seven panel figure showing different JWST transits of TOI-3884 b with a persistent spot-crossing event. TOI-3884 b orbits the pole of a small M dwarf star. the shape of the spot-crossing event changes slightly between each transit. each subpanel has a graphical representation of what the spot looks like during each transit.

really exciting work lead by Catriona Murray! TOI-3884 b is a planet on a polar orbit around an M dwarf. The transit has a persistent starspot crossing event. Using JWST, we measured the properties of the starspot and the Prot of the star 👀 arxiv.org/abs/2603.15414

New research on flares from a hot-tempered star could inform search for habitable planets A new study takes a close look at TRAPPIST-1, a little star roughly 40 light-years from our sun that hosts seven Earth-sized planets.

1/ It's press day!🔭🧪 We apply a grid of time-dependent physical models to explain TRAPPIST-1 flares, predicting the X-ray & UV flux driving escape and photochemistry in planetary atmospheres, and correcting flare contamination in transit spectroscopy down to ~60 ppm:

The atomic spectral lines in this app come from the NIST atomic spectroscopy group, which has provided the world with spectroscopic measurements for 120 years.

Today we got word that the federal government is laying off the entire group. 🔭🧪

Yeah, that's what I did, and so far, so good

Anaconda | A Faster Solver for Conda: Libmamba conda 22.11 update: The libmamba solver's experimental flag has been removed. To use the new solver, update conda in your base environment: conda update -n base conda To install and set the new solver...

Have you tried the libmamba solver? It's definitely sped things up for me.

Happy International Day of Women in Science. The National Science Foundation’s list of flagged words includes both “Women” and “Female.”

Dr. David Ciardi, Deputy Director of NASA Exoplanet Science Institute (NExScI), poses with Dr. Catherine Clark, NExScI's Scientific Outreach Coordinator, in front of a Caltech speaker's podium on the first day of the Know Thy Star, Know Thy Planet 2 conference held Feb. 3-7, 2025 on the Caltech campus.

Know Thy Star, Know Thy Planet 2 kicks off today! 💫🤩✨

A follow-on to 2017's successful Know Thy Star meeting, #KnowThyStar2 welcomes almost 200 registrants to
Caltech for some stellar discussion on exoplanet science.

Talks will be posted to YouTube!

Please consider donating to some gofundmes for some friends and colleagues that work at NASA JPL that lost everything in the Eaton Fire in Altadena. I'm advertising a few that I know best who have been really wonderful people to work with my past 8 years on lab.

Donate to Supporting Jenn & Sam after the Eaton Fire, organized by Jenn Burt Hi friends, As many of you already know, the wildfires that tore through Alta… Jenn Burt needs your support for Supporting Jenn & Sam after the Eaton Fire
