  • Astronomers Prepare to Search for Alien Life at Nearby 'Habitable' Exoplanet

    Seeker ^ | 20 Jan, 2017
    The Wolf 1061 star system is only 14 light-years away and a team of astronomers are doing the groundwork to begin looking for signs of extraterrestrial biology in one of its planet's atmospheres. As we continue the hunt for habitable worlds beyond our solar system, we're finding more and more candidates closer to home. There's even a small rocky exoplanet within the so-called "habitable zone" at Proxima Centauri, the dinky red dwarf star right next door. But there's more, and astronomers are beginning to identify which of these strange new worlds we could soon get a good look at with...

    We know one lurks at the center of the Milky Way, but to these astronomers, seeing will be believing. The center of the galaxy doesn’t look like much, even if you’re lucky enough to live in a place where the night sky is sufficiently dark to see the bands of the Milky Way. In visible light, the stars between here and there blur together into a single brilliant source, like a bright beam hiding the lighthouse behind it. But in other types of radiation—radio waves, infrared, X-rays—astronomers have detected the presence of an object with the mass of four million...

    This new picture from NASA's Cassini probe shows off the peculiarity of Daphnis, a moon so tiny it wasn't discovered until 2005. It's just 8 kilometres (5 miles) across, and irregularly shaped, which gives it a wobbly orbit. ... The Keeler gap is just 42 kilometres (26 miles) wide, and Daphnis' distance varies from Saturn by about 9 kilometres (5.6 miles), while it moves up and down by about 17 kilometres (10.5 miles). This eccentricity, and Daphnis' gravity, causes peaked waves to form on the edges of the gap, in both vertical and horizontal directions. In this new image, taken...

    When you think about our Solar System, with its lone, luminous star dominating both the mass and light of our local corner of the Milky Way, you might think that this is what 'typical' looks like. In some ways, this is true, but a Solar System with multiple stars -- binaries, trinaries or more -- might be even more common. At interstellar distances, many of these binaries are too close together to resolve even with the most powerful of telescopes. Instead, it's only the variations in their light, where the stars more relative to one another, periodically eclipse (passing in...

    It’s the big astrophysical whodunnit. Across the Universe, galaxies are being killed and the question scientists want answered is, what’s killing them? New research published today by a global team of researchers, based at the International Centre for Radio Astronomy Research (ICRAR), seeks to answer that question. The study reveals that a phenomenon called ram-pressure stripping is more prevalent than previously thought, driving gas from galaxies and sending them to an early death by depriving them of the material to make new stars. The study of 11,000 galaxies shows their gas—the lifeblood for star formation—is being violently stripped away on...

    THE American space agency is planning to send a spacecraft to a lump of metal in space worth quadrillions of dollars. The 200km-wide asteroid is currently orbiting the sun between Mars and Jupiter. It is made up of various precious metals such as iron, nickel and gold. Experts believe the iron alone in the rock would be worth $10,000 quadrillion – enough to cause the world’s economy, worth $73.7 trillion, to promptly collapse altogether.

Just after entering orbit around Venus in 2015, the Akatsuki orbiter observed a bow-shaped feature in the upper atmosphere over several days. Curiously, the bright structure - which stretched for 10,000km - remained stationary at the altitude of Venus' cloud tops. This is difficult to reconcile with what we know about Venus' thick upper atmosphere, in which clouds streak by at 100 metres per second (m/s). The clouds travel much faster than the slowly rotating planet below, where a Venusian day lasts longer than...

    Once we discovered that the Universe was expanding, the next scientific step was to determine what the rate of expansion was. Despite the fact that it's been more than 80 years, we still don't have agreement on how fast that rate actually is. By looking at the largest cosmic scales and the oldest signals -- the leftover radiation from the Big Bang and the largest-scale galaxy correlations -- we get one number for the rate: 67 km/s/Mpc. But if we look at individual stars, galaxies, supernovae and other direct indicators, we get another number: 74 km/s/Mpc. The uncertainties are very...

    Monday at 7:47 A.M. EST, an asteroid passed by Earth at about half the distance between our planet and the Moon—roughly 119,500 miles, reports Mike Wall at Space.com. The space rock, dubbed 2017 AG13 was on the "smallish" size as far as asteroids go, Wall reports, thought to be between 36 and 111 feet wide. But the most interesting thing about this near miss is that astronomers didn't spot the space rock till Saturday. It managed to fly under the radar for so long because the asteroid was fairly dim and moving fast (roughly ten miles per second). But just...

    Currently, the leading theory of the creation of the Moon is that it formed from a giant impact between a very early Earth and another Mars-sized planet. Yet new research from the Weizmann Institute of Science in Israel has put forward a theory that the Moon may have actually formed from a series of large impacts, rather than just one. The study, published in the journal Nature Geoscience, explains why the Moon appears to be made mostly from Earth-like materials, rather than a mixture of our elements and those of another mystery planet.

    Sunbeams—what a drag. That’s the conclusion of physicists trying to solve a longstanding mystery: why the sun’s surface rotates more slowly than its inner core. The team argues that energy radiating outward from the sun pushes back slightly as it is expelled, providing just enough resistance to put on the brakes. The hypothesis is supported by a new observation: that the thin “skin” of the sun rotates more slowly than layers just beneath. “I really can’t believe nobody has thought of this,” says Hugh Hudson, a solar physicist at the University of California, Berkeley, who was not involved in the...

    In a recent survey of mini-spiral galaxies, astronomers found a unexpected relationship between dark and light matter. The relationship is easy to measure yet impossible to explain using the Standard Model of physics. Researchers from Italy's International School for Advanced Studies conducted a statistical analysis of three dozen mini-spiral galaxies. Their work revealed a strong correlation between the organization of dark and regular matter in each galaxy. If, for example, ordinary matter was condensed at the center of a mini-spiral galaxy, so too was dark matter. If the bulk of regular matter was scattered across the outskirts of the galaxy,...

    Dawn’s Gamma Ray and Neutron Detector (GRaND) determined the concentrations of hydrogen, iron and potassium in Ceres crust. In so doing, it was able to place constraints on the planet’s ice content, and how the surface was likely altered by liquid water in Ceres’ interior. In short, the GRaND instrument detected high levels of hydrogen in Ceres’ uppermost structure (10% by weight), which appeared most prominently around the mid-latitudes. These readings were consistent with broad expanses of water ice. The GRaND data also showed that rather than consisting of a solid ice layer, the ice was likely to take the...

All in all, this makes the sun bear a striking resemblance to Frasier Crane or perhaps your father. The smiley sun photo was first pointed out on Twitter by solar scientist Karl Battams after the Solar Dynamics Observatory's website was updated with the new...

    Astronomers have set a new record, taking the measure of a tiny space rock just 6 feet wide. The researchers used four different telescopes on Earth to study the near-Earth asteroid (NEA), which is called 2015 TC25, during a close flyby it made of the planet in October 2015. "This is the first time we have optical, infrared and radar data on such a small asteroid, which is essentially a meteoroid," Vishnu Reddy, of the University of Arizona's Lunar and Planetary Laboratory, said in a statement. "You can think of it as a meteorite floating in space that hasn't hit...

    THERE is a one in eight chance that the Earth will be hit by a huge solar storm by 2020 which could potentially leave the world without Internet, phone service and many more services that modern-day humans rely on. Researchers have warned that there is roughly a 12 per cent chance that a solar storm could smash into Earth by the end of the decade.(emphasis mine) The powerful event would likely be as huge as the Carrington Event, which occurred on 1859. The solar storm which hit 150 years ago was so powerful that its southern auroras could be seen...

    The European Space Agency's new Mars orbiter just sent back its first high-resolution images of the Red Planet, and the view is amazing. The ExoMars Trace Gas Orbiter (TGO) arrived at Mars on Oct. 19, when its companion spacecraft Schiaparelli crash-landed on the planet's surface. Since then, TGO has been circling Mars, testing out its machinery, and taking spectacularly sharp pictures of the landscape using its Colour and Stereo Surface Imaging System (CaSSIS). ESA stitched together the best of these photos in a cool new flyover video. "The first images we received are absolutely spectacular ― and it was only...
  • Variable, Not Constant: Speed Of Light Theory Challenging Einstein’s Physics Can Now Be Tested

    Researchers suggesting that the speed of light varies have come up with a numerical prediction that will allow their theory to be tested. Many theories in physics are built upon the idea that the speed of light is at a constant rate, but João Magueijo and Niayesh Afshordi think otherwise. In a paper published in the journal Physical Review D, they detailed the creation of an exact figure on the spectral index, a model that can be used to determine if their theory is valid or not. All structures in the universe today were created when fluctuations occurred in the...

    ydonia was first photographed by the Viking 1 and 2 orbiters. Between the two, eighteen images were taken of the region, all of which were of limited resolution. Of these, only five were considered suitable for studying surface features. Because of their limited quality, a particular mesa resembled a humanoid face (see below). It would be another 20 years before other spacecraft photographed the region as they conducted observations of Mars. These included NASA’s Mars Global Surveyor, which orbited Mars from 1997 to 2006; the Mars Reconnaissance Orbiter (MRO), which reached the planet in 2006 and is still in operation;...

    On November 30, Cassini will begin a phase of the mission that the science team calls “Cassini’s Ring-Grazing Orbits,” as the spacecraft will start skimming past the outer edge of the rings, coming within – at times — 4,850 miles (7,800 kilometers) of the rings. ... Between November 30, 2016 and April 22, 2017 Cassini will circle high over and under the poles of Saturn, diving every seven days for a total of 20 times through the unexplored region at the outer edge of the main rings. During the close passes, Cassini’s instruments will attempt to directly sample the icy...

    The full moon of November 14, 2016 is not only the biggest, closest and brightest supermoon of this year. It’s the closest supermoon since January 26, 1948. Should you watch for this full moon on the night of November 14? Sure, and, if you do, it’ll be beautiful. But, for us in the Americas the moon is closer to full on the night of November 13. The moon turns precisely full on November 14, 2016 at 13:52 UTC. This full moon instant will happen in the morning hours before sunrise November 14 in western North America and on many Pacific...

    2. Scout the location carefully Use every tool possible to get the perfect shot, including Google Maps and compasses, to help you locate a spot where you'll be able to see the moon as well as the reference object you want to include. That may mean learning how to read a map, and finding out where the moon will appear on the horizon based on your location. If possible, travel to an area far from city lights to avoid light pollution. And make sure to be precise; Ingalls said he recalls setting up near Washington, D.C.'s Iwo Jima monument hundreds...

    Coronagraphic High Angular Resolution Imaging Spectrograph (CHARIS) has captured the light from one of those exoplanets. This has the researchers excited about what they can see. CHARIS allows astronomers to isolate light reflecting from planets. That’s difficult to do, since they are so much dimmer than the stars they orbit. CHARIS is able to isolate the reflective light from planets larger than Jupiter. Then astronomers can analyze that light to learn about the planet’s age, atmospheric composition, and its size. ... CHARIS was designed and built by a team led by N. Jeremy Kasdin, a professor of mechanical and aerospace...
