    Karoo’s HERA radio telescope attracts even more international funding – SKA SA
    http://www.ska.ac.za/...leases/karoos-hera-radio-telescope-attracts-even-more-international-funding/

    The Hydrogen Epoch of Reionization Array (HERA) radio telescope, located only a few kilometres from the MeerKAT radio telescope, was awarded
    a grant from the Gordon and Betty Moore Foundation in the US to the value of $5.8 million, equivalent to approximately R75 million.

    The construction of HERA started in 2015 and already 35 of the 14-metre diameter dishes have been erected. In September 2016, the National Science Foundation
    (NSF) invested $9.5 million (equivalent to approximately R124 million) in the project and HERA was granted the status of a Square Kilometre Array (SKA) precursor
    telescope. The NSF funding allowed the array to expand to 240 radio dishes by 2018. This additional funding injection from the Gordon and Betty Moore Foundation
    will allow HERA to expand even further to 350 dishes.

    This innovative radio telescope will be instrumental in detecting the distinctive signature that would allow astronomers to understand the formation and evolution
    of the very first luminous sources: the first stars and galaxies in the Universe – a period the scientists call the Epoch of Reionization (EoR).

    Why is NASA going to visit the giant metal asteroid 16 Psyche? - Science News - ABC News (Australian Broadcasting Corporation)
    http://www.abc.net.au/...017-03-06/16-psyche-asteroid-like-no-other-metal-world-nasa-mission/8316054

    Hiding in the belt of frozen rocks between Mars and Jupiter is a body like nothing else in the solar system. The odds of it even existing are tiny.
    Its name is 16 Psyche. At 210 kilometres wide, it is easily one of the bigger asteroids, but Psyche's stand-out feature is that it is made almost entirely of metal.
    That is so unusual that NASA is funding a seven-year mission to visit the asteroid with a robotic spacecraft and study it in detail.

    This view looks toward the anti-Saturn hemisphere of Enceladus. North on Enceladus is up and rotated 4 degrees to the right.
    The image was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 27, 2016.

    The view was obtained at a distance of approximately 41,000 miles (66,000 kilometers) from Enceladus. Image scale is 1,310 feet (398 meters) per pixel.

    Star clusters discovery could upset the astronomical applecart
    https://phys.org/news/2017-03-star-clusters-discovery-astronomical-applecart.html

    The discovery of young stars in old star clusters could send scientists back to the drawing board for one of the Universe's most common objects.

    Dr Bi-Qing For, from the International Centre for Radio Astronomy Research in Perth, said our understanding of how stars evolve is a cornerstone of astronomical science.

    "There are a billion trillion stars in the Universe and we've been observing and classifying those we can see for more than a century," she said.
    "Our models of stellar evolution are based on the assumption that stars within star clusters formed from the same material at roughly the same time."

    Gravity Wave Detection with Atomic Clockssu201709 | www.cfa.harvard.edu/
    https://www.cfa.harvard.edu/news/su201709

    The recent detection of gravitation waves (GW) from the merger of two black holes of about thirty solar-masses each with the ground-based LIGO facility
    has generated renewed enthusiasm for developing even more sensitive measurement techniques. Ground-based GW instruments have widely spaced sensors
    that can detect sub-microscopic changes in their separation -- better than one part in a billion trillion, They suffer, however, from the noise produced by
    small ground tremors -- vibrations from natural or man-made sources that ripple through the precisely tuned detectors. The vibrations most difficult to
    compensate for are those that change relatively slowly, at frequencies around once a second or less, yet astronomers predict that GW sources producing
    these slow variations should be interesting and abundant, from compact stellar-mass binary stars to gravitational events in the early universe.

    Synthetic biology to help colonize Mars
    https://phys.org/news/2017-03-synthetic-biology-colonize-mars.html

    Shannon Dangle finished her PhD ready to take on a new challenge and set her sights on research to help make Mars colonization possible.
    But she isn't pursuing research on rocket fuels or space suits. She's using synthetic biology to improve biomanufacturing of needed resources
    using simple inputs like sunlight, water, and CO2.
