An international team of astronomers have used the Very Large Telescope Interferometer to image the Eta Carinae star system in the greatest detail ever achieved. They found new and unexpected structures within the binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding.
A spectacular new image of the Milky Way has been released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the galactic plane visible from the Southern Hemisphere for the first time at submillimetre wavelengths — between infrared light and radio waves.
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.
