  • Harvesting renewable energy from the sun and outer space at the same time
    on November 8, 2018 at 7:24 pm

    Scientists have demonstrated for the first time that heat from the sun and coldness from outer space can be collected simultaneously with a single device. Their research suggests that devices for harvesting solar and space energy will not compete for land space and can actually help each other function more efficiently. […]

  • Magnetic pumping pushes plasma particles to high energies
    on November 5, 2018 at 3:54 pm

    The solar wind is not a calm summer breeze. Instead, it is a roiling, chaotic mess of turbulence and waves. There is a lot of energy stored in this turbulence, so scientists have long thought that it heats the solar wind. However, the heating expected from turbulence is not the heating observed. Scientists now have a new idea about what heats the solar wind, a theory called magnetic pumping. […]

  • A stellar achievement: Magnetized space winds in the laboratory
    on November 5, 2018 at 3:54 pm

    New insights have been gained about stellar winds, streams of high-speed charged particles called plasma that blow through interstellar space. These winds, created by eruptions from stars or stellar explosions, carry with them strong magnetic fields which can interact with or effect other magnetic fields, such as those that surround planets like Earth. To understand these processes, researchers are employing laboratory experiments to study magnetic flows up close. […]

  • Most detailed observations of material orbiting close to a black hole
    on October 31, 2018 at 12:06 pm

    ESO's exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the center of the Milky Way. New observations show clumps of gas swirling around at about 30 percent of the speed of light on a circular orbit just outside its event horizon -- the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole. […]

  • Rare blue asteroid reveals itself during fly-by
    on October 29, 2018 at 7:28 pm

    Blue asteroids are rare, and blue comets are almost unheard of. An international team investigated (3200) Phaethon, a bizarre asteroid that sometimes behaves like a comet, and found it even more enigmatic than previously thought. […]

  • New composite material that can cool itself down under extreme temperatures

    A cutting-edge material, inspired by nature, that can regulate its own temperature and could equally be used to treat burns and help space capsules withstand atmospheric forces is under development. […]

  • A first 'snapshot' of the complete spectrum of neutrinos emitted by the sun
    on October 24, 2018 at 5:14 pm

    About 99 percent of the sun's energy emitted as neutrinos is produced through nuclear reaction sequences initiated by proton-proton (pp) fusion in which hydrogen is converted into helium, say scientists. […]

  • Superflares from young red dwarf stars imperil planets
    on October 18, 2018 at 6:12 pm

    Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their stars. […]

  • School students identify sounds caused by solar storm
    on October 17, 2018 at 1:49 pm

    School students have successfully identified sounds caused by a solar storm in the Earth's magnetic shield.

They found that this event occurred after a Coronal Mass Ejection or 'solar storm' caused a great disturbance to Earth's space environment. […]

  • A break from the buzz: Bees go silent during total solar eclipse
    on October 10, 2018 at 2:55 pm

    In an unprecedented study of a solar eclipse's influence on bee behavior, researchers organized citizen scientists and elementary school classrooms to set up acoustic monitoring stations to listen in on bees' buzzing -- or lack thereof -- as the August 2017 total solar eclipse passed over North America. The results were clear and consistent at locations across the United States: Bees stopped flying during the period of total solar eclipse. […]
