First Giant Planet around White Dwarf Found Researchers using ESO’s Very Large Telescope have, for the first time, found evidence of a giant planet associated with a white dwarf star. The planet orbits the hot white dwarf, the remnant of a Sun-like star, at close range, causing its atmosphere to be stripped away and form […]
ESO Telescope Reveals What Could be the Smallest Dwarf Planet Yet in the Solar System Astronomers using ESO’s SPHERE instrument at the Very Large Telescope (VLT) have revealed that the asteroid Hygiea could be classified as a dwarf planet. The object is the fourth largest in the asteroid belt after Ceres, Vesta and Pallas. For […]
First identification of a heavy element born from neutron star collision For the first time, a freshly made heavy element, strontium, has been detected in space, in the aftermath of a merger of two neutron stars. This finding was observed by ESO’s X-shooter spectrograph on the Very Large Telescope (VLT) and is published today in […]
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 […]
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 […]
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 […]
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 […]
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 […]
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 News […]
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 […]
€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 […]
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 […]
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 […]
La Silla Observatory turns 50! Since its inauguration in 1969, ESO’s La Silla Observatory has been at the forefront of astronomy. Its suite of state-of-the-art instruments has allowed astronomers to make ground-breaking discoveries and paved the way for future generations of telescopes. Even after 50 years of observations, ESO’s telescopes at La Silla continue to […]
GRAVITY instrument breaks new ground in exoplanet imaging The GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex exoplanetary atmosphere with clouds of iron and silicates swirling in a planet-wide storm. The technique presents unique possibilities for characterising […]
A Cosmic Bat in Flight Hidden in one of the darkest corners of the Orion constellation, this Cosmic Bat is spreading its hazy wings through interstellar space two thousand light-years away. It is illuminated by the young stars nestled in its core — despite being shrouded by opaque clouds of dust, their bright rays still illuminate the […]
Bubbles of Brand New Stars This dazzling region of newly-forming stars in the Large Magellanic Cloud (LMC) was captured by the Multi Unit Spectroscopic Explorer instrument (MUSE) on ESO’s Very Large Telescope. The relatively small amount of dust in the LMC and MUSE’s acute vision allowed intricate details of the region to be picked out […]
A Fleeting Moment in Time The faint, ephemeral glow emanating from the planetary nebula ESO 577-24 persists for only a short time — around 10,000 years, a blink of an eye in astronomical terms. ESO’s Very Large Telescope captured this shell of glowing ionised gas — the last breath of the dying star whose simmering […]
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 […]
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 […]
