By the way one of the best-of-todays-posts was from the Hungarian #Astronomy Association informing everyone that the #constellation names have served no useful scientific purpose for the last centuries so all the constellations will be discontinued by the IAU, effective today.

What is "normal" anyway?

Astronomers have found multi-planet systems around a number of nearby stars, but none that's much like our own. They're not a lot like each other, either.

We still don't know what a normal planetary system looks like, or if there even is such a thing.

We highlight the disparate architectures of the highest-known multiplicity planetary systems, as well as a few systems similar to TOI-1136. We highlight that the candidate seventh planet in TOI-1136 does not have a confidently detected orbital distance. Planet and stellar radii are scaled for comparison to other systems, though we emphasize that the planet-star size is not to scale. None of the systems exhibits a clear analog to any of the others, and all have the potential for very interesting, future study. — UC Irvine

Unraveling The Mysteries Of Planet Formation And Evolution In A Distant Solar System - Astrobiology

A recently discovered solar system with six confirmed exoplanets and a possible seventh is boosting astronomers’ knowledge of planet formation and evolution.

Ooh, look I read another paper. Hurrah !

This one is about an incredibly, superlatively faint galaxy discovered back in 2018 that I'd forgotten about completely. Here the authors use Hubble observations to rule out an old stellar population - it only has young stars. This most likely means it's a tidal dwarf, having just recently formed due to tidal interactions but not likely to last long.

It's hard to comprehend the vastness of space. A new atlas helps, a little.
The Siena Galaxy Atlas contains the most precise overview of galaxies in the nearby universe: 380,000 of them, each one as vast and storied as our own Milky Way. https://noirlab.edu/public/news/noirlab2328/

Optical mosaics of 42 galaxies from the SGA-2020 sorted by increasing angular diameter from the top-left to the bottom-right. Galaxies are chosen randomly from a uniform (flat) probability distribution in angular diameter. The horizontal white bar in the lower-left corner of each panel represents 1 arcminute and the mosaic cutouts range from 3.2 to 13.4 arcminutes. This figure illustrates the tremendous range of types, sizes, colors and surface brightness profiles, internal structure, and environments of the galaxies in the SGA.

Like many other scientists I often get "debate me" emails from random people with weird ideas about #astronomy. If I answer, they feel validated. Same if I don't. So I always pick the option that doesn't waste my time. Don't fall for the "debate me" trap, folks, you can't win. #scicomm

Galactic collisions result in a billion-year gravitational dance, as shown in this captivating supercomputer simulation. The simulation depicts the collision of two spiral galaxies and is complemented by actual images of galactic collisions at various stages captured by Hubble.

The universe is wild.

This streak on a Hubble photo, originally thought to be an imaging glitch, is actually a 200,000 light year trail of new stars formed by the wake of a black hole that was ejected from the galaxy at the top right.

For reference, that streak is about twice the diameter of the Milky Way!

Vera Rubin was an American astronomer whose pioneering work on galaxy rotation rates provided the first evidence for the existence of dark matter.

This seminal breakthrough led to the creation of a whole new field of astronomy, as her once-startling theory became an accepted part of the still-evolving story of the universe.

Favored to win the Nobel Prize for years, she died in 2016 without ever receiving a call from Stockholm.

Also looks like someone at the UK's Royal Astronomical Society set up a Mastodon account and is crafting custom posts for it, but it only has ~300 followers compared with their >50K on Twitter:

@royalastrosoc

I see this all too often -- major public/nonprofit organizations set up shop here, but don't know how to best cross-link/promote it, so the accounts get kind of lost. If you care about #astronomy & like their work, give them a boost or follow 😀

#JWST reaches new milestone in quest for distant #galaxies.

The light from these galaxies has taken more than 13.4 billion years to reach us implying they existed 400 million years after the big bang, when the #universe was only 2% of its current age.

These galaxies are extremely faint because of their great distance from us. Astronomers can now explore their properties, thanks to JWST's exquisite sensitivity.

I have rediscovered Celestia 🌠 (https://celestia.space/), the absolutely mindboggling #astronomy simulation for #linux and game consoles (aka. windows®). For more than a decade it has been removed from #debian but after a todays mention (and in fact I had to figure out its forgotten name) I realised that they again offer fresh working versions for download. 🤩
And I am speeding through the galaxy arm right now at about 500 ly/s. 😁 (That's about 10^10 c.)

Celestia: Home

Celestia is a free space simulator for Windows, Linux, macOS, iOS and Android. You can freely explore space in three dimensions. The program displays objects and orbits based on scientific data.
