In the event of a U.S. government shutdown, STScI will extend the James Webb Space Telescope Cycle 5 proposal submission deadline for affected scientists. Details: https://www.stsci.edu/contents/news/jwst/2025/jwst-cycle-5-deadline-extension-in-case-of-government-shutdown #NASAWebb 🔭 🧪 ☄️

Guarantee - all those vowels and their ordering is mighty suspicious 😆

Excited to share the 1st High-Level Science Product release from the Rocky Words DDT! Each RWDDT eclipse will result in HLSPs which you can use for preliminary science investigations or as a starting point for your own reduction/fit. Awesome work by Tyler Baines, Achrène Dyrek, and the RWDDT CIT
🪐🔭

Join us tomorrow (September 10) at 11:00 EDT to learn about What's New in JWST Cycle 5! Presenters will cover policy changes, tips on proposal writing, and updates to available tools.

Read the latest about JWST's Rocky Worlds Director's Discretionary Time program, including final targets and an upcoming information session: ow.ly/mgxA50WReQt

The Rocky Worlds DDT has published our final target list. Join us for an information session on September 15 to learn more about the 9 targeted planets and the goals of the program.

STScI is now accepting applications for the Giacconi Fellowship in astrophysics. Start date is Fall 2026 and funding is available for 3 years. More info here: www.stsci.edu/stsci-resear...

*mumbles in social anxiety* oh yeah, dancing, no panic necessary 🥲

“Our results confirm that there is no statistical significance for DMS or DMDS in K2-18 b's atmosphere. … we estimate that ~25 more MIRI transits would be needed for a 3-sigma rejection of a flat line relative to DMS/DMDS features ….” arxiv.org/abs/2505.13407

There does seem to be some spectrally-correlated noise in MIRI/LRS time-series spectra. The impact is reduced for larger bin sizes, and the bin sizes used for K2-18b seem largely reasonable to me at first glance. More details about LRS spectrally-correlated noise in Bell+2024 and Welbanks+2024.

For others that are curious, this happened around 2:44:20 from this recording: www.bbc.co.uk/sounds/play/...

Well stated caveats and discussion Chris, and sorry you were treated this way. Glad the BBC had you on as well!

Upcoming JWebbinar on Exoplanet Time Series Observations, special MIRI edition! The @spacetelescope.bsky.social #JWST MIRI team has some great transiting exoplanet experts (including @taylorbell275.bsky.social) and they will be presenting this JWebbinar - registration details below.

Hey, artists, in case you were wondering if your work matters: I'm a scientist working on climate change and biodiversity, and I would not be who I am today without The Lorax, The Secret of NIMH, Watership Down, The Last Unicorn, and The X-Files. I know I'm not alone. Thank you for all you do.

Literally moments away from being safely transported to Maryland on a big auto transport truck, our car got rear ended while stationary... Thankfully still drivable and en route to Maryland, but really not what we were hoping for today...

Proud to see the special collection of Transiting Exoplanet Community Early Release Science papers out (all open-access)! www.nature.com/collections/...

This has been such a whirlwind of effort over the last few years, with a great team - it's hard to even imagine the pre-JWST era now.

Excited to share that on Jan 27th I'll be starting at @spacetelescope.bsky.social as an ESA/AURA Astronomer on the JWST/MIRI team! Thrilled to be joining an amazing group of people where I'll spend 50% of my time on support work (including supporting the Rocky Worlds DDT 🪐) and 50% on research 🔭

Exoplaneteers! The leads of the @spacetelescope.bsky.social Rocky Worlds program with Hubble and JWST will be providing an update for the community on Jan 21st at 11 am Eastern Time. You're encouraged to submit your questions ahead of the event. More info here > www.stsci.edu/contents/new... 🔭

You inspired me to get one almost a year ago, and I've been really glad to have it in our apartment that lacks any air circulation. CO2 used to get crazy high back when my MIL was living in our living room and my partner and I were both working from home in our small bedroom

What was the verdict? Did you end up enjoying it in the end?

I know taking B12 also helped my mom to the point where she doesn't even need iron supplements

I take iron pills every other day (supposed to be more effective than daily) on an empty stomach - gradually increases my levels enough to support my vegan diet and quarterly blood donations

2028 for me!

Happy to announce v1.0 of Eureka! for JWST time-series observations, with bug patches and new features. We made several backwards-compatibility breaking changes to make the pipeline easier to use and easier to maintain. Please check out the new version github.com/kevin218/Eur... 🔭🪐
