Astronomers have a love-hate relationship with the atmosphere: it's great for, you know, not dying, but it blurs astronomical images. In the latest episode of Chasing Starlight we tell you the inner workings of adaptive optics, a technique where we use powerful lasers and fast shape-shifting mirrors to measure and correct atmospheric turbulence:
That's a new one:
"Hi Dr. Grinberg,
I came across your work while reviewing public academic records and researcher profiles.
Your research appears to have an established presence, but I couldn’t find a Wikipedia page providing a broader overview of your career.
I work with researchers on Wikipedia assessments and article development within editorial standards.
I can provide a short assessment if useful."
-- paid wikipedia pages for scientists are a thing now?

#Introduction Hi #fediverse ! We’re the European Southern Observatory, and we design, build and operate ground-based telescopes.
One of them is our Extremely Large Telescope, currently under construction in #Chile. It will have a 39 m mirror, and its rotating enclosure will weigh 6100 tonnes, or about 700 mastodons!
We’re looking forward to chatting with all of you about #astronomy

#HappyNewYear 🎉 Boost your #NewYear resolution with adaptive optics. By deforming a thin flexible mirror a thousand times per second you can correct atmospheric turbulence and get sharp astronomical images!

Need more galaxies in your feed? Of course you do.
Over the break I made @ArpBot, mostly because I thought the name "Arp Bot" was funny.
It posts an image of a galaxy in Halton Arp's Atlas of Peculiar Galaxies twice a day. Images are from the archives of professional observatories and the original 1966 catalog. I curated the images and wrote the image descriptions and most of the alt text.
Give it a follow!
Astronomers have long thought that the upper clouds of Jupiter, which create the planet’s iconic pale brown belts, are made of frozen ammonia.
But the joint efforts between an amateur astronomer with his backyard telescope 🔭 and professional scientists with ESO's Very Large Telescope (VLT), have now shown that they're actually made of something completely different 😲
Most likely, they are made of ammonium hydrosulphide mixed with smog, although vertical convection can sometimes bring ammonia ice clouds to the top.

At the Max Planck Institute for Solar System Research, we do cutting edge scientific research on our Sun, the planets and their moons, asteroids and comets. Posts will be in English und manchmal auch auf Deutsch.

In this week’s public lecture, #mpsgoettingen scientist Paul Hartogh takes us on a trip through the extreme atmosphere of #Venus. Is there evidence of life in the planet’s clouds of sulfuric acid? Find out more this Thursday! In German.

Since this https://chaos.social/@Skorpy/115037963703138114 is getting some traction right now, I would like to alert #astrodon folks that I have created this starter pack https://fedidevs.com/s/NjA2/ and that you may be in it: for a *very* loose definition of Germany, it's "Astronomy in Germany".
Accounts that have opted in to discovery features can be added to starter packs without further confirmation. So if you find yourself a part of this and want me to *remove* you, please let me know and I'll try to do this quickly, before it spreads too widely.
If you think you should be on that list, but are not, because of oversight on my part, or because of missing opt-in to account discovery so far, which you would now like to change, also feel free to let me know.
The idea is to have a presentable starter pack ready at the time of #ag2025goerlitz for https://ag2025.astronomische-gesellschaft.de/view_abstract.php?id=39
On the occasion of the International Annual Meeting of the German Astronomical Society, where a joint effort is happening right now to connect existing #fediverse accounts and to invite more members of the community to participate, here is a starter pack of accounts with a relation to Astronomy in Germany:
Are you all already following each other? Did you just get started and want to ask to be included, too? Would you like to suggest further additions to the starter pack? Are you discovering accounts in the list whose introductions should get boosted around a lot more? Are astronomy aficionados out there finding this list useful?

#MPSGoettingen wishes you happy holidays and a healthy and successful New Year 2026!
Featuring prominently on our season's greetings card: the first images of the Sun's south pole 🛰️ ☀️
During its flyby of the Sun at the end of March this year, the Solar Orbiter space probe had its first clear view of our star's poles. Solar Orbiter's trajectory has recently been tilted 17 degrees relative to the Sun's equator, allowing measurements from this unique perspective for the first time. As the new observations impressively show, the magnetic field at the poles is currently in a state of turmoil.
In addition to the images of the sun's south pole taken by the Solar Orbiter spacecraft, the past year has brought us many other highlights: exciting scientific results and important awards. Read more at https://www.mps.mpg.de/en/season-s-greetings-2025

TFW you get to use a 1950s survey scope to pin azimuth for true north on an incoming Sundial.
A bit of fun, this Wild Heerbrug T3 (yes, that's its name) #canada government scope was donated to #yorkuniversity in 1980s, when the original York Sundial still existed.
Now we're getting a BIG Sundial and using a bit of the 50s from the 80s to align azimuth.
The location is awesomely aligned with @AllanICarswellObservatory for likely obvious reasons 😀 #astronomy #Astrodon #science #sundialsunday
Happy birthday to #GW250114 our loudest detection to date!
In this video, Dr Becky Smethurst explains how we used the signal to test one of Hawking's fundamental ideas about black holes

Astronomy and Space: https://fedidevs.com/s/NjA2/
Physics: https://fedidevs.com/s/ODg2/
As I find I am running into limits with pinned posts, I've decided to consolidate three starter packs I like to recommend into this one single post. Enjoy!
