  • Spying on a Hubble Telescope Look-Alike

    Updated: 2010-05-29 21:43:59
    Amateur astronomer Ralf Vandebergh from the Netherlands is becoming well-known for his ability to capture images of the space shuttle, space station and other satellites in low Earth orbit. Recently, he tried his hand at something a little more distant: The Keyhole 11-4 satellite, which orbits at about 600 km (360 miles) above [...]

    NASA has released, for the first time, video of the final inspection of a space shuttle before launch. The Final Inspection Team, also known as the "Ice Team," performs a walkdown of Kennedy's Launch Pad 39A during space shuttle Atlantis' STS-132 launch countdown on May 14, 2010. The six-member team walks on every level [...]

  • Giant airplane-mounted telescope sees first light!

    Updated: 2010-05-28 22:09:10
    Very cool news: the flying infrared observatory, SOFIA (Stratospheric Observatory for Infrared Astronomy) — which has been in the works for many years — has seen first light. What’s remarkable about this observatory is that it’s mounted in a hole in the side of a 747! Don’t believe me? Check. This. Out: [Click any of the images [...]

  • Amateur Astronomer Images X37-B Space Plane in Orbit

    Even since amateur astronomers picked up on the orbit of the Air Force's secret X37-B space plane, others have been trying to capture images of the mini-space shuttle look-alike. So far, images have been just streaks or dots, but Universe Today reader Brent (a.k.a. HelloBozos) was actually able to image the plane in some [...]

    Updated: 2010-05-28 00:00:00
    The Herschel Space Observatory has been able to see thousands of galaxies and identify their locations, showing for the first time that they are packed closely together in the center of large galaxy clusters.

  • NASA spacecraft penetrates mysteries of martian ice cap

    Updated: 2010-05-28 00:00:00
    Layers of ice record a history of accumulation, erosion, and wind transport. From that, scientists can determine a history of climate that's more detailed than anybody expected.

  • Andromeda's Unstable Black Hole

    Updated: 2010-05-27 16:23:15
    The Andromeda galaxy, the closest spiral galaxy to our own Milky Way, has a supermassive black hole at the center of it much like other galaxies. Because of its proximity to us, Andromeda – or M31 – is an excellent place to study just how the supermassive black holes in the centers of galaxies consume [...]

  • Black Hole in M87 Wanders using Jetpack

    Updated: 2010-05-27 14:58:09
    The elliptical galaxy M87 is known for a jet of radiation that is streaming from the supermassive black hole (SMBH) that the galaxy houses. This jet, which is visible through large-aperture telescopes, may have functioned as a black hole 'jetpack', moving the SMBH from the center of mass of the galaxy – where most SMBHs [...]

  • NASA's Swift survey finds "smoking gun" of black hole activation

    Updated: 2010-05-27 00:00:00
    Galaxy mergers appear to feed black holes, causing them to give off as much as 10 billion times the Sun's energy.

    Wow. Just wow. Each of the colored dots in this new image from the Herschel telescope is a galaxy containing billions of stars. These are distant luminous infrared galaxies, and appear as they did 10–12 billion years ago, packed together like grains of sand on a beach, forming large clusters of galaxies [...]

    My dotAstronomy pal Edward Gomez from the Las Cumbres Observatory is reporting that a man-made object has been spotted orbiting the sun. First noticed in the Catalina Sky Survey on May 16, it was thought to be an asteroid, but then, because of its very circular and low-inclined orbit, Richard Miles, using the [...]

  • Newly-Discovered Stellar Nurseries in the Milky Way

    Updated: 2010-05-26 20:57:00
    Our Milky Way churns out about seven new stars per year on average. More massive stars are formed in what's called H II regions, so-named because the gas present in these stellar nurseries is ionized by the radiation of the young, massive stars forming there. Recently-discovered regions in the Milky Way that are nurseries for [...]

  • Galaxy Mergers Make Black Holes 'Light Up'

    Updated: 2010-05-26 20:55:37
    Only about 1% of supermassive black holes emit large amounts of energy, and astronomers have wondered for decades why so few exhibit this behavior. Data from Swift satellite, which normally studies gamma ray bursts, has allowed scientists to confirm that black holes "light up" when galaxies collide, and the data may offer insight into [...]

  • New star-forming regions in Milky Way discovered

    Updated: 2010-05-26 00:00:00
    Scientists found concentrations of these regions at the end of the galaxy's central bar and in its spiral arms.

  • Astronomers discover clue to origin of Milky Way gas clouds

    Updated: 2010-05-26 00:00:00
    Astronomers conclude that these clouds have been blown away from the galaxy's plane by supernova explosions and the fierce winds from young stars in areas of intense star formation.

  • Supermassive black holes may frequently roam galaxy centers

    Updated: 2010-05-25 00:00:00
    The most likely cause for M87's supermassive black hole to be off center is a previous merger between two older, less massive ones.

  • Nearby black hole is feeble and unpredictable

    Updated: 2010-05-25 00:00:00
    Andromeda's black hole is fainter in X-ray light than astronomers might expect given the reservoir of gas around it.

  • STEREO, SOHO spacecraft catch comet diving into the Sun

    Updated: 2010-05-25 00:00:00
    Sun-grazing comets, composed of dust, rock and ice, are seldom tracked close to the Sun because their brightness is overwhelmed by the solar disk.

  • Weird orbits of neighbors can make 'habitable' planets not so habitable

    Updated: 2010-05-24 00:00:00
    A Jupiter-like planet's eccentric orbit could effect the orbit of an earthlike planet, possibly causing the smaller planet to cycle between habitable and uninhabitable conditions.
