    NASA ^ | July 12, 2014 | (see photo credit)
    Explanation: A new star, likely the brightest supernova in recorded human history, lit up planet Earth's sky in the year 1006 AD. The expanding debris cloud from the stellar explosion, found in the southerly constellation of Lupus, still puts on a cosmic light show across the electromagnetic spectrum. In fact, this composite view includes X-ray data in blue from the Chandra Observatory, optical data in yellowish hues, and radio image data in red. Now known as the SN 1006 supernova remnant, the debris cloud appears to be about 60 light-years across and is understood to represent the remains of a...

    Actual Headline: Mega Discovery! 715 Alien Planets Confirmed Using A New Trick On Old Kepler Data Planet-watchers, some exciting news: you know how we keep talking about planet candidates, those planets that have yet to be confirmed, when we reveal stories about other worlds? That’s because verifying that the slight dimming of a star’s light is due to a planet takes time – -specifically, to have other telescopes verify it through examining gravitational wobbles on the parent star. Turns out there’s a way to solve the so-called “bottleneck” of planet candidates vs. confirmed planets. NASA has made use of a...

    Explanation: The Lighthouse nebula was formed by the wind of a pulsar, a rapidly rotating, magnetized neutron star, as it speeds through the interstellar medium at over 1,000 kilometers per second. Some 23,000 light-years distant toward the southern constellation Carina, pulsar and wind nebula (cataloged as IGR J1104-6103) are indicated at the lower right in this remarkable image from the Chandra X-ray Observatory. Energetic particles generated by the pulsar are swept back into the wind's comet-like tail trailing up and to the left, along the direction of the pulsar's motion away from its parent supernova remnant. Both runaway pulsar and...

    Religion and astronomy may not overlap often, but a new NASA X-ray image captures a celestial object that resembles the "Hand of God." The cosmic "hand of God" photo was produced when a star exploded and ejected an enormous cloud of material, which NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, glimpsed in high-energy X-rays, shown in blue in the photo. NASA's Chandra X-ray Observatory had imaged the green and red parts previously, using lower-energy X-rays. "NuSTAR's unique viewpoint, in seeing the highest-energy X-rays, is showing us well-studied objects and regions in a whole new light," NuSTAR telescope principal investigator Fiona...

    NASA ^ | December 06, 2013 | (see photo credit)
    Explanation: For an Earth-orbiting gamma-ray telescope, Earth is actually the brightest source of gamma-rays, the most energetic form of light. Gamma-rays from Earth are produced when high energy particles, cosmic rays from space, crash into the atmosphere. While that interaction blocks harmful radiation from reaching the surface, those gamma-rays dominate in this remarkable Earth and sky view from the orbiting Fermi Gamma-ray Space Telescope's Large Area Telescope. The image was constructed using only observations made when the center of our Milky Way galaxy was near the zenith, directly above the Fermi satellite. The zenith is mapped to the center of...

    Explanation: Why are these people shooting a powerful laser into the center of our Galaxy? Fortunately, this is not meant to be the first step in a Galactic war. Rather, astronomers at the Very Large Telescope (VLT) site in Chile are trying to measure the distortions of Earth's ever changing atmosphere. Constant imaging of high-altitude atoms excited by the laser -- which appear like an artificial star -- allow astronomers to instantly measure atmospheric blurring. This information is fed back to a VLT telescope mirror which is then slightly deformed to minimize this blurring. In this case, a VLT was...

    Okay, but what exactly is a gravitational wave and how could they help us crack the conundrum of the black hole code? A gravitational wave is akin to a ripple in space-time. Albert Einstein predicted that massive bodies changing speed or direction generate these gravitational waves. Picture bodies like a pair of black holes orbiting each other. This then creates a gravitational wave that ripples outwards, like a disturbance in a still pool of water after a leaf has dropped onto its surface and ripples are sent across the surface. Like star-crossed lovers, the black holes of two merging galaxies...

    There might not be a man on the moon right now—but there may soon be a gazing eye. A new private venture aims to build a long-range telescope on our planet's little satellite, and it could happen as soon 2016. A partnership between Moon Express, Inc. and the International Lunar Observatory Association is all set to install the telescope on the humble lump of rock. The plan is to position the 2-meter dish antenna, known as the International Lunar Observatory, on the rim of a crater near the moon’s South pole. The first step will be a proof-of-concept mission, which...

    Launched in March 2009, NASA's Kepler space telescope has detected more than 3,000 potential alien planets. But that exoplanet hunt stalled in mid-May of this year, when the second of Kepler's four orientation-maintaining reaction wheels failed, hobbling the spacecraft. Since then, the Kepler team has been working on possible fixes for the reaction wheels and plans to try them out out in the coming weeks, officials said... Kepler spots exoplanets by noting the telltale brightness dips caused when they cross their parent stars' faces from the instrument's perspective. This is precision work, and the observatory needs three functioning gyroscope-like reaction...

    Our solar system is full of moons. Of the 8 major planets, 6 of them have at least one natural satellite in tow, and several of those moons are very interesting places. Icy moons in the outer solar system may even be secretly harboring life. But what about moons elsewhere in the galaxy? The Hunt for Exomoons with Kepler (HEK) is an astronomy project intended to try and find exomoons. And not just any exomoons; the kind of moons that could be a haven for life. While the Kepler telescope has, sadly, been forced into retirement, the data it collected...

    SETIÂ’s Colossus by Paul Gilster on May 31, 2013 For the most part, the focus of SETI since Project Ozma has been directed at intercepting signals deliberately sent our way. It doesnÂ’t have to be so, of course, because extraneous signals from a civilization going about its business would also be profoundly interesting, and even a civilization not much more advanced than ours might be throwing off powerful evidence of its existence through the planetary radars it uses to detect potential impactors in its own system.

    Explanation: Cosmic dust clouds ripple across this infrared portrait of our Milky Way's satellite galaxy, the Large Magellanic Cloud. In fact, the remarkable composite image from the Herschel Space Observatory and the Spitzer Space Telescope show that dust clouds fill this neighboring dwarf galaxy, much like dust along the plane of the Milky Way itself. The dust temperatures tend to trace star forming activity. Spitzer data in blue hues indicate warm dust heated by young stars. Herschel's instruments contributed the image data shown in red and green, revealing dust emission from cooler and intermediate regions where star formation is just...

    Explanation: Sweeping quickly through southern skies on March 5, Comet PanSTARRS (C/2011 L4) follows the Sun toward the western horizon in this twilight scene. In the foreground is Australia's CSIRO Parkes Radio Telescope, a 64 meter wide steerable dish that is no stranger to the space age exploration of comets. In March of 1986 the Parkes dish tracked ESA's Giotto spacecraft as it flew by Comet Halley and received the first ever closeup images of Halley's nucleus. At naked-eye visibility, Comet PanSTARRS made its closest approach to planet Earth on March 5. Its closest approach to the Sun will be...

    LOS ANGELES - The Spitzer telescope's examination of hundreds of stars has found evidence that the times it takes to form an Earth-sized planet may last hundreds instead of tens of millions of years. The telescope revealed dust rings around nearby stars that couldn't have survived long unless violent collisions between gigantic chunks of rock were replenishing them, scientists said during a press conference Monday at NASA's Jet Propulsion Laboratory in Pasadena. Scientists have long believed that planets are formed when the dust in a disc-like formation around a young star begins to clump. Some of the clumps eventually grow...

Cheops -- for CHaracterising ExOPlanets Satellite -- will target nearby, bright stars already known to have planets orbiting around them. Through high-precision monitoring of the star's brightness, scientists will search for the telltale signs of a 'transit' as a planet passes briefly across its face. In turn, this will allow an accurate measurement of the radius of the planet. For those planets with a known mass, the density will be...

    Explanation: One of the last entries in Charles Messier's famous catalog, big, beautiful spiral galaxy M101 is definitely not one of the least. About 170,000 light-years across, this galaxy is enormous, almost twice the size of our own Milky Way Galaxy. M101 was also one of the original spiral nebulae observed with Lord Rosse's large 19th century telescope, the Leviathan of Parsontown. In contrast, this mulitwavelength view of the large island universe is a composite of images recorded by space-based telescopes in the 21st century.

    Over the past decade, scientists have found evidence of hundreds of planets orbiting stars outside our solar system. A group of volunteers has also joined the search, and they have found several additional planets that initially fell through the cracks. Exoplanets can be detected through a variety of ways, and scientists have increasingly looked for small, regularly repeating dips in light from a star-- a sign of planets passing in front of, or transiting, their home star. This same phenomenon happened in our own solar system earlier this month when Earth-based viewers saw Venus transit the sun for the last...

    He was too weak to travel to California last week for the announcement of the mission's first big success -- the discovery of planet Kepler-22b, a rock with similarities to Earth and a sweet-spot distance from its star that creates temperatures and other conditions that could support life. "From what we have measured so far, we say water could exist. We don't say it's there," Koch said, tempering my excitement over when we get to meet our new neighbors... Doctors made the ALS diagnosis in March 2009, the same month a rocket carried the Kepler telescope into space to begin...

    NASA's Spitzer Space Telescope has detected signs of icy bodies raining down in an alien solar system. The downpour resembles our own solar system several billion years ago during a period known as the "Late Heavy Bombardment," which may have brought water and other life-forming ingredients to Earth. During this epoch, comets and other frosty objects that were flung from the outer solar system pummeled the inner planets. The barrage scarred our moon and produced large amounts of dust. Now Spitzer has spotted a band of dust around a nearby bright star in the northern sky called Eta Corvi that...

    NASA has unveiled a flood of photos showing millions galaxies, stars and asteroids photographed by a prolific sky-mapping telescope that ended its mission earlier this year. For the first time, the space agency publicly released more than half of the 2.7 million images taken by its Wide-field Infrared Survey Explorer (WISE) telescope during its mission to map the entire sky. WISE launched in December 2009 and spent 14 months scanning the heavens in infrared light before shutting down this past February. The $320 million space telescope hunted for asteroids and comets, as well as more distant cosmic objects revealed by...

    DARPA-developed Space Surveillance Telescope is supposed to see objects in deep space like no ground-based system before itYou can bet that if there are little red aliens running around on Mars or spaceships patrolling other planet in our solar system for that matter, a recently powered-up telescope built by the researchers at the Defense Advanced Research Projects Agency might just be able to see them. The Air Force, which operates the DARPA-developed Space Surveillance Telescope (SST) says the telescope's design, featuring unique image-capturing technology known as a curved charge coupled device (CCD) system, as well as very wide field-of-view, large-aperture...

    The first spacecraft ever to circle Mercury has beamed home the first-ever photo taken of the small rocky planet from orbit, showing a stark landscape peppered with craters. NASA's Messenger spacecraft snapped the new Mercury photo today (March 29) at 5:20 a.m. EDT (0920 GMT). The photo shows the stark gray landscape of southern Mercury, a view that is dominated by a huge impact crater. "This image is the first ever obtained from a spacecraft in orbit about the solar system's innermost planet," Messenger mission scientists explained in a statement. The new Mercury photo shows a region around the south...

    An international team of astronomers led by Mary Williams from the Astrophysical Institute Potsdam (AIP) has discovered a new stream of stars in our Milky Way: the "Aquarius Stream," named after the constellation of Aquarius. The stream of stars is a remnant of a smaller galaxy in our cosmic neighbourhood, which has been pulled apart by the gravitational pull of the Milky Way about 700 million years ago. The discovery is a result of the measurement of the velocities of 250,000 stars with the RAVE Survey based at the Australian Astronomical Observatory's UK Schmidt Telescope at Siding Spring Observatory, NSW,...

    A FOCAL Mission into the Oort Cloud by Paul Gilster on November 15, 2010 After all this time, IÂ’m still trying to wrap my head around the idea of massive objects in space as lenses, their distortion of spacetime offering the ability to see distant objects at huge magnification. On Friday we saw how the lensing effect caused by galactic clusters can be used to study dark energy. And consider the early results from the Herschel-ATLAS project, conducted by ESAÂ’s Herschel Space Observatory. Herschel is scanning large areas of the sky in far-infrared and sub-millimeter light. Many of its...
