Beautiful nebula, violent history: clash of stars solves stellar mystery

When astronomers looked at a stellar pair at the heart of a stunning cloud of gas and dust, they were in for a surprise. Star pairs are typically very similar, like twins, but in HD 148937, one star appears younger and, unlike the other, is magnetic. New data from the European Southern Observatory (ESO) suggest there were originally three stars in the system, until two of them clashed and merged. This violent event created the surrounding cloud and forever altered the system’s fate. This image, taken with the VLT Survey Telescope hosted at ESO’s Paranal Observatory, shows the beautiful nebula NGC 6164/6165, also known as the Dragon’s Egg. The nebula is a cloud of gas and dust surrounding a pair of stars called HD 148937. Credit: ESO/VPHAS+ team. Acknowledgement: CASU “When doing ba...

First segments of the world's largest telescope mirror shipped to Chile The construction of the European Southern Observatory’s Extremely Large Telescope (ESO's ELT) has reached an important milestone with the delivery to ESO and shipment to Chile of the first 18 segments of the telescope’s main mirror (M1). Once they arrive in Chile, the segments will be transported to the ELT Technical Facility, at ESO’s Paranal Observatory in the country’s Atacama Desert, where they will be coated in preparation for their future installation on the telescope main structure. Unable to be physically made in one piece, M1 will consist of 798 individual segments arranged in a large hexagonal pattern, with an additional 133 being produced to facilitate the recoating of segments. Primary mirror, M1, se...

ESO’s ground based ELT is located atop Cerro Armazones in Chile’s Atacama Desert The European Southern Observatory’s Extremely Large Telescope (ESO’s ELT) is a revolutionary ground-based telescope that will have a 39-metre main mirror and will be the largest telescope in the world for visible and infrared light: the world’s biggest eye on the sky. Construction of this technically complex project is advancing at a good pace, with the ELT now surpassing the 50% complete milestone. This image, taken in late June 2023, shows a webcam image of the construction site of ESO’s Extremely Large Telescope at Cerro Armazones, in Chile's Atacama Desert. The starry background is dominated by the core of the Milky Way, our home galaxy, and the Large and Small Magellanic clouds, two dwarf galaxies ...

For the past 60 years the European Southern Observatory (ESO) has been enabling scientists worldwide to discover the secrets of the Universe. It mark this milestone by bringing a spectacular new image of a star factory, the Cone Nebula, taken with ESO’s Very Large Telescope (VLT). On 5 October 1962 five countries signed the convention to create ESO. Now, six decades later and supported by 16 Member States and strategic partners, ESO brings together scientists and engineers from across the globe to develop and operate advanced ground-based observatories in Chile that enable breakthrough astronomical discoveries. On the occasion of ESO’s 60th anniversary it is releasing this remarkable new image of the Cone Nebula, captured earlier this year with one of ESO’s telescopes and sel...
