    If your rocking a Samsung smartphone, you could be vulnerable to hackers, thanks to a preinstalled keyboard on your device.The vulnerability was discovered by Ryan Welton from mobile security specialists NowSecure. The issue is with the preinstalled Swift keyboard which looks for language pack updates over an unencrypted line. Welton found that a hacker could create a spoof proxy server and send a fake update to the device with malicious code. The hacker could then exploit the device by eavesdropping on incoming and outgoing messages or voice calls, access personal data such as pictures or text messages, tamper with apps,...
  • More evidence that the Milky Way has four spiral arms

    Astronomers have been arguing over just how many spiral arms our galaxy exhibits. Is the Milky Way a four or two-armed spiral galaxy? Astronomers had often assumed the Milky Way was potentially a four-armed spiral galaxy, but comparatively recent observations from NASA's Spitzer telescope implied the galaxy had two spiral arms. In 2013, astronomers mapped star forming regions and argued they had found the two missing arms, bringing the total number of arms back to four. The case for a four-armed Milky Way may have just gotten stronger. A team of Brazilian astronomers used star clusters embedded in their natal...

    An international team of astronomers led by Yale University and the University of California-Santa Cruz have pushed back the cosmic frontier of galaxy exploration to a time when the universe was only 5% of its present age. The team discovered an exceptionally luminous galaxy more than 13 billion years in the past and determined its exact distance from Earth using the powerful MOSFIRE instrument on the W.M. Keck Observatory's 10-meter telescope, in Hawaii. It is the most distant galaxy currently measured. The galaxy, EGS-zs8-1, was originally identified based on its particular colors in images from NASA's Hubble and Spitzer space...

    The Corrugated Galaxy The disk of the Milky Way Galaxy disk may actually be rippled. Two ringlike structures of stars wrapping around the Milky Way's outer disk now appear to belong to the disk itself. The results, outlined in a new study, show that the disk is about 60 percent larger than previously thought. Not only do the results extend the size of the Milky Way, they also reveal a rippling pattern, which raises intriguing questions about what sent wavelike fluctuations rippling through the disk. The researchers said the likely culprit was a dwarf galaxy. It might have plunged...

    Explanation: The view was worth the trip. Battling high winds, cold temperatures, and low oxygen, the trek to near the top of the volcano Santa Maria in Guatemala -- while carrying sensitive camera equipment -- was lonely and difficult. Once set up, though, the camera captured this breathtaking vista during the early morning hours of February 28. Visible on the ground are six volcanoes of the Central America Volcanic Arc, including Fuego, the Volcano of Fire, which is seen erupting in the distance. Visible in the sky, in separate exposures taken a few minutes later, are many stars much further...

    Life on Earth exists becuase of the sun and our distance from it. Without that star and the energy it gives off, we’d be what NASA once described as a “lifeless ball of ice-coated rock.” Luckily, we are far enough from it, and as of right now, it’s not radiating so much light as to make our planet uninhabitable. In some ways, we’re in the sweet spot, and researchers may have discovered many more such connections. Stars in the Milky Way may have 100 billion planets — two, on average, per star — in their habitable zone, the area far...

    The Milky Way galaxy is at least 50 percent larger than is commonly estimated, according to new findings that reveal that the galactic disk is contoured into several concentric ripples. The research, conducted by an international team led by Rensselaer Polytechnic Institute Professor Heidi Jo Newberg, revisits astronomical data from the Sloan Digital Sky Survey which, in 2002, established the presence of a bulging ring of stars beyond the known plane of the Milky Way. "In essence, what we found is that the disk of the Milky Way isn't just a disk of stars in a flat plane—it's corrugated," said...

    A object from the very early universe is bafflingly rich with dust that theory says shouldn't have formed yet. Photograph by NASA, ESA, the Hubble Heritage Team (STScI/AURA), J. Blakeslee (NRC Herzberg Astrophysics Program, Dominion Astrophysical Observatory), and H. Ford (JHU) Astronomers have spotted a surprisingly dusty little galaxy within the cluster Abell 1689, shown here in an image by the Hubble telescope. Peering back in time to find the very earliest objects in the universe, an international team of astronomers has discovered a galaxy that shouldn't be there at all. The problem, the scientists report Monday in Nature, is...

    When we look out at the Universe, our view is pretty consistently dominated by the stars within our own galaxy. Although we know that many interesting things lie beyond — globular clusters, individual galaxies, and rich clusters and superclusters of galaxies — being in the Milky Way makes it very hard to see a great many of them. This is because our own galaxy, from our vantage point within it, dominates a huge fraction of the sky overhead.

    Astronomers using data from NASA’s Hubble Space Telescope and ground observation have found an unlikely object in an improbable place -- a monster black hole lurking inside one of the tiniest galaxies ever known. The black hole is five times the mass of the one at the center of our Milky Way galaxy. It is inside one of the densest galaxies known to date -- the M60-UCD1 dwarf galaxy that crams 140 million stars within a diameter of about 300 light-years, which is only 1/500th of our galaxy’s diameter. If you lived inside this dwarf galaxy, the night sky would...

    Superclusters – regions of space that are densely packed with galaxies – are the biggest structures in the Universe. But scientists have struggled to define exactly where one supercluster ends and another begins. Now, a team based in Hawaii has come up with a new technique that maps the Universe according to the flow of galaxies across space. Redrawing the boundaries of the cosmic map, they redefine our home supercluster and name it Laniakea, which means ‘immeasurable heaven’ in Hawaiian. Video Link

    Explanation: It is one of the more massive galaxies known. A mere 46 million light-years distant, spiral galaxy NGC 2841 can be found in the northern constellation of Ursa Major. This sharp view of the gorgeous island universe shows off a striking yellow nucleus and galactic disk. Dust lanes, small, pink star-forming regions, and young blue star clusters are embedded in the patchy, tightly wound spiral arms. In contrast, many other spirals exhibit grand, sweeping arms with large star-forming regions. NGC 2841 has a diameter of over 150,000 light-years, even larger than our own Milky Way and captured by this...

    NASA ^ | March 14, 2014 | (see photo credit)
    Explanation: NGC 2685 is a confirmed polar ring galaxy - a rare type of galaxy with stars, gas and dust orbiting in rings perpendicular to the plane of a flat galactic disk. The bizarre configuration could be caused by the chance capture of material from another galaxy by a disk galaxy, with the captured debris strung out in a rotating ring. Still, observed properties of NGC 2685 suggest that the rotating ring structure is remarkably old and stable. In this sharp view of the peculiar system also known as Arp 336 or the Helix galaxy, the strange, perpendicular rings are...

    Texas A&M University and the University of Texas at Austin may be former football rivals, but the Lone Star State's two research giants have teamed up to detect the most distant spectroscopically confirmed galaxy ever found—one created within 700 million years after the Big Bang. The research is published in the most recent edition of the journal Nature. "It's exciting to know we're the first people in the world to see this," said Vithal Tilvi, a Texas A&M postdoctoral research associate and co-author of the paper, set to be available online after Oct. 24. "It raises interesting questions about the...

    Explanation: This intriguing trio of galaxies is sometimes called the Draco Group, located in the northern constellation of (you guessed it) Draco. From left to right are edge-on spiral NGC 5981, elliptical galaxy NGC 5982, and face-on spiral NGC 5985 -- all within this single telescopic field of view spanning a little more than half the width of the full moon. While the group is far too small to be a galaxy cluster and has not been catalogued as a compact group, these galaxies all do lie roughly 100 million light-years from planet Earth. On close examination with spectrographs, the...
