  • Exkursion zur Olbers-Gesellschaft Bremen am 22. April 2025

    Excursion to the Olbers Gesellschaft Bremen on April 22, 2025

    Ursprünglich hatten wir nur die Teilnahme am Vortrag „Die Vermessung des unsichtbaren Universums mit Hilfe von Gravitationswellendetektoren“ bei der Olbers-Gesellschaft e. V. in Bremen geplant. Da wir wussten, dass der Vortrag in dem Gebäude der Hochschule Bremen stattfinden würde, in dem auch die Walter-Stein-Sternwarte beherbergt ist, hatten wir angefragt, ob eine kurze Besichtigung der traditionsreichen…

  • Groß, schwarz, heiß und mit  kurzer Lebenserwartung

    Big, black, hot and with a short life expectancy

    The measurement of the transit light curve of the exoplanet Wasp-12b is described. This exoplanet is special in many ways. The large number of existing transit light curves, including our own measurements, enables spectacular predictions about the lifespan of the exoplanet.

  • Messung der Transitlichtkurve des Exoplaneten TOI-2570 b

    Measurement of the transit light curve of the exoplanet TOI-2570 b

    The measurement of the transit light curve of the exoplanet TOI-2570 b, which was only discovered in 2022, is described. The brightness of the parent star, which is located in a very dense field of stars, was determined in 148 images in relation to comparison stars. The result agrees very well with the data known so far.

  • Besuch in meiner Sternwarte

    Visit to my observatory

    On Wednesday, October 16th, 2024, a volunteer from the Neue Osnabrücker Zeitung (NOZ) and a photographer were with me to report on my hobby of astronomy, the comet C/2023 A3 (Tsuchinshan-ATLAS) and the “supermoon”. The article should appear in the online edition of NOZ.

  • Aller guten Dinge sind drei

    All good things come in threes

    The sun has reached its maximum in its eleven-year activity cycle. For the third time this year, northern lights could be observed from Central Europe. A short excursion into the personal experiences of some kosmos-os friends at the Northern Lights on October 10, 2024 is presented.

  • Die Offene Sternwarte im Offenen Garten

    The Open Observatory in the Open Garden

    Im Osnabrücker Land werden in jedem Sommer viele private Gärten für die Allgemeinheit geöffnet. Ihre Besitzer haben sich im „Offenen Gartentor Osnabrück und Umgebung“ zusammengeschlossen. Jeder Interessierte kann so eine Vielzahl von Gartenideen kennenlernen. So auch am Sonntag, 4. August 2024, im Garten in der Moorlandstraße in Osnabrück. Die Besonderheit hier: Es gibt eine Gartensternwarte.

  • Mission EUROPA CLIPPER

    Mission EUROPA CLIPPER

    On Saturday, June 9th, 2024, kosmos-os provided information about a new spectacular NASA space mission to Jupiter's moon Europa in October 2024 as part of a lecture at the Innovations Center Osnabrück (ICO). In front of ten interested listeners, Dr. Achim Tegeler reported on the current status of the development of the Europa Clipper Mission. 

  • Messung der Transitlichtkurve des Exoplaneten TOI 3952.01 am 10.01.2024

    Measurement of the transit light curve of the exoplanet TOI 3952.01 on January 10, 2024

    The measurement of the transit light curve of the exoplanet TOI 3952.01, 1929 light years away, is described. It is a recently discovered exoplanet. The own measured data are compared with the few available literature values.

  • Kalte Füße und klamme Hände bei der Astrofotografie – das war gestern

    Cold feet and clammy hands during astrophotography – that was yesterday

    There are many garden observatories used by amateur astronomers and almost as many different concepts that are followed in their construction and operation. That's why it's always worth visiting such an observatory.

  • Am Polarkreis tanzt das Nordlicht

    The northern light dances in the Arctic Circle

    The report describes what has to be taken into account for successful sightings of the northern lights. In addition, factors that cannot be influenced, such as the weather and the space weather, are also mentioned. Recordings and videos of the northern lights are shown. In addition, numerous sources are listed for more detailed information.
