Exciting news! Introducing AstroVisBench: A Code Benchmark for Scientific Computing and Visualization in Astronomy!

A new benchmark developed by researchers at the NSF-Simons AI Institute for Cosmic Origins is testing how well LLMs implement scientific workflows in astronomy and visualize results.

My periodic reminder for #astrosci #astrodon #exoplanets Early Career Researchers to please, please, please have a simple web site with your current email address on it - rationale here: kenworthy.space/advice/
A pen sketch of a web page for an astronomer, showing name, email, optional phone number, and professional contact details, with a one sentence summary of their research and an ADS link.

Yay! Now I'm allowed to reveal that DESI found stronger constraints toward evolving dark energy. It's not quite at the five sigma level yet but may have "major implications for our understanding of the nature and fate of our universe" 🚀🔭

🔭 Crowdsourcing here a little: Astro folks! Do you have a favorite online resource/publication for astronomy info to share with the general public?

I have a science museum volunteer who's interested in updating the sources they share with folks who want to learn more, and astrobites is my default

Image by Michael Carroll shows some asteroids to scale. We did NOT see the little one coming & it hit Earth above Chelyabinsk in 2013, injuring >1400 people. Asteroid 2024 YR4 is bigger than the little one, perhaps as large as the football field! JWST 🔭 data next month will help pin down the size.
Image by Michael Carroll illustrating the sizes of some asteroids in 2013. The asteroids are shown in comparison to a US football field. We had seen the big one coming, and it just buzzed Earth. But the littler one we did NOT see coming, and it hit Earth above Chelyabinsk, creating a shockwave the blew out windows and injuring more than 1400 people. The asteroid we are monitoring now - 2024 YR4 - is bigger than the little guy, but maybe as large as the whole football field! Our JWST measurements next month will help pin down the size.

Very proud of Isabella's work which she started during a TIMESTEP internship at NOIRLab last summer. She wrote a very nice Jupyter notebook on galaxy quenching featuring the SDSS "cosmic slime" estimates of matter density. Check out her #aas245 iPoster 465.04 (notebook linked in short thread below)

📣Undergrad student Isabella Olin is presenting her #aas245 iPoster 465.04 soon (1-2pm) on SDSS/BOSS Large Scale Structure and the "Cosmic Slime" Value-Added Catalog, where she investigates the impact of environment on galaxy quenching

She contributed a new Jupyter notebook on her work (link below)

For those who missed it, this is the stunning image from Webb's NIRCam showing NGC 604, a star-forming region located around 2.73 Mly away in the Triangulum galaxy (M33).

This is an image from JWST’s NIRCam (Near-Infrared Camera). It features the star-forming region NGC 604 and shows how stellar winds from bright, hot, young stars carve out cavities in surrounding gas and dust. The most noticeable features are tendrils and clumps of emission that appear bright red, extending out from areas that look like clearings, or large bubbles in the nebula.

When bacteria was found on an asteroid Ryugu grain in London, the media questioned whether terrestrial contamination was ever avoidable. No contamination has been found at JAXA. But let's take a look at what that takes... brace yourself (my latest on Cosmos 🧪🔭🛰️)

We've just released the third band of the Rapid ASKAP Continuum Survey! This is the new #RadioAstronomy reference survey of the sky, south of declination 40 degrees.

Here are some typical images...

@sunmish.bsky.social @elenchically.bsky.social @cosmicpudding.bsky.social @redqso.bsky.social
6 images from the "Rapid ASKAP Continuum Survey". The top row shows the RACS high band, mid band and low band images of radio source PKS J0816−7039. The bottom row shows the RACS high band, mid band and low band images of radio source PKS J2113+0230. The colour scheme ranges from pale to dark purple. Image credit: Stefan Duchesne

IC 5068, the Forsaken Nebula

Just seems appropriate for the now-ishness of right now

Seestar, 3.2h 🔭
A red square-shaped cloud of glowing gas is centered and nearly fills the image. Dark tendrils of dust eat into its sides from the blackness of the background. Stars of different colors and brightnesses are scattered across the frame.
