The fascination of astronomy
Anyone who has ever experienced the fascination of astronomy under a clear starry sky will not let go of it.

Our "Sternstunden" make astronomy tangible for everyone - wander together into the distance...

- Reproducibility of transit light curves for the detection of exoplanets
The transit light curves of five exoplanets are evaluated for their reproducibility. The parameters examined are the indirectly measured radius of the respective planet and the temporal center of the transit. After a detailed treatment of the individual exoplanets, a summary of the measurements shows that the respective planetary radius was measured reproducibly in 10 of 12 measurements. - Visit to the Physikalisch-Technische Bundesanstalt in Braunschweig on 7 July 2025
Meter, kilogram, second, ampere, mole, kelvin, and not to forget the candela. These are the units of measurement of the International System of Units (SI – Système international d'unités). Astronomers have encountered almost every one of them at some point. Considering this, it's easy to understand why, for us at kosmos-os, the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig, one of the internationally most important metrology institutions, is an attractive destination for one of our excursions.
