As neighborhood and city planners design ways to reuse vacant land in cities like Detroit, a researcher is urging them to look at the footpaths of people who already live there — literally.
Read moreA new model for plasma flow within the sun provides novel explanations for sunspots, the 11-year sunspot cycle, solar magnetic reversals and other previously unexplained solar phenomena.
Read moreAstronomers observed six mild-mannered LINER galaxies suddenly and surprisingly transforming into ravenous quasars — home to the brightest of all active galactic nuclei. The team's observations could help demystify the nature of both LINERs and quasars while answering some burning questions about galactic evolution. Based on their analysis, the researchers suggest they have discovered an entirely new type of black hole activity at the centers of these six LINER galaxies.
Read moreDark matter is only known by its effect on massive astronomical bodies, but has yet to be directly observed or even identified. A theory about what dark matter might be suggests that it could be a particle called an axion and that these could be detectable with laser-based experiments that already exist. These laser experiments are gravitational-wave observatories.
Read moreNo one knows for certain when Saturn's iconic rings formed, but a new study suggests that they are much older than some scientists think.
Read morePhysicists and computer scientists have developed a new approach to the problem of dark matter and dark energy in the universe. Using machine learning tools, they programmed computers to teach themselves how to extract the relevant information from maps of the universe.
Read moreAstronomers have discovered the most massive neutron star to date, a rapidly spinning pulsar approximately 4,600 light-years from Earth. This record-breaking object is teetering on the edge of existence, approaching the theoretical maximum mass possible for a neutron star.
Read moreThe overall brightness of Tabby's Star has been gradually dimming for years. A new study suggests chunks of an exomoon's dusty outer layers of ice, gas and carbonaceous rock may be accumulating in a disk, blocking the star's light and making it appear to slowly fade.
