  • Apollo astronauts experiencing higher rates of cardiovascular-related deaths
    28 July 2016, 4:22 pm
    Members of the successful Apollo space program are experiencing higher rates of cardiovascular problems that are thought to be caused by their exposure to deep space radiation, according to a new study.
  • White dwarf lashes red dwarf with mystery ray
    27 July 2016, 8:03 pm
    Astronomers have discovered a new type of exotic binary star: in the system AR Scorpii a rapidly spinning white dwarf star is powering electrons up to almost the speed of light. These high energy particles release blasts of radiation that lash the companion red dwarf star, and cause the entire system to pulse dramatically every 1.97 minutes with radiation ranging from the ultraviolet to radio.
  • Jupiter's great red spot heats planet's upper atmosphere
    27 July 2016, 8:00 pm
    Researchers have discovered that Jupiter's Great Red Spot may provide the mysterious source of energy required to heat the planet's upper atmosphere to the unusually high values observed.
  • Finding the loneliest young star
    27 July 2016, 6:46 pm
    Alone on the cosmic road, far from any known celestial object, a young, independent star is going through a tremendous growth spurt. When a team of scientists examined infrared images of the same area, they realized this object has a lot of warm dust around it, which must have been heated by an outburst. Researchers determined it likely is a young star that has been outbursting for several years.
  • Astronomers uncover hidden stellar birthplace
    27 July 2016, 4:35 pm
    Astronomers have uncovered a hidden stellar birthplace in a nearby spiral galaxy, using a telescope in Chile. The results show that the speed of star formation in the center of the galaxy - and other galaxies like it - may be much higher than previously thought.
  • Did the LIGO gravitational waves originate from primordial black holes?
    27 July 2016, 4:34 pm
    Binary black holes recently discovered by the LIGO-Virgo collaboration could be primordial entities that formed just after the Big Bang, report Japanese astrophysicists. If further data support this observation, it could mark the first confirmed finding of a primordial black hole, guiding theories about the beginnings of the universe.
  • NASA team begins testing of a 'new-fangled' optic
    26 July 2016, 6:38 pm
    t's an age-old astronomical truth: To resolve smaller and smaller physical details of distant celestial objects, scientists need larger and larger light-collecting mirrors. This challenge is not easily overcome given the high cost and impracticality of building and -- in the case of space observatories -- launching large-aperture telescopes.
  • Better defining the signals left by as-yet-undefined dark matter at the LHC
    26 July 2016, 6:37 pm
    Physicists still don't exactly know what dark matter is. Indeed, they can only see its effect in the form of gravity. Now, the high energy physics community has developed a set of simplified models which retain the elegance of the traditional Effective Field Theories-style models yet provide a better description of the signals of dark matter.
  • A famous supermassive black hole 'spied on' with the Gran Telescopio CANARIAS
    26 July 2016, 6:35 pm
    Novel observations by an international group of researchers with the CanariCam instrument on the Gran Telescopio CANARIAS provide new information about magnetic fields around the active nucleus of the galaxy Cygnus A. This is the first time that polarimetric observations in the middle infrared region of the spectrum have been made of the nucleus of an active galaxy.
  • Light shed on a superluminous supernova which appears to have exploded twice
    26 July 2016, 6:34 pm
    An international group of researchers has used the GTC to observe a superluminous supernova almost from the moment it occurred. It has revealed surprising behaviour, because this supernova showed an initial increase in brightness which later declined for a few days, and later increased again much more strongly. The scientists have used the data observed at the GTC and has combined them with other observations to try to explain the origin of the phenomenon.
