Most of the galaxies in the universe rotate in the same direction. Why this happens highlights a gap in our understanding of how the universe works. "It is still not clear what causes this to happen, but there are two primary possible explanations," says astronomer Lior Shamir of Kansas State University. @ScienceAlert explores both:
Oh my... it's full of Galaxies!

So last night we put our #Dwarf3 telescopes on the studio roof at the back of the house, loaded up some schedules, and let them go all, night.
Inspired by @malcircuit 's post a little while ago, one of the targets I programmed in was Markarian's Chain, a string of galaxies.
This is 170x60s@gain 60, post processed using the automated online denoising tool that Dwarf have made available, and finished off in #Snapseed
Webb reveals unexpected complex chemistry in primordial galaxy
(... what we think of as the "first billion years" of the universe probably took a more billion years than that)

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
(19 Mar) Euclid’s First Big Data Drop Maps 26 Million Galaxies to Illuminate the Dark Cosmos

[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.
A European space telescope launched to explore the dark universe has released a trove of new data on distant galaxies. @AssociatedPress :

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.
Galaxies in Space
The plane of our Milky Way galaxy extends beyond the limb of planet Earth in this space age exposure captured by astronaut Don Pettit. His camera, with low light and long duration settings, was pointed out the window of a Dragon crew spacecraft docked with the International Space Station on January 29. The orbital outpost was at an altitude of about 400 kilometers above the Pacific Ocean at the time.

I had the pleasure to be interviewed by Alexandre Morales for France Culture, to talk about the discovery of Quipu, one of the largest known structure of the Universe. It will air tomorrow morning at 6:52.
