  • Finding a planet with a 10 year orbit in just a few months
    on July 18, 2018 at 1:25 pm

    To discover the presence of a planet around stars, astronomers wait until it has completed three orbits. However, this effective technique has its drawbacks since it cannot confirm the presence of planets at relatively long periods. To overcome this obstacle, astronomers have developed a method that makes it possible to ensure the presence of a planet in a few months, even if it takes 10 years to circle its star. […]

  • Supersharp images from new VLT adaptive optics
    on July 18, 2018 at 12:22 pm

    ESO's Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography -- and has captured remarkably sharp test images of the planet Neptune and other objects. The MUSE instrument working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope. […]

  • A dozen new moons of Jupiter discovered, including one 'oddball'
    on July 17, 2018 at 2:12 pm

    Twelve new moons orbiting Jupiter have been found -- 11 'normal' outer moons, and one that they're calling an 'oddball.' Astronomers first spotted the moons in the spring of 2017 while they were looking for very distant solar system objects as part of the hunt for a possible massive planet far beyond Pluto. […]

  • Astronomers find a famous exoplanet's doppelganger
    on July 17, 2018 at 1:48 pm

    A new planet has been imaged, and it appears nearly identical to one of the best studied gas-giant planets. But this doppelganger differs in one very important way: Its origin. One object has long been known: the 13-Jupiter-mass planet beta Pictoris b, one of the first planets discovered by direct imaging, back in 2009. The new object, dubbed 2MASS 0249 c, has the same mass, brightness, and spectrum as beta Pictoris b. […]

  • Disruption tolerant networking to demonstrate Internet in space
    on July 16, 2018 at 3:45 pm

    The interplanetary Internet may soon become a reality. NASA is about to demonstrate Delay/Disruption Tolerant Networking, or DTN -- a technology that sends information through space and ground networks to its destination. […]

  • How might dark matter interact with ordinary matter?
    on July 13, 2018 at 1:35 pm

    Scientists have imposed conditions on how dark matter may interact with ordinary matter. In the search for direct detection of dark matter, the experimental focus has been on WIMPs, or weakly interacting massive particles, the hypothetical particles thought to make up dark matter. But the research team invokes a different theory to challenge the WIMP paradigm: the self-interacting dark matter model, or SIDM. […]

  • VERITAS supplies critical piece to neutrino discovery puzzle
    on July 12, 2018 at 3:45 pm

    The VERITAS array has confirmed the detection of gamma rays from the vicinity of a supermassive black hole. While these detections are relatively common for VERITAS, this black hole is potentially the first known astrophysical source of high-energy cosmic neutrinos, a type of ghostly subatomic particle. […]

  • Breakthrough in the search for cosmic particle accelerators
    on July 12, 2018 at 3:45 pm

    In a global observation campaign, scientist have for the first time located a source of high-energy cosmic neutrinos, ghostly elementary particles that travel billions of light years through the universe, flying unaffected through stars, planets and entire galaxies. […]

  • Centenary of cosmological constant lambda
    on July 11, 2018 at 2:57 pm

    Physicists are now celebrating the 100th anniversary of the cosmological constant. On this occasion, two recent articles highlight its role in modern physics and cosmology. Before becoming widely accepted, the cosmological constant had to undergo many discussions about its necessity, its value and its physical essence. Today, there are still unresolved problems in understanding the deep physical nature of the phenomena associated with the cosmological constant. […]

  • Colorful celestial landscape

    New observations show the star cluster RCW 38 in all its glory. This image was taken during testing of the HAWK-I camera with the GRAAL adaptive optics system. It shows RCW 38 and its surrounding clouds of brightly glowing gas in exquisite detail, with dark tendrils of dust threading through the bright core of this young gathering of stars. […]

  • Rocky planet neighbor looks familiar, but is not Earth's twin
    on July 10, 2018 at 4:28 pm

    Last autumn, the world was excited by the discovery of an exoplanet called Ross 128 b, which is just 11 light years away from Earth. New work has for the first time determined detailed chemical abundances of the planet's host star, Ross 128. […]

  • Plasma-spewing quasar shines light on universe's youth, early galaxy formation
    on July 9, 2018 at 2:11 pm

    Astronomers found a quasar with the brightest radio emission ever observed in the early universe, due to it spewing out a jet of extremely fast-moving material. Scientists have revealed in unprecedented detail the jet shooting out of a quasar that formed within the universe's first billion years of existence. […]

  • The Gaia Sausage: The major collision that changed the Milky Way galaxy
    on July 4, 2018 at 3:20 pm

    Astronomers have discovered an ancient and dramatic head-on collision between the Milky Way and a smaller object, dubbed the 'Sausage' galaxy. The cosmic crash was a defining event in the early history of the Milky Way and reshaped the structure of our galaxy, fashioning both its inner bulge and its outer halo, the astronomers report in a series of new papers. […]

  • Milky Way type dust particles discovered in a galaxy 11 billion light years from Earth
    on July 3, 2018 at 2:59 pm

    An international research team has found the same type of interstellar dust that we know from the Milky Way in a distant galaxy 11 billion light years from Earth. This type of dust has been found to be rare in other galaxies and the new discovery plays an important role in understanding what it takes for this particular type of interstellar dust to be formed. […]

  • First confirmed image of newborn planet caught with ESO's VLT
    on July 2, 2018 at 1:40 pm

    SPHERE, a planet-hunting instrument on ESO's Very Large Telescope, has captured the first confirmed image of a planet caught in the act of forming in the dusty disc surrounding a young star. The young planet is carving a path through the primordial disc of gas and dust around the very young star PDS 70. The data suggest that the planet's atmosphere is cloudy. […]

  • Astronomers observe the magnetic field of the remains of supernova 1987A
    on June 29, 2018 at 2:26 pm

    For the first time, astronomers have directly observed the magnetism in one of astronomy's most studied objects: the remains of Supernova 1987A (SN 1987A), a dying star that appeared in our skies over thirty years ago. In addition to being an impressive observational achievement, the detection provides insight into the early stages of the evolution of supernova remnants and the cosmic magnetism within them. […]
