  • Diamond dust shimmering around distant stars
    on June 11, 2018 at 5:38 pm

    Some of the tiniest diamonds in the universe -- bits of crystalline carbon hundreds of thousands of times smaller than a grain of sand -- have been detected swirling around three infant star systems in the Milky Way. These microscopic gemstones are neither rare nor precious; they are, however, exciting for astronomers who identified them as the source of a mysterious cosmic microwave 'glow' emanating from several protoplanetary disks in our galaxy. […]

  • Dark inflation opens up a gravitational window onto the first moments after the Big Bang
    on June 7, 2018 at 2:09 pm

    Dark matter and dark energy may have driven inflation, the exponential expansion of the Universe moments after the Big Bang. A new cosmological model proposed by physicists, which takes dark inflation into account, is the first to outline a precise chronology of the main events during the early history of our Universe. The model makes a spectacular prediction: that it should be possible to detect gravitational waves that were formed just fractions of a second after the creation of spacetime. […]

  • How do you weigh a galaxy? Especially the one you're in?
    on June 6, 2018 at 9:38 pm

    Pinning down the mass of a galaxy may seem like an esoteric undertaking, but scientists think it holds the key to unraveling the nature of the elusive, yet-to-be-seen dark matter, and the fabric of our cosmos. A new technique promises more reliable estimates of the masses of galaxies. […]

    on June 5, 2018 at 9:24 pm

    One of the unsolved mysteries in modern science is why the expansion of the universe appears to be accelerating. As astrophysicists look for answers in the mountains of data gathered from astronomical observations, they are finding that inconsistencies in that data might ultimately lead to the truth. […]

  • Alien apocalypse: Can any civilization make it through climate change?
    on June 4, 2018 at 9:26 pm

    Does the universe contain planets with truly sustainable civilizations? Or does every civilization that may have arisen in the cosmos last only a few centuries before it falls to the climate change it triggers? Astrophysicists have developed a mathematical model to illustrate how a technologically advanced population and its planet might develop together, putting climate change in a cosmic context. […]

  • ALMA and VLT find too many massive stars in starburst galaxies, near and far
    on June 4, 2018 at 3:25 pm

    Astronomers using ALMA and the VLT have discovered that both starburst galaxies in the early Universe and a star-forming region in a nearby galaxy contain a much higher proportion of massive stars than is found in more peaceful galaxies. These findings challenge current ideas about how galaxies evolved, changing our understanding of cosmic star-formation history and the build up of chemical elements. […]

    Globular clusters could be up to 4 billion years younger than previously thought, new research has found. […]

  • Using the K computer, scientists predict exotic 'di-Omega' particle
    on May 24, 2018 at 4:08 pm

    Based on complex simulations of quantum chromodynamics performed using the K computer, one of the most powerful computers in the world, scientists have predicted a new type of 'dibaryon' -- a particle that contains six quarks instead of the usual three. Studying how these elements form could help scientists understand the interactions among elementary particles in extreme environments such as the interiors of neutron stars or the early universe moments after the Big Bang. […]

    For the first time, astronomers have witnessed the birth of a colossal cluster of galaxies. Their observations reveal at least 14 galaxies packed into an area only four times the diameter of the Milky Way's galactic disk. Computer simulations of the galaxies predict that over time the cluster will assemble into one of the most massive structures in the modern universe. […]

  • Uncovering the secret law of the evolution of galaxy clusters
    on April 24, 2018 at 1:37 pm

    Using observational data from the Hubble Space Telescope and the Subaru Telescope, the size and mass of galaxy clusters have precisely been measured. The research team analyzed those data and found a simple law that regulates the growth of the clusters. They also showed that the clusters are still young and growing. The newfound law will serve as a tool to clarify the evolutionary history of clusters and the universe. […]

  • 'Face recognition' for galaxies: Artificial intelligence brings new tools to astronomy
    on April 23, 2018 at 4:51 pm

    A machine learning method called 'deep learning,' which has been widely used in face recognition and other image- and speech-recognition applications, has shown promise in helping astronomers analyze images of galaxies and understand how they form and evolve. In a new study, researchers used computer simulations of galaxy formation to train a deep learning algorithm, which then proved surprisingly good at analyzing images of galaxies from the Hubble Space Telescope.

The new results predict the maximum bandwidth of the universe, which is the maximum speed at which any change can occur in the universe. […]

  • Black hole and stellar winds form giant butterfly, shut down star formation in galaxy
    on April 18, 2018 at 6:15 pm

    Researchers have completed an unprecedented 'dissection' of twin galaxies in the final stages of merging. The new study explores a galaxy called NGC 6240. While most galaxies in the universe hold only one supermassive black hole at their center, NGC 6240 contains two -- and they're circling each other in the last steps before crashing together. […]
