Microbes leave "fingerprints" on Martian rocks
Scientists around Tetyana Milojevic from the Faculty of Chemistry at the University of Vienna are in search of unique biosignatures, which are left on synthetic extraterrestrial minerals by microbial activity. The biochemist and astrobiologist investigates these signatures at her own miniaturized "Mars farm" where she can observe interactions between the archaeon Metallosphaera sedula and Mars-like rocks.

Four years in space: Austrian BRITE satellites
Four years in space: Austrian BRITE satellites
TUGSAT-1 and UniBRITE have been in space since 2013. During this time 350 stars have been observed, new variable stars discovered, and 12 scientific papers published in international journals. The nanosats of the BRITE mission focus on the brightest, hottest and most massive stars in the immediate neighbourhood of the universe.
