  • Macroscopic phenomena governed by microscopic physics
    on December 3, 2018 at 3:14 pm

    Researchers have observed a magnetic reconnection driven by electron dynamics in laser-produced plasmas. Magnetic reconnections are often observed in the magnetic flux on the Sun and the Earth's magnetosphere. It has been highly challenging to reveal the electron scale, microscopic information in the vast universe. Applying a weak magnetic field, where only electrons are directly coupled with the magnetic field, we observed a plasmoid and cusp-like features typical to magnetic reconnections. […]

  • New finding of particle physics may help to explain the absence of antimatter
    on November 13, 2018 at 4:04 pm

    With the help of computer simulations, particle physics researchers may be able to explain why there is more matter than antimatter in the Universe. The simulations offer a new way of examining conditions after the Big Bang, and could provide answers to some fundamental questions in particle physics. […]

  • Astronomers find pairs of black holes at the centers of merging galaxies
    on November 7, 2018 at 6:38 pm

    For the first time, a team of astronomers has observed several pairs of galaxies in the final stages of merging together into single, larger galaxies. Peering through thick walls of gas and dust surrounding the merging galaxies' messy cores, the research team captured pairs of supermassive black holes -- each of which once occupied the center of one of the two original smaller galaxies -- drawing closer together before they coalescence into one giant black hole. […]

  • Cosmic fountain offers clues to how galaxies evolve
    on November 6, 2018 at 3:38 pm

  • 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. […]

  • Laser blasting antimatter into existence
    on November 5, 2018 at 3:54 pm

    Antimatter is an exotic material that vaporizes when it contacts regular matter. If you hit an antimatter baseball with a bat made of regular matter, it would explode in a burst of light. It is rare to find antimatter on Earth, but it is believed to exist in the furthest reaches of the universe. Amazingly, antimatter can be created out of thin air... […]

  • NASA retires Kepler Space Telescope
    on October 31, 2018 at 1:25 pm

    After nine years in deep space collecting data, NASA's Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its current, safe orbit, away from Earth. Kepler leaves a legacy of more than 2,600 planet discoveries from outside our solar system, many of which could be promising places for life. […]

  • New insight into why galaxies stop forming stars
    on October 23, 2018 at 10:54 pm

    Galaxy clusters are rare regions of the universe consisting of hundreds of galaxies containing trillions of stars. It has long been known that when a galaxy falls into a cluster, star formation is fairly rapidly shut off in a process known as 'quenching.' A new study has made the best measurement yet of the quenching timescale, measuring how it varies across 70 percent of the history of the universe. […]

  • Ultra-close stars discovered inside a planetary nebula
    on October 23, 2018 at 5:05 pm

    Astronomers have discovered two stars in a binary pair that complete an orbit around each other in a little over three hours, residing in the planetary nebula M3-1. Remarkably, the stars could drive a nova explosion, an entirely unexpected event based on our current understanding of binary star evolution. […]

  • Gravitational waves could soon accurately measure universe's expansion
    on October 22, 2018 at 8:21 pm

  • Unprecedented look at electron: Size limit for undiscovered subatomic particles determined
    on October 17, 2018 at 6:09 pm

    A new study suggests that many theorized heavy particles, if they exist at all, do not have the properties needed to explain the predominance of matter over antimatter in the universe. If confirmed, the findings would force significant revisions to several prominent theories posed as alternatives to the Standard Model of particle physics, which was developed in the early 1970s. […]

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

  • 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. […]

  • The state of the early universe: The beginning was fluid
    on October 15, 2018 at 3:35 pm

    Scientists recently collided Xenon nuclei, in order to gain new insights into the properties of the Quark-Gluon Plasma (the QGP). The QGP is a special state consisting of the fundamental particles, the quarks, and the particles that bind the quarks together, the gluons. The result was obtained using the ALICE experiment at the superconducting Large Hadron Collider. […]

  • 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. […]

  • The cosmological lithium problem
    on October 9, 2018 at 2:25 pm

    An international research group has tried to find a solution to one of the unknowns in the current description of the Big Bang. Different nuclear reactions responsible for the creation and destruction of atomic nuclei in nucleosynthesis during the Big Bang are crucial in determining the primordial abundance of lithium, the third (and last) chemical element formed during the very early phase of the creation of the universe. […]

  • String theory: Is dark energy even allowed?
    on October 9, 2018 at 2:24 pm

    In string theory, a paradigm shift could be imminent. In June, a team of string theorists published a conjecture which sounded revolutionary: String theory is said to be fundamentally incompatible with our current understanding of 'dark energy'. A new study has now found out that this conjecture seems to be incompatible with the existence of the Higgs particle. […]

  • 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. […]
