  • Astronomers find a cosmic Titan in the early universe
    on October 17, 2018 at 3:10 pm

    Astronomers have discovered a titanic structure in the early universe, just two billion years after the Big Bang. This galaxy proto-supercluster, nicknamed Hyperion, is the largest and most massive structure yet found at such a remote time and distance. […]

  • Plant hormone makes space farming a possibility
    on October 17, 2018 at 1:49 pm

    With scarce nutrients and weak gravity, growing potatoes on the Moon or on other planets seems unimaginable. But the plant hormone strigolactone could make it possible, plant biologists have shown. The hormone supports the symbiosis between fungi and plant roots, thus encouraging plants' growth -- even under the challenging conditions found in space. […]

  • Supermassive black holes and supercomputers
    on October 17, 2018 at 12:08 pm

    The universe's deep past is beyond the reach of even the mighty Hubble Space Telescope. But a new review explains how creation of the first stars and galaxies is nevertheless being mapped in detail, with the aid of computer simulations and theoretical models -- and how a new generation of supercomputers and software is being built that will fill in the gaps. […]

  • All in the family: Kin of gravitational wave source discovered
    on October 16, 2018 at 5:20 pm

    According to new research, an object named GRB150101B -- first reported as a gamma-ray burst in 2015 -- shares remarkable similarities with GW170817, the neutron star merger discovered by LIGO and observed by multiple light-gathering telescopes in 2017. The new analysis suggests that these two separate objects may in fact be directly related. […]

  • Giant planets around young star raise questions about how planets form
    on October 15, 2018 at 2:45 pm

    Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The system has also set a new record for the most extreme range of orbits yet observed: the outermost planet is more than a thousand times further from the star than the innermost one, which raises interesting questions about how such a system might have formed. […]

  • Death of a massive star and birth of compact neutron star binary
    on October 11, 2018 at 6:31 pm

    The unexpectedly gentle death of a massive star suggests that it was being robbed by a dense companion lurking out of sight. […]

  • New telescope almost doubles known number of mysterious 'fast radio bursts'
    on October 10, 2018 at 5:23 pm

    Astronomers have nearly doubled the known number of 'fast radio bursts'-- powerful flashes of radio waves from deep space. The team's discoveries include the closest and brightest fast radio bursts ever detected and they have proved that fast radio bursts are coming from the other side of the Universe rather than from our own galactic neighborhood. […]

  • Mystery at the center of the Milky Way solved
    on October 10, 2018 at 1:36 pm

    Astronomers have now found the explanation to a recent mystery at the center of the Milky Way galaxy: the high levels of scandium discovered last spring near the galaxy's giant black hole were in fact an optical illusion. […]

  • The stuff that planets are made of
    on October 9, 2018 at 5:59 pm

    Researchers have analyzed the composition and structure of faraway exoplanets using statistical tools. Their analysis indicates whether a planet is earth-like, made up of pure rock or a water-world. The larger the planet, the more hydrogen and helium surround it. […]

  • Lunar craters named in honor of Apollo 8
    on October 5, 2018 at 3:14 pm

    The Working Group for Planetary System Nomenclature of the International Astronomical Union has today officially approved the naming of two craters on the Moon to commemorate the 50th anniversary of the Apollo 8 mission. The names are Anders's Earthrise and 8 Homeward. […]

  • Surprising chemical complexity of Saturn's rings changing planet's upper atmosphere
    on October 4, 2018 at 6:39 pm

    A new study based on data from the final orbits last year of NASA's Cassini spacecraft shows the rings of Saturn -- some of the most visually stupendous objects in the universe -- are far more chemically complicated than previously was understood. […]

  • Observations challenge cosmological theories
    on October 4, 2018 at 5:18 pm

    Since the big bang, fewer galaxy clusters have formed over time than was actually expected. Physicists from the have now confirmed this phenomenon. For the next years the researchers will analyze their data in even greater detail. This will put them in a position to confirm whether the theories considered valid today need to be reworked. […]

  • Newly detected microquasar gamma-rays 'call for new ideas'
    on October 4, 2018 at 5:18 pm

    The first-ever detection of highly energetic radiation from a microquasar has astrophysicists scrambling for new theories to explain the extreme particle acceleration. A microquasar is a black hole that gobbles up debris from a nearby companion star and blasts out powerful jets of material. […]

  • Scientists develop a new way to remotely measure Earth's magnetic field
    on October 4, 2018 at 1:59 pm

    By zapping a layer of meteor residue in the atmosphere with ground-based lasers, scientists are getting a new view of Earth's magnetic field. […]

  • Astronomers find first compelling evidence for a moon outside our solar system
    on October 3, 2018 at 6:29 pm

  • Mountaintop observatory sees gamma rays from exotic Milky Way object
    on October 3, 2018 at 5:44 pm

    The High-Altitude Water Cherenkov Gamma-Ray Observatory (HAWC) collaboration has detected highly energetic light coming from a microquasar -- a black hole that gobbles up stuff from a companion star and blasts out powerful jets of material. Data analysis indicates that electron acceleration and collisions at the ends of the microquasar's jets produced powerful gamma rays. Multi-wavelength messengers from this unusual microquasar may offer scientists a glimpse into more extreme events happening in distant galaxies. […]

  • Did key building blocks for life come from deep space?
    on September 28, 2018 at 5:14 pm

    All living beings need cells and energy to replicate. Without these fundamental building blocks, living organisms could not exist. Little was known about a key element in the building blocks, phosphates, until now. Researchers have now provide compelling new evidence that this component for life was generated in outer space and delivered to Earth in its first one billion years by meteorites or comets. […]

    on September 26, 2018 at 6:08 pm

    Solar energy absorption by methane is 10 times stronger over desert regions such as the Sahara Desert and Arabian Peninsula than elsewhere on Earth, and nearly three times more powerful in the presence of clouds. Researchers came to this conclusion after evaluating observations of Jupiter and Saturn's moon Titan. […]
