Liquid water is one of the most important ingredients for the emergence of life as we know it on Earth. Researchers of the ORIGINS Cluster from the fields of astrophysics, astrochemistry and biochemistry have now determined in a novel, interdisciplinary collaboration the necessary properties that allow moons around free-floating planets to retain liquid water for a sufficiently long time and thus enable life.
How are galaxies born, and what holds them together? Astronomers assume that dark matter plays an essential role. However, as yet it has not been possible to prove directly that dark matter exists. A research team including Technical University of Munich (TUM) scientists has now measured for the first time the survival rate of antihelium nuclei from the depths of the galaxy – a necessary prerequisite for the indirect search for Dark Matter.
What tasks can nanosatellites perform around the moon or even further away from Earth? A new study at the University of Würzburg aims to clarify this.
Wax flowers and numerous plant genera related to them evolved about 33 million years ago. Shortly thereafter, they split into three independent evolutionary lineages, according to a new international study led by Bayreuth plant systematist Prof. Dr. Sigrid Liede-Schumann. A total of 37 genera and 740 species emerged, distributed over the tropics and subtropics worldwide. Only the combination of well-established morphological studies with the latest molecular genetic analysis methods ensures a correct taxonomic description and classification. The research results have been published in the journal "Taxon".
Long periods in space damage bone structure irreparably in some cases and can make parts of the human skeleton age prematurely by up to 10 years. This is what a sport scientist at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) has now discovered in conjunction with other researchers from Germany, Canada and the USA. Adapted training programs in conjunction with medication could provide better protection for astronauts on future space missions. The researchers have published their findings, which will now be also be used for treating rheumatic conditions in clinical practice, in the scientific journal Nature Scientific Reports.
Neutrinos that reach our planet from the depths of the Universe originate from blazars. Astrophysicists have proven this for the first time.
Lots of little dots with no apparent pattern: where laypeople may just see milky gray photos sprinkled with what looks like random crumbs, it is enough to make astronomers’ hearts miss a beat. We are talking about historical photographic plates showing negatives of the night sky. Together with the Leibniz Institute for Astrophysics Potsdam and the universities of Hamburg and Tartu (Estonia), researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have digitized the images and published them online. After a total of 10 years, the project has now been completed successfully, thanks to the financial support of the German Research Foundation (DFG).
What steers galaxies, or whole ensembles of galaxies - so-called galaxy clusters? Aren’t they surrounded by vast empty space? Could the recently discovered long hot interconnecting gas filaments play a role? Although cosmological models and simulations predicted these structures and the role they may play, the observational confirmation of their existence, using the x-ray space telescope eROSITA, is quite recent. Further snapshots of simulations compared to the observations unveil a galaxy group speeding along such a long gas filament, on a collision course with other galaxy clusters.
More than half of the matter in our Universe has so far eluded our view. Astrophysicists have predicted however where it might be: in so-called filaments, unimaginably long structures made of hot gas that surround and connect galaxies and galaxy clusters. These filaments of hot gas in the computer simulations by Dr. Veronica Biffi and PD Dr. Klaus Dolag at the ORIGINS Cluster of Excellence are strikingly similar in their structure to the 50 million light years long filament which has now been observed for the first time by a team led by the University of Bonn using the eROSITA space telescope.
