TöpferDie Bedeckung der #Venus durch den #Mond war soeben nicht leicht zu beobachten, weil unser Trabant sich als schmale Sichel gezeigt hat. Mithin fiel auf, dass die Venus eine deutlich höhere Albedo aufweist als der Mond. #astronmy #Astronomie

Astronomer, Reinvented#astronmy I then tried framing mode with the Seestar S50 on M44. The best shot was 45 minutes exposure of overlapping frames.

Scenarios of future annual carbon footprints of astronomical research infrastructures
Research infrastructures have been identified as an important source of greenhouse gas emissions of astronomical research. Based on a comprehensive inventory of 1,211 ground-based observatories and space missions, we assessed the evolution of the number of astronomical facilities and their carbon footprint from 1945 to 2022. We found that space missions dominate greenhouse gas emissions in astronomy, showing an important peak at the end of the 1960ies, followed by a decrease that has turned again into a rise over the last decade. Extrapolating past trends, we predict that greenhouse gas emissions from astronomical facilities will experience no strong decline in the future, and may even rise substantially, unless research practices are changed. We demonstrate that a continuing growth in the number of operating astronomical facilities is not environmentally sustainable. These findings should motivate the astronomical community to reflect about the necessary evolutions that would put astronomical research on a sustainable path.

@nasa if your toots included the image preview a lot more people would be amazed:

NaztronomySending out my final batch of solar eclipse glasses. Thanks to everyone who participated. I'm estimating that I gave away about 270 pairs between the annular eclipse and this upcoming one (in person and by mail). Mailed ones get a nice JWST stamp.
