  • Free Open Source Materials from the ESO Supernova Planetarium & Visitor Centre
    Since it opened in April 2018, the ESO Supernova Planetarium & Visitor Centre has shared the wonders of the Universe with more than 55 000 visitors and captured the attention of audiences from around the globe. Now, the ESO Supernova’s extensive library of high-resolution images, stunning videos, educational texts and planetarium resources, as well as a digital version of its state-of-the-art astronomical exhibition, have been made freely available online.

  • ESO to Host Cherenkov Telescope Array-South at Paranal
    ESO’s Director General and the Managing Director of the Cherenkov Telescope Array (CTA) Observatory have signed the agreement needed for CTA’s southern hemisphere array to be hosted near ESO’s Paranal Observatory in Chile. In addition, the Chilean Government and ESO have signed the agreement enabling ESO to host this new telescope within ESO’s Paranal Observatory site. This will allow the world's most ambitious gamma-ray observatory to access not only Chile’s pristine observing conditions, but also ESO’s state-of-the-art infrastructure, expertise, and facilities. ESO will operate the facility on behalf of the CTA Observatory and its Members.

  • Dancing with the Enemy
    While testing a new subsystem on the SPHERE planet-hunting instrument on ESO’s Very Large Telescope, astronomers were able to capture dramatic details of the turbulent stellar relationship in the binary star R Aquarii with unprecedented clarity — even compared to observations from Hubble.

  • First Light for SPECULOOS
    The SPECULOOS project has made its first observations at the European Southern Observatory’s Paranal Observatory in northern Chile. SPECULOOS will focus on detecting Earth-sized planets orbiting nearby ultra-cool stars and brown dwarfs.

  • Cosmic Serpent
    The VISIR instrument on ESO’s Very Large Telescope has captured this stunning image of a newly discovered massive triple star system. Nicknamed Apep after an ancient Egyptian deity, this may be the first ever gamma-ray burst progenitor found.

  • Super-Earth Orbiting Barnard’s Star
    The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth — a so-called super-Earth. One of the largest observing campaigns to date using data from a world-wide array of telescopes, including ESO’s planet-hunting HARPS instrument, have revealed this frozen, dimly lit world. The newly discovered planet is the second-closest known exoplanet to the Earth. Barnard’s star is the fastest moving star in the night sky.

  • ALMA and MUSE Detect Galactic Fountain
    Observations by ALMA and data from the MUSE spectrograph on ESO’s VLT have revealed a colossal fountain of molecular gas powered by a black hole in the brightest galaxy of the Abell 2597 cluster — the full galactic cycle of inflow and outflow powering this vast cosmic fountain has never before been observed in one system.

  • Most Detailed Observations of Material Orbiting close to a Black Hole
    ESO’s exquisitely sensitive GRAVITY instrument has added further evidence to the long-standing assumption that a supermassive black hole lurks in the centre of the Milky Way. New observations show clumps of gas swirling around at about 30% of the speed of light on a circular orbit just outside its event horizon — the first time material has been observed orbiting close to the point of no return, and the most detailed observations yet of material orbiting this close to a black hole.

  • The Pirate of the Southern Skies
    FORS2, an instrument mounted on ESO’s Very Large Telescope, has observed the active star-forming region NGC 2467 — sometimes referred to as the Skull and Crossbones Nebula. The image was captured as part of the ESO Cosmic Gems Programme, which makes use of the rare occasions when observing conditions are not suitable for gathering scientific data. Instead of sitting idle, the ESO Cosmic Gems Programme allows ESO’s telescopes to be used to capture visually stunning images of the southern skies.

  • Largest Galaxy Proto-Supercluster Found
    An international team of astronomers using the VIMOS instrument of ESO’s Very Large Telescope have uncovered a titanic structure in the early Universe. This galaxy proto-supercluster — which they nickname Hyperion — was unveiled by new measurements and a complex examination of archive data. This is the largest and most massive structure yet found at such a remote time and distance — merely 2 billion years after the Big Bang.
