UK researchers have just signed an agreement to lead one of the first instruments for what will become the World’s largest visible and infrared telescope, the European Extremely Large Telescope (E-ELT). The spectrograph, called HARMONI, will provide the European Southern Observatory’s telescope with a sensitivity that is up to hundreds of times better than any current telescope of its kind.
The Sculptor Dwarf Galaxy, pictured in this new image from ESO’s La Silla Observatory, is a close neighbour of the Milky Way. This galaxy is much smaller and older than ours, making it a valuable subject for studying both star and galaxy formation in the early universe. However, due to its faintness, studying this object is no easy task.
The first results have been released from a major new dark matter survey of the southern skies using ESO’s VLT Survey Telescope (VST) at the Paranal Observatory in Chile. The VST KiDS survey will allow astronomers to make precise measurements of dark matter, the structure of galaxy halos, and the evolution of galaxies and clusters.
Many galaxies blast huge, wide-angled flows of material outward from their centres, pushing to their outer edges enough dust and gas each year that otherwise would have formed more than a thousand stars the size of our Sun. A team led by University of Maryland scientists has found the driving force behind these massive molecular outflows.
