, you'll probably have to do some traveling … but many can be observed from the comfort of your backyard. Hopefully your local weather will cooperate on most, if not all, of these dates.
