@MichaelPorter I'm sure I'll similarly see a few posts to tip me off if I'm on Mastodon at the time it breaks, but I wonder how one can find out in minutes rather than perhaps hours? Might be fun to code up an alert to tell my Home Assistant or to send me a text.
This image taken by the Hubble Space Telescope shows spiral galaxy NGC 4689. Resembling a cosmic fingerprint, this galaxy exhibits spiral arms branching in all directions, classifying it as a foculating spiral. Its position facing us offers astronomers an almost perfect view to study its structure in detail. The disk contains dense regions of gas, dust and..... #astronomy#space#astrophysics#astrophotography
I taunt astronomers in other EM regimes because unlike us cool radio astro folks, they mostly can't do astronomy during the day (where we can).
Now, folks from our uni (Macquarie Uni) and fellow PhD'er Sarah Caddy, are building telescopes for daytime obs.
THIS IS BETELGEUSE IN THE DAY! 🤯
To get these results, we've built a telescope that has MANY eyes, and named it after the huge spider we have here called 'The Huntsman' (which of course, has many eyes).
The image by astronomer Jerome Yesavage shows a low surface brightness planetary nebula cataloged as PN Kohoutek 1-16, located in the direction of the Draco Constellation and located at a distance of about 3,400 light years from the Solar System. The central star is a very hot pulsating star called DS Dra, it has a magnitude of 14.96 and is of spectral type..... #astronomy#space#astrophysics#astrophotography
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:
The summer 2024 NASA's Astrophoto Challenge is now open! This summer's target: Cassiopeia A.

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.
@richard
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

Messier 33, presented here in an excellent image by astronomer Alson Wong, is popularly known as the Triangle Galaxy. Its name is not only due to the fact that it is located in the direction of the Triangulum Constellation, but it is also the third largest galaxy in the Local Group, along with the largest, the Andromeda Galaxy Messier 31 and our Milky Way, with the..... #astronomy#space#astrophysics#astrophotography
