  • Astronomers discover S0-2 star is single and ready for big Einstein test
    on February 22, 2018 at 3:36 pm

    A team of astronomers has found that S0-2 does not have a significant other after all, or at least one that is massive enough to get in the way of critical measurements that astronomers need to test Einstein's Theory of General Relativity. Up until now, it was thought that S0-2 may be a binary, a system where two stars circle around each other. […]

  • Magnetic field traces gas and dust swirling around supermassive black hole
    on February 21, 2018 at 5:29 pm

    Astronomers reveal a new high resolution map of the magnetic field lines in gas and dust swirling around the supermassive black hole at the center of our Galaxy.

  • Some black holes erase your past
    on February 21, 2018 at 2:13 pm

    Physicists insist on determinism: your past and present determine your future uniquely, per Einstein's equations of general relativity. They call this strong cosmic censorship. A mathematician found some types of black holes -- charged, non-rotating objects in an expanding universe -- that allow an observer inside the black hole to travel across a horizon into a place where the past is obliterated and there are an infinite number of possible futures for every initial state. […]

  • No relation between a supermassive black hole and its host galaxy?
    on February 20, 2018 at 5:30 pm

    Using ALMA to observe an active galaxy with a strong ionized gas outflow from the galactic center, a team has obtained a result making astronomers even more puzzled -- the team clearly detected CO gas associated with the galactic disk, yet they have also found that the CO gas which settles in the galaxy is not affected by the strong ionized gas outflow launched from the galactic center. […]

  • 'Ultramassive' black holes discovered in far-off galaxies
    on February 20, 2018 at 2:32 pm

  • Newborns or survivors? The unexpected matter found in hostile black hole winds
    on January 30, 2018 at 5:37 pm

    The existence of large numbers of molecules in winds powered by supermassive black holes at the centers of galaxies has puzzled astronomers since they were discovered more than a decade ago. Molecules trace the coldest parts of space, and black holes are the most energetic phenomena in the universe, so finding molecules in black hole winds was like discovering ice in a furnace. A new theory predicts the molecules are born in the winds with unique properties that enable them to adapt to and thrive in the hostile environment. […]

  • New for three types of extreme-energy space particles: Theory shows unified origin
    on January 22, 2018 at 4:08 pm

    One of the biggest mysteries in astroparticle physics has been the origins of ultrahigh-energy cosmic rays, very high-energy neutrinos, and high-energy gamma rays. Now, a new theoretical model reveals that they all could be shot out into space after cosmic rays are accelerated by powerful jets from supermassive black holes. The model may set a new milestone on the path toward solving the half-century-old enigma of the origin of the highest-energy particles in the universe. […]

  • Black hole spin cranks-up radio volume
    on January 12, 2018 at 2:59 pm

    Statistical analysis of supermassive black holes suggests that the spin of the black hole may play a role in the generation of powerful high-speed jets blasting radio waves. By analyzing nearly 8000 quasars from the Sloan Digital Sky Survey, research team found that the oxygen emissions are 1.5 times stronger in radio loud quasars than in radio quiet quasars. This implies that spin is an important factor in the generation of jets. […]
