Have you seen this video of the Comet 3I/ATLAS of observations from TESS? science.nasa.gov/blogs/3iatla... Data available at MAST.
New job opportunity at @stsci.edu: Senior Astronomical Data Scientist for data analysis tools, working closely with my team and me.
This role is very similar to mine. If you have questions, I'm happy to answer them. 🧪🔭
Such great work by the community with all that TESS data.
May I recommend this paper if you are interested in publication rates by mission. arxiv.org/abs/2512.18101
It also links to previews of the IUE spectra. archive.stsci.edu/cgi-bin/mast...
For example, here is a search for IUE observations of one of my favorite white dwarf stars, G29-38. mast.stsci.edu/search/ui/#/...
Dozens of papers are still published every year using this mission that ended back in 1996.
Aren't public astronomical archives great!
For those astronomers who still use the International Ultraviolet Explorer (IUE) data, a NASA+ESA mission that flew for 19 years starting in 1978, there is a new IUE specific search form and API at @mast-news.bsky.social for you to find IUE data

SPARCS and Pandora launched together!!! Two small sats I’m very excited about, and thrilled for my friends and colleagues who have worked on them! 🔭
To learn more about Pandora science, check out our website here!
pandorasat.com
It's happening!!! Pandora is going to space in just over 16 hours (if all goes well). Pandora is going to help us study exoplanet atmospheres, even when their host stars are misbehaving. I am headed up to Vandenberg to watch the launch shortly, and will make a thread about the mission/launch here!
Come work at STScI!

Come work at STScI!
It's finally here. Pandora is launching this weekend! svs.gsfc.nasa.gov/14945/.
Led by Elisa Quintana and Jesse Dotson (I sit on the science team with many amazing scientists), it has been such fun watching this telescope go from proposal to launch. Get ready to observe some stars and exoplanets!
Packed splinter session at #AAS247 for the announcement of The Eric and Wendy Schmidt Observatory System—a modular, rapid-response network of four novel observatories designed to democratize access to the cosmos.

I messed up the link to the paper, here is a better link, now without the extra period. arxiv.org/pdf/2512.08191
Érika thank you for being part of the team.

It was my first quiet night in over a month, thanks for reminding me to post something.
It was a small search, only 4 WDs. And we weren't gifted with a resolved planet this time. But that doesn't mean we shouldn't keep looking. We showed that JWST allows us to find nearby giant planets around WDs. We just have to look twice to rule-out those pesky galaxies lurking in the background.
We were really expecting to find planets with this tiny survey of 4 WDs and we still have 2 unresolved candidates left to confirm.
For resolved planets we were able to rule-out planets as small as half the mass of Jupiter out to hundreds of au.
However, earlier @johndebes.bsky.social showed that two of the white dwarfs are too bright in the mid infrared, consistent with a 1.4 Jupiter-mass, unresolved planet. For one of those stars, our data show the excess also moves with the WD. So it is bound to the WD and could be a planet.
Here is the key image from the paper. The red cross marks the candidate planet and the green triangle is on top of the white dwarf star. The WD moves several pixels, the red dots do not. Those red dots are likely distant, background galaxies.
Sadly, in a paper by @fergalm.bsky.social, @johndebes.bsky.social and others, arxiv.org/pdf/2512.081.... JWST shows that those two spots do not move across the sky like the white dwarf star. The separation between the spot and the star (green triangle) change between the two observations. Boo!
If they are planets, they would be bound to the white dwarf star and would move across the sky in the same way that the nearby white dwarf does. So we asked for second observations of the white dwarf to see if the spots moved too.
Remember those red spots next to two white dwarf stars that looked like possible planets in JWST images that we found?
We just had a paper accepted that continues to tell the story.
