height="264" style="border: 0px;"/></a></p> <div class="row"> <div class="col-md-8"> <p>The 4-metre Multi-Object Spectrograph Telescope, or 4MOST, is a second-generation instrument built for ESO’s 4.1-metre <a href="/web/20170624022751/http://www.eso.org/public/teles-instr/surveytelescopes/vista/">Visible and Infrared Survey Telescope for Astronomy</a> (VISTA) telescope based at the Paranal Observatory in northern Chile. 4MOST will occupy the <a href="/web/20170624022751/http://www.eso.org/public/teles-instr/surveytelescopes/vista/camera/">VISTA Infrared Camera</a> (VIRCAM) position which has conducted numerous surveys in the near-infrared since 2008.</p> <p><span>The new instrument will provide VISTA with the ability to perform large spectroscopic surveys, capturing the <a href="/web/20170624022751/http://www.eso.org/public/teles-instr/technology/spectroscopy/">spectra</a> of 2400 objects simultaneously. 4MOST will go well beyond the abilities of VIRCAM, allowing higher-resolution spectroscopic observations over a wider field of view, an area on the sky equivalent to 20 full Moons</span>.</p> <p>According to the team behind the design and construction of 4MOST, the instrument will provide ESO and the community with a world-class optical spectroscopic survey facility that will make major contributions to many of the science areas laid out in the <a href="/web/20170624022751/http://www.eso.org/sci/publications/messenger/archive/no.130-dec07/messenger-no130-2-4.pdf">ASTRONET</a>.</p> <p><em></em>In particular, 4MOST will execute nine key astronomical surveys in the first 5 years of operation. Four of them will focus on Galactic Science Surveys to complement the work of the <a href="https://web.archive.org/web/20170624022751/http://sci.esa.int/gaia/" target="_blank">Gaia</a> spacecraft. The main goal of this mission is “<em>to make the largest, most precise three-dimensional map of our Galaxy (the Milky Way)</em>”, and 4MOST will contribute to studies of the stellar halo and the bulge of the Milky Way.</p> <p>There will also be four <a href="https://web.archive.org/web/20170624022751/https://en.wikipedia.org/wiki/Extragalactic_astronomy" target="_blank">Extragalactic</a> Science Surveys: 4MOST will survey Active Galactic Nuclei  and galaxy clusters, and study the evolution of galaxies and the Dark Universe (Dark Energy, Dark Matter &amp;
