  • 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. […]

  • 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. […]

  • 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. […]

  • Even phenomenally dense neutron stars fall like a feather
    on July 4, 2018 at 5:53 pm

    Astronomers have given one of Einstein's predictions on gravity its most stringent test yet. By precisely tracking the meanderings of three stars in a single system -- two white dwarf stars and one ultra-dense neutron star -- the researchers determined that even phenomenally compact neutron stars 'fall' in the same manner as their less-dense counterparts, an aspect of nature called the 'Strong Equivalence Principle.' […]

  • Most of Earth's meteorites came from five or six ancient planets
    on July 2, 2018 at 3:11 pm

    A study found at least 85 percent of 200,000 asteroids in the inner asteroid belt -- the main source of Earth's meteorites -- originate from five or six ancient minor planets. […]

  • A galactic test will clarify the existence of dark matter
    on June 25, 2018 at 11:27 pm

    Researchers used sophisticated computer simulations to devise a test that could answer a burning question in astrophysics: is there really dark matter? Or does Newton's gravitational law need to be modified? The new study shows that the answer is hidden in the motion of the stars within small satellite galaxies swirling around the Milky Way. […]

    Astronomers have made the most precise test of gravity outside our own solar system. By combining data taken with NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope, the researchers show that gravity in this galaxy behaves as predicted by Albert Einstein's general theory of relativity, confirming the theory's validity on galactic scales. […]

  • 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. […]

  • Dark inflation opens up a gravitational window onto the first moments after the Big Bang
    on June 7, 2018 at 2:09 pm

    Dark matter and dark energy may have driven inflation, the exponential expansion of the Universe moments after the Big Bang. A new cosmological model proposed by physicists, which takes dark inflation into account, is the first to outline a precise chronology of the main events during the early history of our Universe. The model makes a spectacular prediction: that it should be possible to detect gravitational waves that were formed just fractions of a second after the creation of spacetime. […]

  • How do you weigh a galaxy? Especially the one you're in?
    on June 6, 2018 at 9:38 pm

    Pinning down the mass of a galaxy may seem like an esoteric undertaking, but scientists think it holds the key to unraveling the nature of the elusive, yet-to-be-seen dark matter, and the fabric of our cosmos. A new technique promises more reliable estimates of the masses of galaxies. […]

  • Data discrepancies may affect understanding of the universe
    on June 5, 2018 at 9:24 pm

    One of the unsolved mysteries in modern science is why the expansion of the universe appears to be accelerating. As astrophysicists look for answers in the mountains of data gathered from astronomical observations, they are finding that inconsistencies in that data might ultimately lead to the truth. […]
