Quantum entanglement defies weightlessness
The ÖAW and TU Vienna were able to show during a parabolic flight: A change in gravity has no influence on quantum experiments . A team from the Austrian Academy of Sciences and the Vienna University of Technology was able to prove this during a flight with the European Space Agency: Quantum entanglement also works when the strength of gravity changes.

Research Team Monitors Critical Infrastructure Using Navigation Satellites
Researchers at TU Graz have developed a new measuring system that can statically and dynamically monitor the condition of buildings using just a few antennas. From the outside, the Kölnbrein water dam, operated by Verbund in Carinthia, which is Austria's highest dam, and the DC Tower in Vienna, Austria's tallest building, do not have much in common, but for a research group around Caroline Schönberger and Werner Lienhart from the Institute of Engineering Geodesy and Measurement Systems at Graz University of Technology (TU Graz), they are equally interesting from a scientific point of view.

2023: A Year of Research Successes at TU Graz
At Graz University of Technology (TU Graz) in 2023, important discoveries were made, new insights gained and exciting information gleaned. An end-of-year review. TU Graz in Space In 2013, the small satellite TUGSAT-1 was Austria's first satellite in space. It was built at TU Graz and has been observing the earth from low earth orbit ever since.

Unlocking Neutron Star Rotation Anomalies
A collaboration between quantum physicists and astrophysicists, led by Francesca Ferlaino and Massimo Mannarelli, has achieved a significant breakthrough in understanding neutron star glitches. They were able to numerically simulate this enigmatic cosmic phenomenon with ultracold dipolar atoms. This research establishes a strong link between quantum mechanics and astrophysics and paves the way for quantum simulation of stellar objects from Earth.

When baby stars fledge
New method of age determination provides unexpected insights into the formation and drifting apart of young stars A team of astrophysicists led by Núria Miret-Roig from the University of Vienna found that two methods for determining the age of stars measure different things: Isochronous measurement thereby determines the birth date of stars, while dynamical tracking provides information on when stars "leave their nest", about 5.5 million years later in the star clusters studied.

Astronomers can look 50 times deeper into the atmosphere of this exoplanet than is possible with Jupiter A team of European astronomers, with the help of researchers from the University of Vienna, has studied the atmosphere of the nearby exoplanet WASP-107b using the James Webb Space Telescope. An exoplanet is a planet orbiting a star other than our sun.

Statistics of the invisible
In order to obtain information about dark matter and dark energy from the huge amounts of data to be generated by the new ESA probe Euclid, Innsbruck astrophysicist Laila Linke and her team are using novel statistical methods. As soon as Euclid sends its first data to Earth, the researchers intend to have a tool ready to gain new Astronomical measurements revealed that an unknown world lies hidden among all the pretty stars, nebulae and galaxies.

Water discovered in a zone where rocky planets usually form
Water detected by JWST in a planet-forming disk provides insight into the life-friendliness of Earth-like planets. The international MINDS research group has discovered water in the inner region of a disk of gas and dust around a young star with the James Webb Space Telescope. Usually, Earth-like planets form in this zone.

Starting signal for the exploration of the invisible universe
Researchers at the University of Innsbruck are working intensively on preparations for the Euclid mission of the European Space Agency ESA. The space telescope will be launched on July 1 and is expected to produce the largest 3D map of the universe to date. Scientists hope to learn more about the hitherto unexplored dark matter and dark energy of the universe.

Curved spacetime in a quantum simulator
New techniques can answer questions that were previously inaccessible experimentally - including questions about the relationship between quantum mechanics and relativity. The theory of relativity works well when you want to explain cosmic-scale phenomena - such as the gravitational waves created when black holes collide.

JUICE Magnetometer Successfully Commissioned in Space
By ÖAW A sensor developed for JUICE in Graz delivers a first quantum interference signal about a month after the launch towards Jupiter, thus achieving an important mission milestone. The European Space Agency's JUpiter ICy moons Explorer (JUICE) spacecraft has achieved another milestone. It started its eight-year journey to the Jupiter system on 14 April 2023 to explore the largest planet in our solar system and its icy moons - Ganymede, Callisto and Europa - which may offer the essential requisites for life.

On the trail of the origin of life
A team of scientists from Austria and France has discovered a new abiotic pathway for the formation of peptide chains from amino acids - an important chemical step in the origin of life. The current study provides strong evidence that this crucial step for the emergence of life can indeed take place even in the very inhospitable conditions of space.

Wandering celestial bodies provide a glimpse into the formation of stars and planets
With observations of one of the closest star-forming regions to the sun a team of international astronomers discovered the largest population of free-floating planets. These celestial bodies do not revolve around a star and are very hard to find due to their very low brightness. The large number of planets now detected provides information about the formation process of stars and planets and important information for future research.

How special are we?
Nearby star-forming region yields clues to the formation of our solar system A region of active star formation in the constellation Ophiuchus gives astronomers new insights into the conditions in which our solar system was born, showing how it may have become enriched with short-lived radioactive elements.

Space Weather: Reliable Predictions Thanks to Research in Graz
By Christoph Pelzl The influence of solar events on satellite-based applications such as orbit determination, telecommunications or navigation is being investigated by two research projects with the participation of TU Graz. Solar storms and similar events can cause sustainable damages to electronic systems on Earth, as well as on satellites.

Cat chases mouse in space
By Cornelia Kröpfl, BA MA If the groundwater rises sharply, flooding can be imminent. The Tom and Jerry satellites, chasing each other high above the earth, help make important predictions - including about climate change. Between 200 and 300 gigatons of mass is lost from Greenland each year. "A gigaton is an ice cube the size of a cubic kilometre," Torsten Mayer-Gürr makes this - literally - gigantic consequence of climate change strikingly clear.

How a ladybug warps space-time
Vienna quantum physicists measure the smallest gravitational force yet Researchers at the University of Vienna and the Austrian Academy of Sciences, led by Markus Aspelmeyer have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force.

Life of a pure Martian design
Experimental microbially assisted chemolithotrophy provides an opportunity to trace the putative bioalteration processes of the Martian crust. A study on the Noachian Martian breccia Northwest Africa (NWA) 7034 composed of ancient (ca. Gyr old) crustal materials from Mars, led by ERC grantee Tetyana Milojevic from the Faculty of Chemistry of the University of Vienna, now delivered a unique prototype of microbial life experimentally designed on a real Martian material.

Laboratory experiments could unravel the mystery of the Mars moon Phobos
What causes the weathering of the Mars moon Phobos? Results from TU Wien give new insights, soon a spacecraft will retrieve soil samples. Of course, there is no weather in our sense of the word in space - nevertheless, soil can also "weather" in the vacuum of space if it is constantly bombarded by high-energy particles, such as those emitted by the sun.
