The skies of Chile’s Atacama Desert, renowned as the darkest and clearest of the world, are now at risk from an industrial megaproject.

Electricity company AES Andes proposed to locate a large-scale industrial complex just a few kilometres away from our Paranal Observatory. If constructed, the resulting dust emissions, increased atmospheric turbulence, and especially light #pollution, would irreparably impact the capabilities for astronomical observation.

We urge the involved parties, specifically AES Andes, to work with the Government of #Chile to relocate this megaproject to a zone compatible with industrial development without jeopardising the skies of Paranal.

German astronomer Maria Kirch died #OTD in 1720.

She was one of the first famous astronomers of her period due to her writing on the conjunction of the sun with Saturn, Venus, and Jupiter in 1709 and 1712 respectively. Kirch observed a comet in 1702, becoming the first woman to make such a discovery. However, the discovery was officially credited to her husband, reflecting the gender biases of the time.

This is a portrait of a young woman dressed in historical attire. She appears to be seated, holding a brush or pen in one hand and possibly working on a sketch or painting on the surface in front of her. Her gaze is directed toward the viewer, and the background is dark, emphasizing her figure and expression.

I feel like we could all use some good news right now, so here you go: Bright comet Tsuchinshan-ATLAS will become visible in the evening sky starting tomorrow night.

Clear view to the west essential. Sharp eyes highly recommended. Pointers at the link.

https://skyandtelescope.org/press-releases/bright-comet-evening-view/ #space #science #astronomy #nature #photography

The bright Comet Tsuchinshan-ATLAS will first become visible in the evening sky on October 11th, appearing between Antares, the brightest star in the constellation Scorpius, and Arcturus, the brightest star in Boötes. While opening night will have it competing against twilight, it will be both higher in the sky and more visible against darker skies on subsequent evenings.

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

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:

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 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.
