  • Nearly 80 exoplanet candidates identified in record time
    on June 21, 2018 at 4:19 pm

    Scientists have analyzed data from K2, the follow-up mission to NASA's Kepler Space Telescope, and have discovered a trove of possible exoplanets amid some 50,000 stars. The scientists report the discovery of nearly 80 new planetary candidates, including a particular standout: a likely planet that orbits the star HD 73344, which would be the brightest planet host ever discovered by the K2 mission. […]

  • Old star clusters could have been the birthplace of supermassive stars
    on June 21, 2018 at 2:10 pm

    Astrophysicists may have found a solution to a problem that has perplexed scientists for more than 50 years: why are the stars in globular clusters made of material different to other stars found in the Milky Way? […]

  • Best evidence of rare black hole captured
    on June 18, 2018 at 6:18 pm

    Scientists have been able to prove the existence of small black holes and those that are super-massive but the existence of an elusive type of black hole, known as intermediate-mass black holes (IMBHs) is hotly debated. New research shows the strongest evidence to date that this middle-of-the-road black hole exists, by serendipitously capturing one in action devouring an encountering star. […]

  • Hunting molecules to find new planets
    on June 18, 2018 at 3:30 pm

    It's been impossible to obtain images of an exoplanet, so dazzling is the light of its star. However, astronomers have the idea of detecting molecules that are present in the planet's atmosphere in order to make it visible, provided that these same molecules are absent from its star. Thanks to this innovative technique, the device is sensitive to the selected molecules, making the star invisible and allowing the astronomers to observe the planet. […]

  • Distant moons may harbor life
    on June 15, 2018 at 1:36 am

    Researchers have identified more than 100 giant planets that potentially host moons capable of supporting life. Their work will guide the design of future telescopes that can detect these potential moons and look for tell-tale signs of life, called biosignatures, in their atmospheres. […]

  • Short gamma-ray bursts do follow binary neutron star mergers

  • Trio of infant planets discovered around newborn star
    on June 13, 2018 at 2:19 pm

    Two independent teams of astronomers have uncovered convincing evidence that three young planets are in orbit around an infant star known as HD 163296. Using a new planet-finding strategy, the astronomers identified three discrete disturbances in a young star's gas-filled disk: the strongest evidence yet that newly formed planets are in orbit there. […]

  • Discovery of clusters of galaxies in the early universe
    on June 7, 2018 at 2:09 pm

    Until now astronomers thought that these phenomena occurred 3,000 million years after the Big Bang, but this new result shows that they were already happening when the Universe was 1,500 million years old. […]

  • Globular clusters 4 billion years younger than previously thought
    on June 4, 2018 at 3:24 pm

    Globular clusters could be up to 4 billion years younger than previously thought, new research has found. […]

  • Cosmic collision lights up the darkness
    on May 31, 2018 at 3:46 pm

    Though it resembles a peaceful rose swirling in the darkness of the cosmos, NGC 3256 is actually the site of a violent clash. This distorted galaxy is the relic of a collision between two spiral galaxies, estimated to have occured 500 millions years ago. Today it is still reeling in the aftermath of this event. […]

  • Large Magellanic Cloud: A crowded neighborhood
    on May 30, 2018 at 3:31 pm

    Glowing brightly about 160,000 light-years away, the Tarantula Nebula is the most spectacular feature of the Large Magellanic Cloud, a satellite galaxy to our Milky Way. A new image reveals a cosmic landscape of star clusters, glowing gas clouds and the scattered remains of supernova explosions. This is the sharpest image ever of this entire field. […]

  • Unprecedented detail in pulsar 6,500 light-years from Earth
    on May 23, 2018 at 5:32 pm

    A team of astronomers has performed one of the highest resolution observations in astronomical history by observing two intense regions of radiation, 20 kilometers apart, around a star 6,500 light-years away. The observation is equivalent to using a telescope on Earth to see a flea on the surface of Pluto. […]

  • Lightening up dark galaxies
    on May 23, 2018 at 1:13 pm

    Astronomers have identified at least six candidates for dark galaxies -- galaxies that have a few (if any) stars in them and are, for that reason, notoriously difficult to detect with current instruments. […]

    on May 15, 2018 at 8:28 pm

    Aspects of an otherwise Earthlike planet's tilt and orbital dynamics can severely affect its potential habitability -- even triggering abrupt 'snowball states' where oceans freeze and surface life is impossible, according to new research from astronomers. […]

  • What will happen when our sun dies?
    on May 7, 2018 at 3:19 pm

    Scientists agree the sun will die in approximately five billion years, but they weren't sure what would happen next -- until now. A team of international astronomers predicts it will turn into a massive ring of luminous, interstellar gas and dust, known as a planetary nebula. […]

  • Hubble detects helium in the atmosphere of an exoplanet for the first time
    on May 2, 2018 at 5:18 pm

    Astronomers using the NASA/ESA Hubble Space Telescope have detected helium in the atmosphere of the exoplanet WASP-107b. This is the first time this element has been detected in the atmosphere of a planet outside the Solar System. The discovery demonstrates the ability to use infrared spectra to study exoplanet extended atmospheres. […]
