More information on this first release of a batch of survey data, including a preview of Euclid deep fields:
Yes, the data is publicly available!
Euclid ‘quick’ releases, such as this, are of selected areas, to demonstrate the data products to be expected in the major data.

This photo is insane. Dude went to Alaska to capture the #eclipse and the Northern Lights appeared behind it.

18/03/2025 - We had another visit to the Pacman Nebula tonight. This time no moon and clear sky. Really happy with the photo. Nebula looks so nice and the amount of stars round it, wow! The night sky really is a big place just full of lovely stuff. We tried a new dark spot on the hill this evening, not as far as my ankle is still a problem. Turned out a pretty good place for the scope.
Messier 97, also known as the #OwlNebula, is a planetary nebula located approximately 2,030 light-years away in the constellation #UrsaMajor that reaches its annual culmination at astronomical midnight and is best observed around March 8th.

Okay, I need your help!
I am finalising my PhD thesis at the moment, and it is "tradition" to have a quote at the beginning of each chapter. Now I want to be difficult: I want quotes from FEMALE astronomers / scientists talking about astronomy.
Shoot me your favourites pls
This fab animation by Tony Dunn shows the orbital patterns of Saturn's newfound moons.
There are a lot of them! But if you count every meter-scale object in Saturn's rings as a "moon," then Saturn really has...oh, about 10 quadrillion moons.

@Radboud_uni That’s how the astro coffee table @Radboud_uni was looking when one professor from the Cologne area, who shall remain unnamed, brought sweets from the carnival parades. And the table a few days later …

How does a Coffe table look like in an astrophysics department at @Radboud_uni ? Full of puzzles! In this particularly nasty case a puzzle that came out of a PhD thesis making use of LOFAR data to study the magnetic field in our Milky Way …

ESO analysis confirms that the INNA industrial megaproject would have a devastating and irreversible impact on the facilities at Paranal Observatory in #Chile.
Light #pollution would increase by at least 35% above ESO's Very Large Telescope, by a minimum of 5% above ESO’s Extremely Large Telescope and by at least 55% above the south site of the Cherenkov Telescope Array Observatory
Air turbulence would also increase, degrading seeing conditions by up to 40%
Vibrations from the project could seriously impair the functioning of the ELT and the VLT Interferometer, which are both extremely sensitive to micro-seismic noise.
Dust during construction is also problematic as it settles on the telescope mirrors and obstructs their view.

The lasers our Very Large Telescope (VLT) pierce the Milky Way… but what is that vertical glow just below?
That’s the zodiacal light: caused by dust grains in the Solar System, it's so faint that it’s only visible in the darkest skies, such as those of Chile’s Atacama Desert.
And the pristine night sky in this region has always been intertwined with the culture and traditions of its indigenous people, discover how: https://www.eso.org/public/images/potw2511a/
