THis poster advertises the Geo SonNet Town Hall on December 15th 2025, from 18:00-19:00 in Room 243-244 Convention Center. Who should attend? Data scientists curious about sonification, researchers seeking more intuitive sound mapping options for complex datasets, existing projects looking for new collaborative partners. There are two QR codes, one to join the listserve, another for the Geo SonNet.

Heading to the @agu.org annual meeting, interested in using sound to help interpret your complex data, AND make your research more inclusive? Data sonification can help! But don't take my word for it: www.youtube.com/watch?v=X_eU...

Attend the Geo SonNet Town Hall on Dec. 15th to network!

Very cool data sonification of Roman science! But I really wish these had a short audio narration in front to provide context. Helps anyone watching this better understand the sounds, and if you are BVI this is just a bunch of weird noises!

A logo "HSLA" which stands for Hubble Spectroscopic Legacy Archive, has three stylized spectra with rainbow colors radiating from left to right. In the background are stars, galaxies, and a giant planet.

Hey #astrosci community! After working on this project for 3 years, there's a new Hubble Spectroscopic Legacy Archive that's just been newly made available at @stsci.edu: archive.stsci.edu/missions-and... follow me to learn more! (1/n)

We added some nice features to our JWST Search interface. HST rolling out in next couple months, along with more goodies.

Technicians recently tested two major deployments for the Nancy Grace Roman Space Telescope: the Deployable Aperture Cover (DAC) and the Solar Array Sun Shield (SASS): go.nasa.gov/41X95PN #NASARoman 🔭 🧪

When I decided to pursue astronomy as a career, inspired by Star Wars, there were no known real planets orbiting stars like the Sun. Now we can take baby photos and SEE them. Incredible, and building off of decades of work by others who came before to get us collectively to this place.

Four years' worth of Ca HK activity measurements with more planned on the way. Great dataset for anyone exploring stellar activity now at MAST!

@commondescentpod.bsky.social Motivation for a Silver Screen episode on Star Wars? Best Star Wars planets for optimal fossilization? What kind of dinosaur was Boba Fett riding in the Christmas Special? Were krayt dragons actually dragons? Dragon*con topic perhaps!? www.wired.com/story/an-anc...

The more we look with #NASAWebb, the more we find! The latest discovery? A tiny new moon orbiting Uranus. It’s just six miles (9.6 kilometers) in diameter: science.nasa.gov/blogs/webb/2... 🔭 🧪

An individual pulls tape from a dispenser at a desk with stacks of white boxes and astronomical images in the background.

A tactile panel of Uranus shows the blue planet and rings on a black background.

A tactile panel of Uranus shows the blue planet and rings on a black background. The image was taken from a side to show the three dimensional component. The panel is sitting on a wooden table.

Tim Rhue, education specialist at STScI, packs up new tactile panels based on the first #NASAWebb image of Uranus. These panels are being sent to museums, libraries, and other educational sites, so that they can share this tactile experience with their audiences. 🔭

Yes this, unlike other more common industries with much larger applicant pools, astrophysics (and things like software engineers applying their craft to a specialized field like this) is not something than can be restocked quickly en masse, and many who left won’t just come back from their new jobs.

MAST background in "standard" sky projection, in hues of blue. Lighter blue areas mark lots of observations, while darker areas are less. Numerous patterns are visible, like the continuous viewing zones as ovals in the lower-left and upper right, patterns from overlapping TESS FFIs, or the Kepler footprint shapes stamped along the ecliptic and in the original Kepler field in the upper-right.

A grid of 16 images, 4x4, showing the sky background only for specific missions to get a sense of where in the sky and how much of it each mission observed to at least some depth.

Ever wondered what the "MAST Sky" looks like, from our ~6 PB of data spanning 3 decades...check this out! spacetelescope.github.io/mast-blog/ma...

Really fun project led by the very talented Julie Imig at MAST, showing mission coverage sky-projected! They make VERY good video backgrounds, btw. 🔭

NASA's new PUNCH mission is a constellation of 4 small satellites that collectively provide an unprecedented view of giant eruptions breaking free from the Sun.

This first-release video compresses about 6 days of observations. 🧪🔭

A section of the Cat’s Paw Nebula, a local star-forming region composed of gas, dust, and young stars. Four roughly circular areas are toward the center of the frame: a small oval toward the top left, a large circle in the top center, and two ovals at bottom left and right. Each circular area has a luminous blue glow, with the top center and bottom left areas the brightest. Brown-orange filaments of dust, which vary in density, surround these four bluish patches and stretch toward the frame’s edges. Small zones, such as to the left and right of the top-center blue circular area, appear darker and seemingly vacant of stars. Toward the center are small, fiery red clumps scattered among the brown dust. Many small, yellow-white stars are spread across the scene, some with eight-pointed diffraction spikes that are characteristic of Webb. A few larger blue-white stars with diffraction spikes are scattered throughout, mostly toward the top left and bottom right.

Hooray for three years of paw-sitively amazing #NASAWebb science! To celebrate, the telescope examined a singular “toe bean” of the Cat’s Paw Nebula, a massive star-forming region. Webb reveals gas, dust, and massive young stars: webbtelescope.pub/4khJK9T 🔭

This is what we are doing after Roman. But only if NASA science funding is kept at the levels we need. It takes decades to plan and build these missions, and it’s only possible through steady public support AND stable federal funding throughout the years.

The work our talented team does to ensure the public learns about discoveries made with NASA telescopes, and our place in the Universe, risks being lost without at least keeping NASA’s funding flat. The current budget plan removes almost all of it. If this matters to you, make sure your reps know.

I present the #astrocode Pyriod for interactive or scripted pre-whitening frequency analysis of astronomical time series data. See the demo of #stellarastro #TESS data analysis of a pulsating white dwarf star. Check it out at github.com/keatonb/Pyriod/.

Excited for #BlackSpaceWeek 2025! #BlackInAstro

A code block labeled "A Common Bug (in compiled extension modules)." The code shows an attempt to exit a calculation of a large array of random numbers, and then indicates that a Ctrl+C interrupt takes 3.5 seconds to return, rather than returning immediately as is probably the desired and expected behavior.

Have you ever started a Python process, realized that you made a mistake, immediately hit Ctrl+C to interrupt it and then waited a surprisingly long time to get the command line back?

This delay is caused by a bug in the compiled #Python extension.

Learn how to use our powerful cloud platforms at the AAS meeting in Alaska! We need more interested attendees! 🔭

NEW: Those undulations aren’t clouds—they’re Jupiter’s aurora as seen by #NASAWebb. Webb observed light from a particular molecule, represented in orange, and found that the planet’s aurora fluctuates on timescales of minutes or seconds: webbtelescope.pub/4kbsB20 🔭 🧪

Experience the Cosmic Cliffs like never before! #NASAWebb’s iconic image of dusty “mountains” and “valleys” is featured in a new 3D visualization from NASA’s Universe of Learning: webbtelescope.pub/4jRHIh9 🔭 🧪

We are working on resolving this.

For those attending the AAS in the summer, consider signing up to take our data workshop where you'll learn how to effectively use our cloud platforms to query for data, access catalogs, and create image cutouts! Very relevant for TESS and Roman astronomers in particular, but all are welcome!
