  • Supermassive black holes feed on cosmic jellyfish
    on August 16, 2017 at 5:46 pm

    Observations of 'Jellyfish galaxies' with ESO's Very Large Telescope have revealed a previously unknown way to fuel supermassive black holes. It seems the mechanism that produces the tentacles of gas and newborn stars that give these galaxies their nickname also makes it possible for the gas to reach the central regions of the galaxies, feeding the black hole that lurks in each of them and causing it to shine brilliantly. […]

  • Cosmic magnifying lens reveals inner jets of black holes
    on August 15, 2017 at 5:38 pm

  • Black holes pervade the universe, celestial census indicates
    on August 7, 2017 at 7:54 pm

    After conducting a cosmic inventory of sorts to calculate and categorize stellar-remnant black holes, astronomers have concluded that there are probably tens of millions of the enigmatic, dark objects in the Milky Way -- far more than expected. […]

  • Primordial black holes may have helped to forge heavy elements
    on August 4, 2017 at 5:18 pm

    Astronomers like to say we are the byproducts of stars, stellar furnaces that long ago fused hydrogen and helium into the elements needed for life through the process of stellar nucleosynthesis. But what about the heavier elements in the periodic chart, elements such as gold, platinum and uranium? Astronomers believe most of these "r-process elements" -- elements much heavier than iron -- were created, either in the aftermath of the collapse of massive stars and the associated supernova explosions, or in the merging of binary neutron star systems. […]

  • New simulations could help in hunt for massive mergers of neutron stars, black holes
    on August 2, 2017 at 5:47 pm

  • Gamma-ray burst captured in unprecedented detail
    on July 26, 2017 at 5:21 pm

    Gamma-ray bursts are among the most energetic and explosive events in the universe. They are also short-lived, lasting from a few milliseconds to about a minute. This has made it tough for astronomers to observe a gamma-ray burst in detail. Using a wide array of ground- and space-based telescope observations, astronomers constructed one of the most detailed descriptions of a gamma-ray burst to date. […]

  • Hubble eyes a powerful galaxy with a password name
    on June 30, 2017 at 2:48 pm

    Not all galaxies have the luxury of possessing a simple moniker or quirky nickname. This impressive galaxy imaged by the NASA/ESA Hubble Space Telescope is one of the unlucky ones, and goes by a name that looks more like a password for a computer: 2XMM J143450.5+033843. […]

  • Astronomers detect orbital motion in pair of supermassive black holes
    on June 27, 2017 at 3:48 pm

  • LIGO detects gravitational waves for third time
    on June 1, 2017 at 4:39 pm

    The Laser Interferometer Gravitational-wave Observatory has made a third detection of gravitational waves, ripples in space and time, demonstrating that a new window in astronomy has been firmly opened. As was the case with the first two detections, the waves were generated when two black holes collided to form a larger black hole. […]

  • X-ray pulses create 'molecular black hole'
    on May 31, 2017 at 5:33 pm

    Scientists have used an ultra-bright pulse of X-ray light to turn an atom in a molecule briefly into a sort of electromagnetic black hole. Unlike a black hole in space, the X-rayed atom does not draw in matter from its surroundings through the force of gravity, but electrons with its electrical charge -- causing the molecule to explode within the tiniest fraction of a second. The study provides important information for analyzing biomolecules using X-ray lasers. […]

  • Do stars fall quietly into black holes, or crash into something utterly unknown?
    on May 30, 2017 at 3:51 pm

  • Using math to investigate possibility of time travel
    on April 27, 2017 at 1:17 pm

    After some serious number crunching, a researcher says that he has come up with a mathematical model for a viable time machine: a Traversable Acausal Retrograde Domain in Space-time (TARDIS). He describes it as a bubble of space-time geometry which carries its contents backward and forwards through space and time as it tours a large circular path. The bubble moves through space-time at speeds greater than the speed of light at times, allowing it to move backward in time. […]

  • Supermassive black holes found in two tiny galaxies
    on April 17, 2017 at 6:49 pm

    Astronomers have found two ultra-compact dwarf galaxies with supermassive black holes, the second and third such galaxies found to harbor the objects. Together, the three examples suggest that black holes lurk at the center of most ultra-compact dwarfs, potentially doubling the number of supermassive black holes known in the universe. The tiny galaxies were likely leftovers of larger galaxies stripped of their outer layers after colliding into other, larger galaxies. […]
