Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very Large Array (VLA) made a rare detection of a likely stellar flyby event in the Z Canis Majoris (Z CMa) star system. An intruder—not bound to the system—object came in close proximity to and interacted with the environment surrounding the binary protostar, causing the formation of chaotic, stretched-out streams of dust and gas in the disk surrounding it. While such intruder-based flyby (...)

The European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI) has obtained the deepest and sharpest images to date of the region around the supermassive black hole at the centre of our galaxy. The new images zoom in 20 times more than what was possible before the VLTI and have helped astronomers find a never-before-seen star close to the black hole. By tracking the orbits of stars at the centre of our Milky Way, the team has made the most precise measurement yet of the (...)

The European Southern Observatory’s Very Large Telescope (ESO’s VLT) has captured an image of a planet orbiting b Centauri, a two-star system that can be seen with the naked eye. This is the hottest and most massive planet-hosting star system found to date, and the planet was spotted orbiting it at 100 times the distance Jupiter orbits the Sun. Some astronomers believed planets could not exist around stars this massive and this hot — until now. "Finding a planet around b Centauri was very (...)

Ultra-light and super-fast
As far as extrasolar planets go, ‘GJ 367 b’ is a featherweight. With half the mass of Earth, the newly discovered planet is one of the lightest among the nearly 5000 exoplanets known today. It takes the extrasolar planet approximately eight hours to orbit its parent star. With a diameter of just over 9000 kilometres, GJ 367 b is slightly larger than Mars. The planetary system is located just under 31 light years from Earth and is thus ideal for further (...)

Using the Atacama Large Millimetre/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have unambiguously detected the presence of a disc around a planet outside our Solar System for the first time. The observations will shed new light on how moons and planets form in young stellar systems.
This image, taken with the Atacama Large Millimeter/submillimeter Array ([ALMA->https://www.eso.org/public/teles-instr/alma), in which ESO is a (...)

Concerto, a state-of-the-art spectrometer designed by a consortium of French laboratories, including the Institut de Planétologie et d’Astrophysique de Grenoble, led by the Laboratoire d’Astrophysique de Marseille, is on its way to the Atacama Desert in Chile. It will be installed, from April 6th, at an altitude of more than 5000 meters on the Apex telescope. Unique in its kind, Concerto should allow scientists to better understand one of the crucial periods of the formation of the Universe: (...)

Snow line observations reveal the unsteady history of a very young protostar It is a story many parents are hoping for: Imagine there’s a very young kid that seems like a real low-performer, but then it turns out that secretly it has its very powerful moments — such that the odds are pretty good it will become a real star, eventually. In fact, this is very much what an international team of astronomers found when they examined the very young protostar IRAM 04191+1522 (IRAM 04191, in short). (...)

In 2015 the New Horizons spacecraft discovered spectacular mountains on Pluto covered by bright deposits, strikingly resembling snow-capped mountain chains seen on Earth. Such a landscape had never been observed elsewhere in the Solar System. Could Pluto’s atmosphere behave like Earth’s?

CNRS researchers at the Observatoire de Paris – PSL, Université Grenoble Alpes, Aix-Marseille Université, Université de Paris, and Université de Lille, together with their international partners, have for the first time detected the light emitted by the exoplanet β Pictoris c, initially discovered thanks to the tiny variations in the velocity of the star β Pictoris that it causes. A very accurate estimate of its position was used to point the GRAVITY interferometer at the exoplanet, simultaneously (...)
