Nachtschwärmen

Blutmond und Mars rücken sich am 27. Juli imposant ins Sternenbild

Am 27. Juli kann man in Graz die längste totale Mondfinsternis in diesem Jahrhundert beobachten – die totale Verfinsterung wird über 100 Minuten lang andauern. Wenn der Mond um 20.30 Uhr aufgeht, wird er schon zu acht Prozent verfinstert sein. Von 21.30 bis 23.14 Uhr befindet sich der Trabant gänzlich im Schatten der Erde und ist als blutrote Scheibe zu sehen. Ab 00.19 Uhr strahlt er wieder voll.
„Die Umlaufbahn des Mondes um unseren Planeten ist elliptisch, daher bewegt er sich scheinbar langsamer, je weiter er von der Erde entfernt ist“, nennt Astrophysiker Arnold Hanslmeier den Grund für die außergewöhnlich lange Verfinsterung. Was das seltene Phänomen für begeisterte SternenguckerInnen noch interessanter macht: In derselben Nacht steht der Mars in erdnaher Opposition. „Das heißt, er steht der Sonne gegenüber und geht genau dann auf, wenn sie untergeht. Außerdem ist er ‚nur‘ 56 Millionen Kilometer von unserem Planeten entfernt, was lediglich alle 15 Jahre vorkommt“, beschreibt Hanslmeier. Dadurch ist der Mars auch für LaiInnen deutlich als hell-rötlicher Stern unter dem verfinsterten Mond zu beobachten.
Nachtschwärmer und Hobby-Astronominnen können am 27. Juli von 20 bis 24 Uhr ans Observatorium Lustbühel kommen und dort unter fachkundiger Anleitung die Himmelsphänomene verfolgen.

Learning better: Can science experiments in group settings help children with autism?

How can pupils with autism spectrum disorder (ASD) have positive learning experiences and improve their social skills? Researchers at the University of Graz are investigating how science experiments in group settings can contribute to this. Initial results from the project, which is funded by the Austrian Science Fund FWF, show that children react differently depending on the kind of neurodiversity, but that experimentation classes with the right setting definitely have potential. "Pupils with ASD can do more than is currently expected of them in many cases," says project leader Uwe Simon.

Sustainability Award 2024 for two projects of the University of Graz

How do major international conferences reduce their carbon footprint? And what can maths lessons contribute to education for sustainable development? Two questions that were answered at the University of Graz. The corresponding projects were awarded the Sustainability Award 2024 in silver on 26 November in Vienna. This award for Austria's universities and colleges is presented by the Ministry of Science and the Ministry of Climate Protection.

Bees under observation: University of Graz provides unprecedented insights into the hive

What is going on in the combs? How many eggs is the queen laying? How much honey is there? Autonomous robots and AI algorithms provide important data and high-resolution real-time images from inside a beehive. "As part of an international team, we have developed a game-changer technology for a new type of digitalised behavioural research," reports biologist Thomas Schmickl from the Artifical Life Lab at the University of Graz. The publication, which has just appeared as the cover story in the journal "Science Robotics", describes the wealth of information that can be obtained from this unique research facility.

Research for healthy aging: FWF funds Cluster of Excellence "MetAGE" with 18 million euros

Six researchers from the Field of Excellence "BioHealth" at the University of Graz, together with colleagues from the Medical Universities of Graz and Vienna, have acquired an FWF-funded "Cluster of Excellence". Now a newly formed center of excellence will be created under the leadership of the University of Graz. The aim is to gain a better understanding of healthy aging. The findings will flow directly into clinical research.
