  • Astronomers strike cosmic gold, confirm origin of precious metals in neutron star mergers
    on October 16, 2017 at 2:28 pm

    What many thought would be a long way off, the detection of gravitational waves from the merger of binary neutron stars, actually happened on Aug. 17. The observation of a blue and then red glow from the radioactive debris cloud left behind matched simulations of what the merger should look like, proving that such mergers are the source of most of the very heavy elements in the universe, including gold. […]

  • Scientists discover more about the ingredients for star formation
    on October 10, 2017 at 2:58 pm

    In the local universe close to us, about 70 percent of the hydrogen gas is found in individual atoms, while the rest is in molecules. Astronomers had expected that as they looked back in time, younger galaxies would contain more and more molecular hydrogen until it dominated the gas in the galaxy. Instead, they found that atomic hydrogen makes up the majority of gas in younger galaxies too. […]

  • Is the Milky Way an 'outlier' galaxy? Studying its 'siblings' for clues
    on September 20, 2017 at 3:33 pm

    The most-studied galaxy in the universe -- the Milky Way -- might not be as 'typical' as previously thought, according to a new study. Early results from the Satellites Around Galactic Analogs (SAGA) Survey indicate that the Milky Way's satellites are much more tranquil than other systems of comparable luminosity and environment. Many satellites of those 'sibling' galaxies are actively pumping out new stars, but the Milky Way's satellites are mostly inert. […]

  • New evidence for small, short-lived drops of early universe quark-gluon plasma?
    on September 18, 2017 at 1:30 pm

    Particles emerging from even the lowest energy collisions of small deuterons with large heavy nuclei at the Relativistic Heavy Ion Collider exhibit behavior scientists associate with the formation of a soup of quarks and gluons, the fundamental building blocks of nearly all visible matter. […]

  • Light on exoplanets may be quite different from Earth: Different photosynthesis?
    on September 15, 2017 at 9:00 pm

    Researchers have proposed a prediction that red-edge could be observed as on the Earth even on exoplanets around M-dwarfs. They pointed out that the first oxgenic photorophs are most likely to have evolved underwater to utilize visible light just like what had happened in the primordial ocean on the Earth. They examined light adaptation mechanisms of visible- and IR-radiation-using phototrophs required for adapting to land habitats and found out that IR-using phototrophs struggle to adapt to changing light condition at the boundary of water and land surface.
