METIS-Instrument des ELT besteht Design-Etappenziel
5. Juni 2020
METIS, der leistungsstarke Imager und Spektrograf für das Extremely Large Telescope (ELT) der ESO, hat im Hauptsitz der ESO in Garching seine vorläufige Designprüfung bestanden. METIS, kurz für „Mid-infrared ELT Imager and Spectrograph“, wird den riesigen Hauptspiegel des Teleskops voll nutzen, um eine große Bandbreite wissenschaftlicher Themen zu untersuchen – von Objekten in unserem Sonnensystem bis zu fernen aktiven Galaxien. METIS wird extrem gut geeignet sein, um den Lebenszyklus von Sternen zu erforschen, von jungen Sternen und planetenbildenden Scheiben bis zu älteren Sternen gegen Ende ihrer Lebenszeit.
Das ELT wird das größte optische, bis zum mittleren Infrarotbereich nutzbare Teleskop der Welt sein, wenn es gegen Mitte dieses Jahrzehnts in Betrieb geht. Mit seinem 39 Meter großen Hauptspiegel und den fortschrittlichen Systemen für adaptive Optik wird es die sechsfache Auflösung des James-Webb-Weltraumteleskops haben. METIS wird dieses bemerkenswerte Teleskop und seine adaptive Optik voll ausnutzen, um Strukturen und Zusammensetzung von Objekten mit revolutionärer Präzision zu untersuchen.
Unter anderem wird von METIS erwartet, dass es große Beiträge zu einem der dynamischsten und aufregendsten Bereiche der Astronomie sowohl für Wissenschaftler als auch für die Öffentlichkeit, den Exoplaneten, leisten wird. Das Instrument wird in der Lage sein, Temperatur, Wetter und jahreszeitliche Veränderungen in der Atmosphäre vieler riesiger Exoplaneten zu untersuchen. Außerdem hat METIS das Potenzial, direkt terrestrische Exoplaneten bei den nächsten Sternen zu entdecken und, in günstigen Fällen, die Zusammensetzung ihrer Atmosphäre zu erforschen.
Jetzt, da das Instrument seine vorläufige Designprüfung bestanden hat, wird das METIS Konsortium das Design im Detail weiterentwickeln, bevor der Bau des Instruments beginnt.
