Asteroid nach Astrophysiker Arnold Hanslmeier benannt

Als Wissenschaftler in den Himmel gehoben werden. Buchstäblich. Das ist Astrophysiker Arnold Hanslmeier gelungen. Denn seit kurzem trägt ein Asteroid den Namen des Forschers. Asteroid Hanslmeier wurde 2001 mit der Nummer 182674 =2001 UB 225 am Apache Point Observatory in New Mexico/USA entdeckt. Das Objekt im All gehört zum Hauptgürtel der Asteroiden. „Er kann sich der Erde bis auf 225 Millionen Kilometer nähern und läuft in 4,4 Jahren einmal um die Sonne“, beschreibt der Namenspatron.
Für die Benennung von Asteroiden sind folgende Kriterien Voraussetzung: außergewöhnliche wissenschaftliche Leistungen sowie außergewöhnliche Beiträge für die Wissenschaft und Öffentlichkeitsarbeit.

Und noch einen weiteren „Stern“ auf dem Karrierepfad der Wissenschaft kann Arnold Hanslmeier verbuchen. Das Standardwerk „Einführung in Astronomie und Astrophysik“, erschienen im Springer Verlag, ist bereits in der vierten Auflage erschienen. Aufgrund der großen Nachfrage wurde das Buch nun auch in englischer Sprache als „Introduction to Astronomy and Astrophysics“ herausgegeben. Die 700 Seiten enthalten viele spektakuläre Abbildungen, darunter auch einige, die mit dem neuen James Webb-Teleskop gemacht wurden.

Austria’s emissions rose in 2025: University of Graz researchers analyse the causes

The Environment Agency Austria has today published the figures for the country’s greenhouse gas emissions in 2025. While emissions fell sharply year on year from 2022 to 2024, they rose again by just under 0.7 per cent in 2025. Researchers at the University of Graz have analysed how much of this increase was due to structural changes in the economy and how much was attributable to external factors over which there is little control. “In 2025, the colder winter compared with 2024 increased emissions by 0.81 per cent, while the weak economy reduced them by 0.38 per cent. If we factor out these influences, we find an underlying increase of 0.26 per cent compared with the previous year,” reports economist Karl Steininger. “This clearly means that Austria is not on track to meet its climate targets, which require a substantial reduction in emissions by 2030.”

Electrifying: Researchers film the first moments on the way from light to electricity

Physicists at the University of Graz (Austria), in collaboration with colleagues from Marburg University and Forschungszentrum Jülich (Germany), have achieved a scientific breakthrough. For the first time, the generation of electrical energy from light has been filmed and described theoretically. This work is of far-reaching significance, not least for optimising sustainable energy production from photovoltaics. This is because it provides fundamental building blocks for understanding the physical processes that take place, for example, in organic solar cells. The paper was published in the journal Physical Review X, one of the world’s most prestigious physics journals.

How can we teach using YouTube and AI? The University of Graz is strengthening media education in schools

A journey through the blood vessels using VR headsets brings biology lessons to life. An interactive quiz brings physics to life. The YouTube video explains the First World War. Whilst mobile phones are increasingly being banned from the classroom, social media platforms, apps and AI are playing an ever-greater role in knowledge transfer at school. But how can teaching with media be made even more effective? What are the challenges in media-based teaching? At the University of Graz, researchers are discussing these issues at a conference being held in Austria for the first time.
