The open star cluster Messier 21 as imaged by the Vera C. Rubin Observatory
Located near the Trifid Nebula, Messier 21 is relatively young and tightly packed with small, dim stars.

Rubin observatory unveils first images taken with its giant mirror and camera
Pictures are a prelude to a transformative, all-sky survey set to begin in months. More images and videos will be revealed in a livestreamed event today.

Manchmal muss man sich als Hobbyastronom auch mit irdischen Dingen wie der Gartenarbeit befassen. 
Doch auch eine Sternwarte kann dabei ihren ökologischen Beitrag leisten: seit diesem Jahr lassen wir auf ungenutzten Flächen die Wiese wachsen! 
Besucht uns doch mal, ob zum Sterne- oder Blütengucken!

The 4 biggest mysteries the new Vera Rubin Observatory could solve
No telescope has basked in the night sky quite like this before. Here's what it could reveal about the universe.
Just two days to go before the public reveal of the first images!

A Glimpse of CLIMSO
* Image Credit & Copyright: Alain Sallez (picdumidi.org)
Explanation:
A tantalizing glimpse inside this dome was captured after sunset at the mountain top Pic Du Midi Observatory in the French Pyrenees. But while most are just beginning their work at sunset, this observatory's day was done. The instrument looming within is CLIMSO (for Christian Latouche IMageur Solaire), dedicated to exploring dynamic phenomena across the surface and atmosphere of the Sun. To image the solar atmosphere or corona, CLIMSO uses coronagraphs. Developed by French astronomer Bernard Lyot in the 1930s, coronagraphs block light from the center of the telescope beam to create an artificial solar eclipse and allow a continuous view of the solar corona. In this surreal twilight scene above a sea of clouds, the dome's interior was revealed by the single, long exposure as the open slit rotated across the field of view. https://eclipse.gsfc.nasa.gov/OH/OH2011.html#SE2011Nov25P

Hi Mastodon! 
New instance, new #introduction 
We have just left astrodon.social, which is closing down, to find a new home at scicomm.xyz. Thanks!
We are the OST (Overwhelmingly Small Telescope) Observatory at the University of Potsdam in Golm, on the outskirts of Potsdam, Germany.
Our main telescope is a PlaneWave CDK20 Astrograph. We focus on educating students in astronomy and supporting both undergraduate and postgraduate projects. We occasionally capture and share astronomical images, and we are excited to post some of them here.
We are also passionate about science outreach and regularly participate in public events such as the Potsdam Day of Science and the Long Night of Astronomy.
Follow us for updates in both English and German!
On 
June 23 the @VRubinObs #observatory will unveil a first look at ultrahigh-definition images and videos of the cosmos taken from a mountaintop in #Chile. And you can participate by joining a public livestream (in English and Spanish) or one of the in-person watch parties at #planetariums, #universities and #museums 
around the globe. https://www.scientificamerican.com/article/see-vera-c-rubin-observatorys-first-images-live-with-these-watch-parties/
