A little over 23 years ago, I wrote my first paper on white dwarf planetary systems and not only am I fortunate enough to still be able to go looking for them with JWST, that little paper (which almost got rejected) hit 400 citations #astrosci #exoplanets

Countdown clock in @stewardobservatory.bsky.social for our NASA Pandora Space Telescope: T-60 days!! Our team is getting ready for the launch of this incredibly exciting mission to explore worlds beyond the Solar System! #exoplanets @uazresearch.bsky.social @uarizonalpl.bsky.social

Lammers and Winn “On the Exoplanet Yield of Gaia Astrometry” makes breathtaking predictions for the Gaia DR4 data release in December 2026 - around 7500 new exoplanets around nearby stars! It will be revolutionary… and indicate new nearby systems to be imaged… #astrodon #exoplanets ☄️

‘An Overview of Exocomets’ is a very comprehensive review led by Daniela Iglesias started at an @issibern.ch meeting. I worked on Figure 1 detailing comets around the Sun, Beta Pic and a white dwarf - I’m very proud of it, and it is available on @github.com: Exocomet systems #astrodon #exoplanet ☄

A little less than a year ago, a large team of cosmologists reported evidence that dark energy (which drives the acceleration of the expansion of the Universe) evolves over time. This made a huge splash but has also been viewed with healthy skepticism. Today they report that evidence has weakened. 🧪

Brilliant. I feel better now. 😄

We've collected 65 individual exoplanet atmosphere composition measurements to look for population-level trends 🔭 #exoplanets To do this, we had to create a toolkit to standardize between definitions of . We call it ExoComp. (Yes, that's a Star Trek reference 😀).

To make water, exoplanets might just need some pressure A reaction between hydrogen and magma at high pressure can produce water, which might explain evidence for ‘wet planets’ in places where water can’t condense. 🧪🔭 ☑️ www.nature.com/articles/d41... ☑️ www.nature.com/articles/s41...

I do like checking in on the K2-18b habitability saga every once in a while. Judging on this paper, it looks like the argument that everyone's favorite sub-Neptune could reflect enough sunlight to keep temperatures clement might not hold up.🔭🧪 doi.org/10.3847/1538...

Excellent Halloween display found this morning in the @haverfordcollege.bsky.social Astronomy Library. Skeleton is reading Stellar Structure by Chandrasekhar of course! :) 🔭🧪🎃

A clear trend is emerging in 2025: the reevaluation of 50-year-old studies has led to major revisions of the Mars Viking (1976), the Wow! Signal (1977), and Venus Pioneer (1978) results. 😲

It’s Halloween week and I haven’t seen any talk about our favorite spooky #exoplanets yet this year! Crowd-sourcing ideas for our exoplanet journal club this week — what’s your nomination for spookiest exoplanet? 👻
