    What if we had a way of attainng part of the speed of light, and then partially attracted the light to us magnetically, or with gases, somehow, or a type of gravity. Doesn't gravity of a celestial body depend upon the chemical make-up of the celestial body, and how is that in congruence with mass, change gravity. Light cannot escape a black hole, but gases can. Maybe on the flip side of some of these black holes, the gases that escape it, converge, and start a new nebulae.

    Astronomers unveiled today what they are calling the best map ever produced of the Milky Way galaxy. The new view shows our spiral galaxy as it would look face-on to a very distant observer. The map is based on findings about the structural evolution of the Milky Way presented this week at the 212th meeting of the American Astronomical Society in St. Louis, Missouri. Robert Benjamin of the University of Wisconsin-Whitewater was among the scientists who presented results at a briefing today with reporters. The researchers determined that the Milky Way actually has two fewer major arms than previously believed....

    ST. LOUIS — As if in a cosmic hug, the spiral arms of some galaxies wrap around themselves more tightly than others. The key to the bear hug: Galaxies holding heftier black holes at their centers also have more tightly wound spiral arms, an astronomer announced today. The finding gives astronomers a way to weigh so-called supermassive black holes, which can have masses of millions to billions that of the sun, and are thought to reside at the centers of galaxies. "This is a really easy way to determine the masses of these super-massive black holes at the centers of...

    Astronomers have glimpsed what may be the farthest galaxy we've ever seen, providing a picture of a baby galaxy born soon after the beginning of the universe. Images taken with the Hubble Space Telescope have revealed the galaxy at almost 13 billion light-years away, making it the strongest candidate for the most distant galaxy ever seen, said European Southern Observatory astronomer Piero Rosati, who helped make the discovery. Since the galaxy is so far away, its light took ages to reach us, so what we see now is a snapshot of how this galaxy looked 13 billion years ago. At...

    A young star speeding away from the Milky Way is in fact an alien visitor, astronomers have confirmed. The wayward object is one of several rogues that are giving astronomers a glimpse into the volatile nature of our galaxy and others. Astronomers have found about 10 stars hurtling away from our galaxy, at speeds that exceed its gravitational grasp. While most stars rush through space at speeds on the order of hundreds of kilometers per second, these aptly-named "hypervelocity stars" are rocketing away at least twice as fast. Most of these speedy stars are thought to be exiles from the...

    A mushroom-shaped hydrogen cloud rearing 1000 light years above the plane of our galaxy is the aftermath of a massive gas cloud that dive-bombed the Milky Way, new computer simulations suggest. The work explains why the cloud is unlike any other found so far. The cloud, called GW 123.4-1.5, was discovered in 1999 by Jayanne English of the University of Manitoba in Winnipeg, Canada, and colleagues, who found it in a radio survey of the galactic plane. Two explanations for its familiar shape were offered at the time – that the mushroom is a bubble of gas blown out by...

    For the first time astronomers have witnessed a supermassive black hole blasting its galactic neighbor with a deadly beam of energy.The "death star galaxy," as NASA astronomers called it, could obliterate the atmospheres of planets but also trigger the birth of stars in its wake of its destructive beam. Fortunately, the cosmic violence is a safe distance from our own neck of the cosmos."We've seen many jets produced by black holes, but this is the first time we've seen one punch into another galaxy like we're seeing here," said Dan Evans, astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge,...

    Black holes are weird. Well, duh, right? But they do something that surprises most people: besides hoovering down almost everything nearby, they can also eject material as well. And by eject, I mean send it out screaming at nearly the speed of light and heated to a bazillion degrees. Picture from Chandra of the active galaxy pair 3C321 The image above is from the Chandra X-Ray Observatory, and it’s all about this scary scenario. Let’s take a walk down the gravity well, shall we?

    An international team of astronomers have conclusive new evidence that a recently discovered "dark galaxy" is, in fact, an object the size of a galaxy, made entirely of dark matter. Although the object, named VIRGOHI21, has been observed since 2000, astronomers have been slowly ruling out every alternative explanation. In a new research paper, entitled 21-cm synthesis observations of VIRGOHI 21 – a possible dark galaxy in the Virgo Cluster, researchers provide updated evidence about this mysterious galaxy. They have now performed a high resolution observations of VIRGOHI21 using the Westerbork Synthesis Radio Telescope (WSRT), to better pin down the...

    The Sombrero Galaxy appears to hover in space like a glowing UFO in a new composite image made from three of NASA's Great Observatories. Data from a trio of space telescopes – Chandra, Spitzer and Hubble – have been combined to produce the new image. Chandra observations reveal hot gas that glows in X rays and extends about 60,000 light years from the centre of the galaxy, which itself is only 50,000 light years wide. The gas is probably being blown outwards by a wind driven by supernova explosions in the galaxy.

    Astronomers have found that a diffuse X-ray glow in our galaxy is not generated by hot gas but rather it's radiating from old stars that have yet to be counted. There could be roughly a billion stars we didn't know about in the Milky Way, they said Wednesday. The discovery, if confirmed, "would have a profound impact on our understanding of the history of our galaxy, from star-formation and supernova rates to stellar evolution," according to a statement released by NASA.

    After creating the most detailed analysis yet of what the Milky Way looks like, astronomers say a long bar of stars cuts on an angle through the center of the galaxy that includes the sun and planet Earth. Some scientists have suspected the presence of the stellar bar, but the survey led by two Wisconsin astronomers shows the bar is far longer than previously believed, and at a specific angle. The skinny bar is made up of old and red stars and is about 27,000 light years in length, about 7,000 light years longer than previously believed. The bar is...

    The Milky Way is not a perfect spiral galaxy but instead sports a long bar through its centre, according to new infrared observations from NASA's Spitzer Space Telescope. Galaxies come in a wide variety of shapes usually thought to be produced by gravitational interactions with nearby objects. Some spiral galaxies look like pinwheels, with their arms curving out from a central bulge, while others have a straight bar at their centres. Radio telescopes detected gas that hinted at a bar at the heart of the Milky Way in the late 1980s. A decade later, observations with the near infrared survey...

    WASHINGTON (Reuters) - The Andromeda galaxy just got bigger -- three times bigger, astronomers said on Monday. The galaxy is not actually expanding. But new measurements suggest that the nearest galaxy to our own Milky Way is three times broader than astronomers had thought. They now believe a thin sprinkling of stars once thought to be a halo is in fact part of Andromeda's main disk. That makes the spiral galaxy, so close to Earth that it appeared as a fuzzy blob to the ancients, more than 220,000 light-years across -- triple the previous estimate of 70,000 to 80,000 light-years....

    An outcast star is zooming out of the Milky Way, the first ever seen escaping the galaxy, astronomers reported on Tuesday. The star is heading for the emptiness of intergalactic space after being ejected from the heart of the Milky Way following a close encounter with a black hole, said Warren Brown, an astronomer at the Harvard-Smithsonian Center for Astrophysics. The outcast is going so fast -- over 1.5 million mph -- that astronomers believe it was lobbed out of the galaxy by the tremendous force of a black hole thought to sit at the Milky Way's center. That speed...

    SAN DIEGO -- Strange objects in faraway space known to astronomers only as Giant Galactic Blobs have, upon close inspection, become a lot weirder. The blobs are huge clouds of glowing gas. They've been puzzling astronomers since their discovery five years ago. Researchers discussed new observations of the object here today at a meeting of the American Astronomical Society. NASA's Spitzer Space Telescope, which works like night-vision goggles to detect infrared radiation, peeked inside the blobs to reveal galaxies lurking within. Turns out there are typically two or more galaxies inside a given blob. Take Blob B6, for example (yes,...

Cuillandre (CFHT), Coelum Explanation: Why isn't spiral galaxy M66 symmetric? Usually density waves of gas, dust, and newly formed stars circle a spiral galaxy's center and create a nearly symmetric galaxy. The differences between M66's spiral arms and the apparent displacement of its nucleus are all likely caused by the tidal gravitational pull of nearby...

    Hubble's deepest view ever unveils earliest galaxiesSPACE TELESCOPE SCIENCE INSTITUTE NEWS RELEASEPosted: March 9, 2004 Astronomers at the Space Telescope Science Institute today unveiled the deepest portrait of the visible universe ever achieved by humankind. Called the Hubble Ultra Deep Field (HUDF), the million-second-long exposure reveals the first galaxies to emerge from the so-called "dark ages," the time shortly after the big bang when the first stars reheated the cold, dark universe. The new image should offer new insights into what types of objects reheated the universe long ago. This view of nearly 10,000 galaxies is the deepest visible-light image...

    French and Swiss astronomers say they have detected the farthest galaxy ever observed, a glimmer that dates back to when the universe was still in its infancy. The galaxy, dubbed Abell 1835 IR1916, is 13.23 billion light-years from Earth — beating by a chunk another galaxy that until now was believed to be the farthest known object, said France's state-funded National Center for Scientific Research, a major European research organizations. Because light from the new find took 13.23 billion years to reach us across the vastness of space, astronomers are seeing the galaxy as it was back then. The universe,...
