It's #WorldTurtleDay! In 1754 the English botanist and author John Hill proposed a new constellation he called "Testudo" (the Tortoise). It didn't catch on with astronomers, but under dark night skies it can still be seen. Read more about it: https://unchartedconstellations.com/
This is the Owl Nebula from last night. It is about 2000 light years away and about 2 light years in diameter. It formed about 8000 years ago from gases ejected from a star.
Finally, after months of work, the #ESAEuclid Early Release Observation images, data, first science results, and #Euclid mission reference papers have been released. You can read more in our blog post, which has links to the papers, the press releases, and everything else:

J'ai pu faire un #timelapse des #aurores polaires de la nuit du 10 au 11 mai. Je les ai mis en ligne. En réalité les prises de vues s'étalent sur 1h20. Je ne m'attendais pas vraiment à l'ampleur du phénomène donc le cadrage n'est pas idéal.
Tomorrow, 23 May, 12:00 CEST, #ESA and the @ec_euclid will present 15 papers, including first #astronomy results:
5x #ESAEuclid reference papers about the main mission, the instrumentation, and related cosmological simulations
10x Early Release Observation #science papers, ranging from ... near to far
At the same time ESA will make 5 new ERO images public and the underlying science images. This programme was observed before the start of Euclid's main survey.
I guess those are just the graphical representations, and they're more likely just rather close together. :)
Objects in the app may be smaller than they appear.
An article published in the journal "The Astrophysical Journal Letters" reports the results of observations of a structure similar to a chimney which functions as a sort of vent from which hot gas coming from Sagittarius A*, the supermassive black hole at the center of the Milky Way, escapes.

it was atypical until a couple of years ago, with a typical number of ~10 projects, but then after the boost from the EU recovery fund + projects funded by ERC projects we got to 16 in 2022, 19 in 2023 and now 17.
The whole area has ~200 staff astronomers.
Bud indeed I agree that's a lot of project and students to look after...
A nomenclature of 'Blue Moon' almost never means a Moon of a blue color but with the summer nights, a literally blue appearing Moon, or Moon in the daytime is a fun one to spot. The northern hemisphere was showing off a bit before sunset, and with the May 23 full Moon so close I couldn't resist a few pictures. Happy lunar viewing! #astronomy#Astrodon#moonlight#lunar#bluesky#bluemoon
This image shows Gum 46, also cataloged as RCW 71, an impressive gas cloud located at a distance of about 5,500 light years from Earth and located in the direction of the Crux Constellation, revealing details thanks to the skill of astronomers Mark Hanson and Alexandr Zaytsev. At the heart of Gum 46 is a young, hot, blue star called HD311999, both the star and..... #astronomy#space#astrophysics#astrophotography
