This striking view of the central parts of the Milky Way was obtained with the VISTA survey telescope at ESO’s Paranal Observatory in Chile. This huge picture is 108 200 by 81 500 pixels and contains nearly nine billion pixels. It was created by combining thousands of individual images from VISTA, taken through three different infrared filters, into a single monumental mosaic. These data form part
Subsequent very careful study of this data by independent groups has strongly suggested that the planet around Alpha Centauri B reported here probably does not exist. The signal appears to be a very subtle artifact of the way the data was collected and analysed. Further details are given in the paper by Rajpaul et al. (https://arxiv.org/abs/1510.05598). Note added 17 January 2017. Press Release Pl

The darkest sky ? Milky Way all around the horizon line and Gegenschein. I was wondering what conditions should be met to have the "darkest" sky ... Well, obviously there should be no Moon light. The Milky Way and Zodiacal light should not be visible neither , or kept to a minimum, and the image should be taken at a place with no light pollution. If these are correct criteriae, the following pictu
This is the first image of Sgr A*, the supermassive black hole at the centre of our galaxy. It’s the first direct visual evidence of the presence of this black hole. It was captured by the Event Horizon Telescope (EHT), an array which linked together eight existing radio observatories across the planet to form a single “Earth-sized” virtual telescope. The telescope is named after the event horizon
Press Release Richest Planetary System Discovered Up to seven planets orbiting a Sun-like star 24 August 2010 Astronomers using ESO’s world-leading HARPS instrument have discovered a planetary system containing at least five planets, orbiting the Sun-like star HD 10180. The researchers also have tantalising evidence that two other planets may be present, one of which would have the lowest mass eve
Press Release Stars Just Got Bigger A 300 Solar Mass Star Uncovered 21 July 2010 Using a combination of instruments on ESO’s Very Large Telescope, astronomers have discovered the most massive stars to date, one weighing at birth more than 300 times the mass of the Sun, or twice as much as the currently accepted limit of 150 solar masses. The existence of these monsters — millions of times more lum
This magnificent 360-degree panoramic image, covering the entire southern and northern celestial sphere, reveals the cosmic landscape that surrounds our tiny blue planet. This gorgeous starscape serves as the first of three extremely high-resolution images featured in the GigaGalaxy Zoom project, launched by ESO within the framework of the International Year of Astronomy 2009 (IYA2009). The plane
The three images of ESO’s GigaGalaxy Zoom project showing the sky at different levels: from the view seen by the unaided eye to one seen through an amateur telescope, with a final zoom in onto the Lagoon Nebula as seen through a professional telescope. Credit:
ESO telescope captures the most detailed infrared map ever of our Milky Way Astronomers have published a gigantic infrared map of the Milky Way containing more than 1.5 billion objects ― the most detailed one ever made. Using the European Southern Observatory’s VISTA telescope, the team monitored the central regions of our Galaxy over more than 13 years. At 500 terabytes of data, this is the large
The Portal To The Universe was one of the Cornerstone projects of the International Year of Astronomy 2009 (IYA2009) and operated from 2009 to 2021. For over a decade it ran on Web 2.0 technologies, serving as an index and aggregator of online astronomy content. This Mini Site is not available for sale. Credit:
ESO 22/07 - Science Release 25 April 2007 For Immediate Release Astronomers Find First Earth-like Planet in Habitable Zone The Dwarf Carried Other Worlds Too! Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope, a team of Swiss, French an
Groundbreaking survey reveals secrets of planet birth around dozens of stars In a series of studies, a team of astronomers has shed new light on the fascinating and complex process of planet formation. The stunning images, captured using the European Southern Observatory's Very Large Telescope (ESO’s VLT) in Chile, represent one of the largest ever surveys of planet-forming discs. The research bri
