    on June 1, 2017 at 7:18 pm

    Scientists working with the LIGO Scientific Collaboration measured and interpreted the spin and alignment of a newly formed black hole detected on Jan. 4 by LIGO. The team also simulated the gravitational wave signal produced in the collision that formed the new black hole. […]

  • 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

    Astronomers have put a basic principle of black holes to the test, showing that matter completely vanishes when pulled in. Their results constitute another successful test for Albert Einstein's General Theory of Relativity. […]

  • The big star that couldn't become a supernova
    on May 25, 2017 at 6:15 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. […]

The study enriches scientists' understanding of the universe on the largest scale. […]

  • Mysterious cosmic explosion surprises astronomers studying the distant X-ray universe
    on March 30, 2017 at 5:24 pm

    A mysterious flash of X-rays has been discovered by NASA's Chandra X-ray Observatory in the deepest X-ray image ever obtained. This source likely comes from some sort of destructive event, but it may be of a variety that scientists have never seen before. […]

  • Stars born in winds from supermassive black holes
    on March 27, 2017 at 3:46 pm

    Observations using ESO's Very Large Telescope have revealed stars forming within powerful outflows of material blasted out from supermassive black holes at the cores of galaxies. These are the first confirmed observations of stars forming in this kind of extreme environment. The discovery has many consequences for understanding galaxy properties and evolution. […]

  • Radiation from nearby galaxies helped fuel first monster black holes
    on March 13, 2017 at 5:50 pm

    Researchers have shown how supermassive black holes may have formed in the early universe. They suggest that radiation from a neighboring galaxy could have shut down star-formation in a black-hole hosting galaxy, allowing the nascent black hole to rapidly put on weight. […]

  • Hubble dates black hole's last big meal
    on March 9, 2017 at 6:27 pm

    NASA's Hubble Space Telescope has found that the black hole at the center of our Milky Way galaxy ate its last big meal about 6 million years ago, when it consumed a large clump of infalling gas. After the meal, the engorged black hole burped out a colossal bubble of gas weighing the equivalent of millions of suns, which now billows above and below our galaxy's center. […]

  • New survey finds 'Peter Pan' radio galaxies that may never grow up
    on March 8, 2017 at 5:18 pm

    A team of astronomers has doubled the number of known young, compact radio galaxies -- galaxies powered by newly energized black holes. The improved tally will help astronomers understand the relationship between the size of these radio sources and their age, as well as the nature of the galaxy itself. In particular, it will help astronomers understand why there are so many more young radio galaxies than old. […]

  • Rapid changes point to origin of ultra-fast black hole 'burp'
    on March 1, 2017 at 6:20 pm

    Scientists have made the most detailed observation yet of a black hole outflow, from the active galaxy IRAS 13224-3809. The outflow's temperature changed on time scales of less than an hour -- hundreds of times faster than ever seen before. The rapid fluctuations in the outflow's temperature also indicated that the outflow was responding to X-ray emissions from the accretion disk, a dense zone of gas and other materials that surrounds the black hole. […]

  • Scientists reach back in time to discover some of the most power-packed galaxies
    on February 28, 2017 at 1:43 pm

    When the universe was young, a supermassive black hole heaved out a jet of particle-infused energy that raced through space at nearly the speed of light. Billions of years later, scientists has identified this black hole and four others similar to it that range in age from 1.4 billion to 1.9 billion years old. […]
