The Milky Way dazzles above the La Silla Observatory in Chile, framed by the now-deactivated Swedish-European Southern Observatory submillimetre telescope on the left and ESO’s 3.6-metre (11.8-foot) optical telescope on the right. But the Milky Way is the star of the show with the reddish Gum Nebula at the peak of the arc and the Large and Small Magellanic clouds visible just above and to the right of the dish antenna. Brilliant Jupiter shines above and to the left of the 3.6-metre telescope’s dome.
ALMA detects most distant signs of oxygen in the universe
An international team of astronomers has used the Atacama Large Millimetre/submillimetre Array (ALMA) to detect glowing oxygen in a distant galaxy seen just 700 million years after the Big Bang. This is the most distant galaxy in which oxygen has ever been unambiguously detected, and it is most likely being ionised by powerful radiation from young giant stars.
Atacama Pathfinder Experiment (APEX) starts its second decade
The Atacama Pathfinder Experiment (APEX) is a 12-metre radio telescope for observations at submillimetre wavelengths, operating 5,100 metres above sea level in the Atacama Desert. On 25-26 January, the project’s 10th anniversary was celebrated at the APEX base station in Sequitor, San Pedro de Atacama. A number of special guests were present at the occasion.
Spectacular VLT images of Jupiter presented before Juno’s arrival
In preparation for the imminent arrival of NASA’s Juno spacecraft, astronomers have used ESO’s Very Large Telescope to obtain spectacular new infrared images of Jupiter as part of a campaign to create high-resolution maps of the giant planet. These observations will help astronomers to better understand the gas giant ahead of Juno’s close encounter next month.
