  • A Cosmic Pretzel
    Astronomers using ALMA have obtained an extremely high-resolution image showing two disks in which young stars are growing, fed by a complex pretzel-shaped network of filaments of gas and dust. Observing this remarkable phenomenon sheds new light on the earliest phases of the lives of stars and helps astronomers determine the conditions in which binary stars are born.

  • Enigmatic radio burst illuminates a galaxy’s tranquil ​halo
    Astronomers using ESO’s Very Large Telescope have for the first time observed that a fast radio burst passed through a galactic halo. Lasting less than a millisecond, this enigmatic blast of cosmic radio waves came through almost undisturbed, suggesting that the halo has surprisingly low density and weak magnetic field. This new technique could be used to explore the elusive halos of other galaxies.

  • VISTA unveils a new image of the Large Magellanic Cloud
    ESO’s VISTA telescope reveals a remarkable image of the Large Magellanic Cloud, one of our nearest galactic neighbours. VISTA has been surveying this galaxy and its sibling the Small Magellanic Cloud, as well as their surroundings, in unprecedented detail. This survey allows astronomers to observe a large number of stars, opening up new opportunities to study stellar evolution, galactic dynamics, and variable stars.

  • Anatomy of a Cosmic Seagull
    Colourful and wispy, this intriguing collection of objects is known as the Seagull Nebula, named for its resemblance to a gull in flight. Made up of dust, hydrogen, helium and traces of heavier elements, this region is the hot and energetic birthplace of new stars. The remarkable detail captured here by ESO’s VLT Survey Telescope (VST) reveals the individual astronomical objects that make up the celestial bird, as well as the finer features within them. The VST is one of the largest survey telescopes in the world observing the sky in visible light.

  • La Silla 50th Anniversary Culminates with Total Solar Eclipse
    On 2 July, the path of totality of a solar eclipse passed across ESO’s La Silla Observatory. This rare astronomical event falls in the fiftieth year of operation of ESO’s first observatory. Inaugurated in 1969, La Silla Observatory led Europe to the front line of astronomical research and continues to deliver remarkable science. 1000 visitors, including the President of the Republic of Chile, journeyed to the remote observatory to witness the unique conjunction.

  • Breakthrough Watch and the European Southern Observatory achieve “first light” on upgraded planet-finding instrument to search for Earth-like planets in nearest star system
    Newly-built planet-finding instrument installed on Very Large Telescope, Chile, begins 100-hour observation of nearby stars Alpha Centauri A and B, aiming to be first to directly image a habitable exoplanet

  • ESO contributes to protecting Earth from dangerous asteroids
    The unique capabilities of the SPHERE instrument on ESO’s Very Large Telescope have enabled it to obtain the sharpest images of a double asteroid as it flew by Earth on 25 May. While this double asteroid was not itself a threatening object, scientists used the opportunity to rehearse the response to a hazardous Near-Earth Object (NEO), proving that ESO’s front-line technology could be critical in planetary defence.

  • €17 million Fund Backs 170 Breakthrough Concepts in Imaging and Sensing
    ATTRACT, a Horizon 2020 research and innovation project funded by the European Union and backed by a consortium of 9 partners including ESO, has announced 170 breakthrough ideas which will each receive €100,000 to develop technologies that have the potential to change society. The selected proposals include projects which highlight the societal benefits of ESO's astronomical expertise.

  • Pinpointing Gaia to Map the Milky Way
    This image, a composite of several observations captured by ESO’s VLT Survey Telescope (VST), shows the ESA spacecraft Gaia as a faint trail of dots across the lower half of the star-filled field of view. These observations were taken as part of an ongoing collaborative effort to measure Gaia’s orbit and improve the accuracy of its unprecedented star map.

  • Astronomers Capture First Image of a Black Hole
    The Event Horizon Telescope (EHT) — a planet-scale array of eight ground-based radio telescopes forged through international collaboration — was designed to capture images of a black hole. Today, in coordinated press conferences across the globe, EHT researchers reveal that they have succeeded, unveiling the first direct visual evidence of a supermassive black hole and its shadow.
