In this new image of the nebula Messier 78, young stars cast a bluish pall over their surroundings, while red fledgling stars peer out from their cocoons of cosmic dust. ESO’s Visible and Infrared Survey Telescope for Astronomy (VISTA) sees near-infrared light, which passes right through dust, permitting astronomers to probe deep into the heart of the stellar environment.
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.
Nearby dwarf galaxy Wolf—Lundmark—Melotte (WLM) poses an intriguing mystery: How is it able to form brilliant star clusters without the dusty, gas-rich environments found in larger galaxies? The answer, astronomers believe, lies in densely packed and previously unrecognised nuggets of star-forming material sprinkled throughout the galaxy.
