Die SommerKinderUniGraz machte unter anderem bei Astrophysiker Hanslmeier Station

Während die "großen" in den Ferien sind, haben die jungen Studierenden in den vergangenen vier Wochen (11. Juli bis 5. August 2016) den Campus und die Hörsäle erobert. Die SommerKinderUniGraz ging auch an der Uni Graz über die Bühne. Bei wissenschaftlichen Kursen konnten die ForscherInnen im Alter zwischen acht und vierzehn Jahren vormittags das Gehirn, nachmittags beim Sportprogramm des USI die Muskeln trainieren.

Bei einem Workshop ermöglichte Astrophysiker Arnold Hanslmeier den jungen Studierenden einen fachkundigen Blick zu den Sternen. Auf dem astronomischen Turm des Physik-Institutes der Karl-Franzens-Universität konnten die Kinder den Himmel über ihren klugen Köpfen besser kennenlernen.

„Nur durch einen Blick auf einen Himmelskörper können Astronominnen und Astronomen viele wichtige Informationen ablesen“, erklärte Arnold Hanslmeier. „Die Farbe eines Sterns zeigt uns beispielsweise, wie hoch oder wie tief die Oberflächentemperatur dieses Sterns ist. Kühlere Sterne scheinen rot, während heißere Sterne hauptsächlich blau oder weiß auf uns wirken.“
Der Forscher erklärte auch die Dimensionen im All sehr anschaulich: „Nehmen wir einmal theoretisch an, wir hätten eine Rakete, welche die Entfernung zwischen der Erde und dem Mond in nur einer einzigen Stunde zurücklegen könnte.“ Und wenn die Reise weiter geht: „Dieselbe Rakete würde 17 Tage brauchen, um von der Erde zur Sonne zu fliegen. Und zum Stern Proxima Centauri, der unserer Sonne am nächsten von allen Sternen liegt, bräuchte diese Rakete 13.600 Jahre.“

Crystal-clear: AI method revolutionises solar observation

The Sun makes life on Earth possible. However, its magnetic fields can also cause massive disruption. This makes it all the more important to gain a better understanding of the processes taking place on our nearest star. A research team from the University of Graz and the High Altitude Observatory in Boulder (USA) has succeeded in doing just that. The astrophysicists have developed an AI-supported method that makes even the smallest structures on the Sun visible. The scientists are convinced that this will bring about a lasting change in solar observation and that the new method can be used for the planned European Solar Telescope.

Long Night of Research: How many languages are there in the world?

From a linguistic perspective, there are worlds of difference between Bern, Berlin and Vienna. A dialect impersonator will demonstrate live just how varied German can sound. How many languages are there in the world? What are their distinctive features? Which of these are spoken in Austria? These and other questions will be answered during the Long Night of Research at the University of Graz: on Friday, 24 April 2025, from 5 pm to 11 pm, in the University Library. Visitors can immerse themselves in the diversity of languages without travelling far by taking part in a quiz at the station.
