Updated diagram version for #SciComm usage!
Have stitched together the annotated image, along with that excellent diagram from The Planetary Society.
Someone said to me last night that this looks like a half-cut avocado, and now I cannot unsee it lolololol
Such a great image, and another fine example of how physics allows us to see around corners!

Whooooaaaa! The new #JWST image is so good! So much physics going on — physics Einstein himself thought about!
This is called an Einstein Ring. When a massive foreground galaxy (in this case, an elliptical galaxy) warps the space-time around it, light from behind it bends in our direction.
The JWST caught this fantastic example, where the background spiral galaxy is getting warped into our view. It appears as a ring, but we can see its structures like its spiral arms, gas features and star clusters.
Incredible science happening here!

I added the annotations in the second image.

Forecast noted cloudy last night. Took a peak outside this morning and was able to sneak in 30 minutes of telescope time. Decided to observe some #galaxies i have observed before. Here is #m104 #SombreroGalaxy . #unistellar #odysseypro #space #astronomy #amateur
[Zoom on the #CosmicWeb] Have you dived into the deep fields of #Euclid revealed this Wednesday by the @ec_euclid ? Have you navigated between the thousands of #galaxies of different shapes, sizes, colors and masses? So many objects, near and far, fill our #Universe! https://sky.esa.int/esasky/?hide_welcome=true&hide_banner_info=true&hips=DES-DR2+ColorIRG&sci=false&layout=esasky&euclid_image=EDFS
What if their spatial distribution could tell us something about two mysterious components : #DarkMatter and #DarkEnergy? This is the gamble taken by the scientists involved in the Euclid mission. To do so, they've designed some unrivalled #instruments: a camera with great depth of field and high resolution records the variety of shapes and spatial distribution of galaxies, while a #spectrometer coupled with a #photometer can determine the distances and masses of galaxies ...

My mind is still a bit blown from #Euclid telescope images last night.
When I zoomed in on a tiny patch of sky — field of view: 7.1' x 3.6, which is about the size of a grain of rice held at arms length — there was so much to see.
Walls and walls of galaxies. And then more walls of galaxies behind this.
Each galaxy hosts hundreds of billions of stars and there are millions of them, all, in this tiny field of view.
We are tiny tiny creatures.
In the next few months, from its perch atop a mountain in Chile, the Vera C. Rubin Observatory will begin surveying the #cosmos with the largest camera ever built.
Every three nights, it will produce a map of the entire southern sky filled with #stars, #galaxies, #asteroids and @supernovae — and swarms of bright #satellites ruining some of the view.
Swarms of satellites are harming #astronomy.
Here’s how researchers are fighting back.
A trio of #galaxies observed this evening. #NGC0925 , #NGC0936 and #NGC1023 . #unistellar #odysseypro #space #astronomy #amateur
Some scientific discoveries shake up my brain.

On the one hand, it almost blows my mind when I think about it further. On the other hand, it's wonderfully reassuring to realise that there are a lot more important and fascinating things in this cosmos than some evil guys on two small legs.
Beautiful new cover of the Nature Astronomy Journal
Galactic fireworks from Cosmic Dawn: 13.4-billion-year-old photons reveal the extreme conditions in one of the most distant known galaxies.
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!
Trío evolutivo porque son molones y ya está.
Zubat, Golbat y Crobat. No en la misma posición.
Wowzer! Map of cosmic flows, by yours truly, makes it to the cover of the Nature Astronomy journal.
"Galaxies from
wherever flock
together"

[Le #JWST, booster de connaissances !] Depuis sa mise en service en juillet 2022, le James Webb Space Telescope a dévoilé un nombre inattendu de #galaxies anciennes et de #TrousNoirs supermassifs dans l' #univers jeune, l'abondance de #molécules carbonées au sein des #DisquesProtoplanétaires, la composition chimique de l' #atmosphère d' #exoplanètes proches de la Terre, etc.
Le journal du @cnrs revient sur l'ensemble de ces découvertes avec quelques-uns des scientifiques impliqués - notamment Olivier Berné, astronome à l'IRAP.
Bonne lecture
