  1. Global Aerospace Corporation to present Pluto lander concept to NASA

    09.21 / 21:11 eurekalert.org Eurekalert.org - Astronomy
    (Global Aerospace Corporation) Under a grant from NASA's NIAC program, GAC is developing an integrated 'entrycraft' design that can decelerate and gently land on the surface of Pluto from a speed of over 30,000 mph using only drag from Pluto's ultra-thin atmosphere and just a few pounds of propellant. Once at the surface, the vehicle can switch to 'hopper' mode to hop around the surface, tens or hundreds of kilometers at a time, investigating surface features of…

  3. Earth and Space Science Open preprint server to be powered by AGU and Atypon

    09.21 / 21:11 eurekalert.org Eurekalert.org - Astronomy
    (American Geophysical Union) The American Geophysical Union (AGU) and Atypon announced today a joint initiative to develop Earth and Space Science Open Archive (ESSOAr), a community server for the open dissemination of Earth and space science preprints and rich conference…
  4. NASA measures Hurricane Maria's torrential rainfall, sees eye re-open

    09.21 / 20:14 eurekalert.org Eurekalert.org - Astronomy
    (NASA/Goddard Space Flight Center) Hurricane Maria has caused catastrophic flooding in Puerto Rico and left a wake of heavy rainfall that NASA measured using a fleet of satellites in space. NASA satellite imagery also saw Maria's eye close up as it tracked across Puerto Rico and re-open after its…
  5. Ultra-high-energy cosmic rays come from galaxies far, far away

    09.21 / 19:14 eurekalert.org Eurekalert.org - Astronomy
    (American Association for the Advancement of Science) A new study reveals that cosmic rays with the highest energies that make their way to Earth originated from outside our Milky Way…
  6. Study confirms cosmic rays have extragalactic origins

    09.21 / 19:14 eurekalert.org Eurekalert.org - Astronomy
    (University of Nebraska-Lincoln) International collaboration by scientists with the Pierre Auger Observatory confirms that most of the highest energy cosmic rays that reach the Earth come from outside the Milky Way…
  7. NASA sees large Tropical Storm Jose doing a 'sit and spin' off the Massachusetts coast

    09.21 / 15:21 eurekalert.org Eurekalert.org - Astronomy
    (NASA/Goddard Space Flight Center) Tropical Storm Jose continued to spin south of Massachusetts when NASA's Aqua satellite flew overhead from space and captured an image of the large storm that hasn't moved…
  8. NASA sees Typhoon Doksuri in the South China Sea

    09.14 / 20:02 eurekalert.org Eurekalert.org - Astronomy
    (NASA/Goddard Space Flight Center) Typhoon Doksuri appeared well-rounded and organized on satellite imagery as it moved through the north central South China Sea toward…
  9. Physicists offer explanation for diverse galaxy rotations

    09.14 / 17:53 eurekalert.org Eurekalert.org - Astronomy
    (University of California - Riverside) A University of California, Riverside-led team of physicists has found a simple and viable explanation for the diversity observed in galactic rotations. Hai-Bo Yu and colleagues report that diverse galactic-rotation curves, a graph of rotation speeds at different distances from the center, can be naturally explained if dark matter particles are assumed to strongly collide with one another in the inner halo, close to the galaxy's center -- a process…
  10. NASA-NOAA Satellite spots 2 tails of Hurricane Max

    09.14 / 16:59 eurekalert.org Eurekalert.org - Astronomy
    (NASA/Goddard Space Flight Center) NASA-NOAA's Suomi NPP satellite captured an image of the latest tropical cyclone in the Eastern Pacific on Sept. 13 along the southwestern coast of Mexico. After Max formed as a tropical storm, it appeared to have two "tails." Max strengthened into a hurricane on Sept.…
  11. GOES-West Satellite shows shear in Tropical Depression 15E

    09.14 / 16:59 eurekalert.org Eurekalert.org - Astronomy
    (NASA/Goddard Space Flight Center) NOAA's GOES-West satellite revealed that vertical wind shear is affecting Tropical Depression 15E in the Eastern Pacific…
  12. NASa sees remnants of irma ready to exit Eastern US

    09.14 / 16:59 eurekalert.org Eurekalert.org - Astronomy
    (NASA/Goddard Space Flight Center) NASA's Terra satellite and NOAA's GOES East satellite have been just two of the fleet of satellites monitoring the life and death of former Hurricane Irma. Imagery from both of those satellites over two days show the movement of Irma's remnant…
  13. Hubble observes pitch black planet

    09.14 / 16:59 eurekalert.org Eurekalert.org - Astronomy
    (ESA/Hubble Information Centre) Astronomers have discovered that the well-studied exoplanet WASP-12b reflects almost no light, making it appear essentially pitch black. This discovery sheds new light on the atmospheric composition of the planet and also refutes previous hypotheses about WASP-12b's atmosphere. The results are also in stark contrast to observations of another similarly sized…
  14. NASA's Terra satellite spies Typhoon Talim's large eye

    (NASA/Goddard Space Flight Center) NASA's Terra satellite passed over Typhoon Talim and found a powerful storm with a large, open…
  15. The return of the comet-like exoplanet

    09.14 / 16:00 eurekalert.org Eurekalert.org - Astronomy
    (Université de Genève) Astronomers from UNIGE), also members of the PlanetS, focused the Hubble Space Telescope on an exoplanet that had already been seen losing its atmosphere, which forms an enormous cloud of hydrogen, giving the planet the appearance of a giant comet. During earlier observations, it was not possible to cover the whole cloud, whose shape was predicted by numerical simulations. Thanks to these new observations, the scientists have finally been able to confirm…
