    Inside a very big and very clean room at NASA’s Goddard Space Flight Center in Greenbelt, Md., nearly 30 workers dressed in white protective suits, goggles and blue booties cluster around the parts of a time machine. These parts — gold-covered mirrors, tennis-court-size sun shields, delicate infrared cameras — are slowly being put together to become the James Webb Space Telescope.

    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...

  • Gravitational Wavelengths Could Crack the Black Hole Code

    guardianlv.com ^ | October 20, 2013. | Jessica Rosslee on
    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...

    Molten sphere could give clues to planetary mass Researchers at the Massachusetts Institute of Technology have discovered a new, Earth-sized exoplanet for which orbiting its star is literally all in a day's work.The newly discovered planet, dubbed Kepler 78b, completes one full revolution around its star in just 8.5 hours – fast enough that by the time you clock in at the office and clock out again, another solar year will have passed for Kepler 78b. To achieve this rapid orbital period, the planet revolves around its star at a distance 40 times closer than Mercury is to our sun.As...

    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. Whether or not the Ohio State WOW! signal was a SETI detection remains unresolved,...

    Kulesa and his team communicate with the telescope remotely via satellite, sending it new orders and instructions throughout the year, and downloading new data. They also keep a watchful eye on their experiment through a webcam, which sends image updates from roughly 9,000 miles away roughly every hour. Why Antarctica, though? Even the smallest amount of water vapor in Earth's atmosphere absorbs terahertz-frequency light from space before it reaches a telescope on Earth... From Tucson, Kulesa said, it's about 5-10 millimeters deep in winter and up to 40 millimeters deep during monsoon season in summer. At the telescope site in...

    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: In silhouette against the colorful evening twilight, clouds part for this much anticipated magic moment. The scene captures naked-eye Comet PanSTARRS peeking into northern hemisphere skies on March 12. The comet stands over the western horizon after sunset, joined by the thin, flattened crescent of a day old Moon. Posing for its own beauty shot, the subtly lit dome of the 4.2 meter William Herschel Telescope is perched above cloud banks on the Canary Island of La Palma. While PanSTARRS has not quite developed into the spectacular comet once hoped for, it is still growing easier to see in...
