    LIGO detects Gravitational Waves for 3rd time: Results confirm new population of black holes

    June 2, 2017, Categories  Astronomy/Space

    This artist's conception shows two merging black holes similar to those detected by LIGO. The black holes are spinning in a nonaligned fashion, which means they have different orientations relative to the overall orbital motion of the pair. LIGO found hints that at least one black hole in the system called GW170104 was nonaligned with its orbital motion before it merged with its partner.

    The Laser Interferometer Gravitational-wave Observatory (LIGO) has made a third detection of gravitational waves, ripples in space and time, demonstrating that a new window in astronomy has been firmly opened. As was the case with the first two detections, the waves were generated when 2 black holes collided to form a larger black hole...

    A giant gas planet – up to 50X the mass of Jupiter, encircled by a ring of dust – is likely hurtling around a star >1000 light years away from Earth, according to new research by an international team of astronomers, led by the University of Warwick. Hugh Osborn, a researcher from Warwick’s Astrophysics Group, has identified that the light from this rare young star is regularly blocked by a large object – and predicts that these eclipses are caused by the orbit of this as-yet undiscovered planet.

    Using data from the Wide Angle Search for Planets (WASP) and Kilodegree Extremely Little Telescope (KELT), Osborn and fellow researchers from Harvard University, Vanderbilt University, and Leiden O...

    Frost on moon’s surface: New evidence

    June 1, 2017, Categories  Astronomy/Space

    In craters near the south pole of the moon, NASA's Lunar Reconnaissance Orbiter found some bright areas and some very cold areas. In areas that are both bright and cold, water ice may be present on the surface as frost. Credit: NASA's Goddard Space Flight Center/Scientific Visualization Studio

    Scientists using data from NASA’s Lunar Reconnaissance Orbiter, or LRO, have identified bright areas in craters near the moon’s south pole that are cold enough to have frost present on the surface. The new evidence comes from an analysis that combined surface temperatures with information about how much light is reflected off the moon’s surface.
     
    “We found that the coldest places near the moon’s south pole are also the brightest places – brighter than we would expect from soil alone – and...

    Cassini finds Saturn’s moon Enceladus may have tipped over

    May 31, 2017, Categories  Astronomy/Space

    Working with image data from NASA's Cassini mission, researchers have found evidence that Saturn's moon Enceladus may have tipped over, reorienting itself so that terrain closer to its original equator was relocated to the poles. This phenomenon is known as true polar wander. Credits: NASA/JPL-Caltech/Space Science Institute/Cornell University

    Saturn’s icy, ocean-bearing moon Enceladus may have tipped over in the distant past, according to recent research from NASA’s Cassini mission. Researchers found evidence that the moon’s spin axis—the line through the north and south poles—has reoriented, possibly due to a collision with a smaller body, such as an asteroid...
