    NASA ^ | April 21, 2014 | (see photo credit)
    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...

    SEOUL, South Korea — Samsung, the world’s largest smartphone maker, is marching toward the next battlefield in its war against Apple. On Wednesday in Berlin, the Korean mega-corporation unveiled the long-anticipated Galaxy Gear, a wearable smartwatch set for release on Sept. 25. Launched a week before Apple reveals its hyped iWatch, Samsung is trying to dispel its image as a “fast follower,” a common label that it imitates other technologies in tried-and-tested markets, rather than innovating on its own. Whether it has effectively achieved that goal is a matter of debate. Most reviewers have doubted that smartwatches will revolutionize electronics...

    Samsung Electronics Co. Ltd. unveiled a smartwatch on Wednesday that works as an accessory to its market-leading Galaxy smartphone, with a small screen offering basic functions like photos, hands-free calls and instant messaging. The world’s top handset maker hopes the Galaxy Gear will boost the appeal of its range of Android-powered smartphones, as it battles to maintain supremacy in the rapidly saturating high-end mobile market against arch rival Apple Inc. Its launch, timed to coincide with the start of the IFA consumer electronics trade show in Berlin, also signals the South Korean giant is more than just a fast follower...

    Information about the Gear has been leaking out for weeks in bits and pieces. The Android-powered watch will have an AMOLED display, slightly curved to better fit your wrist. But nobody seems quite sure about the size and shape. Design patents filed in Korea (originally spotted by the blog SamMobile) show a futuristic look and elongated screen, but they may not reflect the shipping product. Samsung has admitted it has been working on the watch for a long time, so several versions may have been patented, and some may not be quite ready for release; one rumored model with a...

It happened with the quasars (now known to be gigantic burps from black holes swallowing hot gas), the pulsars (fast-spinning neutron stars sending out blips of radio noise hundreds of times every second), and even the Big Bang itself, first seen as a stream of microwaves slamming into Earth from all directions, nearly 14 billion years after the event itself.Now it may be happening again....

    It's too soon to tell, but Samsung might have finally beaten Apple to become the United State's top smartphone maker, at least for now. A new report by the investment research firm Canaccord Genuity shows that Samsung beat Apple in US sales in May. In particular, Canaccord found the Galaxy S 4, Galaxy Note II and Galaxy S III sold more units combined than Apple's iPhone. It's important to be aware of the methodology Canaccord used to develop their findings. The study surveyed only the retail stores of carriers AT&T, Sprint, T-Mobile and Verizon Wireless.

    WASHINGTON – Thirty-five years after its launch, Voyager 1 appears to have travelled beyond the influence of the Sun and exited the heliosphere, according to a new study appearing online today. The heliosphere is a region of space dominated by the Sun and its wind of energetic particles, and which is thought to be enclosed, bubble-like, in the surrounding interstellar medium of gas and dust that pervades the Milky Way galaxy. On August 25, 2012, NASA's Voyager 1 spacecraft measured drastic changes in radiation levels, more than 11 billion miles from the Sun. Anomalous cosmic rays, which are cosmic rays...

    A string of 13 dwarf galaxies are in orbit around the galaxy Andromeda. The galaxies are spread across a flat plane more than one million light years wide and 30,000 light years thick, moving in synchonicity with each other. The phenomenon is unlike behaviour of other observed galaxies and suggests a hole in our knowledge of galaxy formation.

    A new galaxy class has been identified using observations from ESO’s Very Large Telescope (VLT), the Gemini South telescope, and the Canada-France-Hawaii Telescope (CFHT). Nicknamed “green bean galaxies” because of their unusual appearance, these galaxies glow in the intense light emitted from the surroundings of monster black holes and are amongst the rarest objects in the Universe. Many galaxies have a giant black hole at their center that causes the gas around it to glow. However, in the case of green bean galaxies, the entire galaxy is glowing, not just the centre. These new observations reveal the largest and brightest...

    Explanation: Galaxies don't normally look like this. NGC 6745 actually shows the results of two galaxies that have been colliding for only hundreds of millions of years. Just off the above digitally sharpened photograph to the lower right is the smaller galaxy, moving away. The larger galaxy, pictured above, used to be a spiral galaxy but now is damaged and appears peculiar. Gravity has distorted the shapes of the galaxies. Although it is likely that no stars in the two galaxies directly collided, the gas, dust, and ambient magnetic fields do interact directly. In fact, a knot of gas pulled...

    TOKYO — A Japanese court on Friday rejected patent claims made by Apple against Samsung, a victory for the company after its crushing defeat in the United States last week and a reminder of the global scope of the patent war between the two technology giants. While Apple prevailed over Samsung in the United States, winning an award of $1 billion in damages from a federal jury, the two companies remain neck-and-neck in legal disputes in almost a dozen countries. A judge in South Korea, where Samsung is based, for example, handed down a split decision in a patent case...

Impressive? Not really. This is not the end. This verdict doesn't even matter in the long run. This was just another clash.

Samsung attorneys drew a bead on Apple's claims about the uniqueness of its iPhone design Monday, with stronger counterclaims about preceding designs or "prior art," citing three patent applications that preceded the iPhone. Two Japanese patents and one Korean patent show a rectangular phone form with a large glass face and rounded corners. The glass face varies in size from one patent to the other, but all are much larger than older generations of phones. All three resemble the form of the iPhone,...

    Four billion years from now, the Milky Way galaxy as we know it will cease to exist. Our Milky Way is bound for a head-on collision with the similar-sized Andromeda galaxy, researchers announced today (May 31). Over time, the huge galactic smashup will create an entirely new hybrid galaxy, one likely bearing an elliptical shape rather than the Milky Way's trademark spiral-armed disk. "We do know of other galaxies in the local universe around us that are in the process of colliding and merging," Roeland van der Marel, of the Space Telescope Science Institute in Baltimore, told reporters today.

    Galaxy Arp 220, located 250 million light-years from Earth, is home to seven different supernova explosions all going on at the same time. We've never seen so many stars exploding simultaneously in the same galaxy. A team of astronomers at Chalmers and Onsala Space Observatory found that all seven supernovas went off in the last sixty years (allowing for the 250 million years for the light to reach Earth, of course). In cosmic terms, that's pretty much no time at all, as European Southern Observatory astronomer Rodrigo Parra explains: "In Arp 220, we see far more supernovae than in our...

    The most distant objects in the universe are also the oldest -- or at least that is how they appear to us, because their light has had to travel for billions of years to get here. They are also extraordinarily faint since they are so far away, and only in the last decade have astronomers been able to stretch their vision using the newest telescopes and clever techniques. One such innovation occurred with the launch of the NASA Swift satellite in 2004; it searches for bursts of gamma-ray emission, called GRBs.

    In addition, South Korea will create a cloud-based server system for its schools that allows students to download textbooks on their tablets Mobile devices have become a crucial part of everyday life for many people. More recently, tablets have gained popularity as new models, such as Apple's iPad 2 and Samsung's Galaxy Tab, have upped the mobile experience. Furthermore, tablets are not only being used for entertainment purposes. More and more businesses and schools are replacing textbooks and print manuals with tablets. For instance, Alaska Airlines replaced its flight manuals with iPads, and American Airlines is looking to adopt the...

    Roughly one out of every 37 to one out of every 70 sunlike stars in the sky might harbor an alien Earth, a new study reveals. These findings hint that billions of Earthlike planets might exist in our galaxy, researchers added. These new calculations are based in data from the Kepler space telescope, which in February wowed the globe by revealing more than 1,200 possible alien worlds, including 68 potentially Earth-size planets. The spacecraft does so by looking for the dimming that occurs when a world transits or moves in front of a star. Scientists at NASA's Jet Propulsion Laboratory...

    A hundred million years ago, a triple-star system was traveling through the bustling center of our Milky Way galaxy when it made a life-changing misstep. The trio wandered too close to the galaxy's giant black hole, which captured one of the stars and hurled the other two out of the Milky Way. Adding to the stellar game of musical chairs, the two outbound stars merged to form a super-hot, blue star. This story may seem like science fiction, but astronomers using NASA's Hubble Space Telescope say it is the most likely scenario for a so-called hypervelocity star, known as HE...
  • Massive black hole discovered in nearby galaxy (30 million light-years from Earth)

    WASHINGTON (AFP) – US astronomers have discovered a huge black hole, a million times the mass of the sun, in a nearby galaxy -- a finding that could help better understand the origins of the universe. The announcement Monday by the American Astronomical Society said the surprise discovery in a so-called "dwarf" galaxy offers evidence that black holes -- regions of space where not even light can escape -- formed before the buildup of galaxies. "This galaxy gives us important clues about a very early phase of galaxy evolution that has not been observed before," said Amy Reines, a researcher...

    Astronomers have confirmed the first discovery of an alien planet in our Milky Way that came from another galaxy, they announced today (Nov. 18). The Jupiter-like planet orbits a star that was born in another galaxy and later captured by our own Milky Way sometime between 6 billion and 9 billion years ago, researchers said. A side effect of the galactic cannibalism brought a faraway planet within astronomers' reach for the first time ever. [Illustration of the extragalactic planet] "This is very exciting," said study co-author Rainer Klement of the Max-Planck-Institut fur Astronomie (MPIA) in Heidelberg, Germany. "We have no...

    Displayed in all their exquisite detail, six spectacular galaxies are pictured more clearly that they ever have before. All of them are beautiful examples of spiral galaxies and were captured in images from ESO’s Very Large Telescope (VLT) at the Paranal Observatory in Chile. The pictures were taken in infrared light, using the impressive power of the HAWK-I camera, and will help astronomers understand how the remarkable spiral patterns in galaxies form and evolve.-incredible-new-detail.html#ixzz13uAfNijg

    Nasa man expects first prototype of a spaceship that will take us between worlds ‘within a few years’The US space agency Nasa has announced an intriguing new project called the 'Hundred Year Starship' which aims to send humans on a one-way trip to newly discovered planets across the galaxy. "The human space programme is now really aimed at settling other worlds," said Pete Worden, director of Nasa'a Ames research laboratory, at a seminar in San Francisco. "Twenty years ago you had to whisper that in dark bars [or] get fired." The Ames laboratory is responsible for Pioneer 10, the...

    PARIS (AFP) – European astrophysicists said on Wednesday they could settle a mystery about how galaxies crank up in size, developing from proto-structures in the early Universe to the billion-star behemoths of today. Analysis of ancient light, known as redshift, indicates that the first galaxies were formed nearly 13 billion years ago, about a billion years after the "Big Bang" that created the Universe. They then dramatically fattened up to become the giant systems we see today, and the question is why. Until now, many experts believed that galaxies increased in size by colliding with others, in the same way...
  • A Black Hole With the Mass of a Galaxy (as massive as 18 billion Suns)

    Black-hole Located in the Cancer constellation about 3.5 billion light years away, an object dubbed OJ287 is part of a binary black hole system and produces a huge amount of light, fact that is usually associated with the formation of a new galaxy. Quasars mostly consist of a massive black hole, surrounded by a large accretion disk spinning around it, and are powered by the massive amounts of matter falling towards the black hole at its center. Although compacted into objects with a small size, during the feeding process quasars release enough energy to outshine an entire galaxy. OJ 287...

    The most recent supernova in our Galaxy has been discovered by tracking the rapid expansion of its remains. This result, using NASA's Chandra X-ray Observatory and NRAO's Very Large Array (VLA), has implications for understanding how often supernovas explode in the Milky Way galaxy. The supernova explosion occurred about 140 years ago, making it the most recent supernova in the Milky Way as measured in Earth's time frame. Previously, the last known galactic supernova occurred around 1680, based on studying the expansion of its remnant Cassiopeia A. The recent supernova explosion was not seen in optical light about 140 years...
