In Opinion “We definitely have an attention problem, but it’s not just a function of the digital technology that pings and beeps and flashes and nudges us ever closer to despair,” write D. Graham Burnett, Alyssa Loh and Peter Schmidt. “It starts with the way we think about attention.”

These are shells of dust coming off a pair of tightly bound stars, newly imaged by #JWST. There is such beauty in the universe.

New paper from my group! Stars aren’t born alone—they form in massive associations. If we want to understand how stars and planetary systems form, we need to figure out where today’s clusters came from… and where all their long-lost siblings ended up. arxiv.org/abs/2511.07533

Lost Sisters Found: TESS and Gaia Reveal a Dissolving Pleiades ComplexMost star clusters dissolve into the Galaxy over tens to hundreds of millions of years after they form. While recent Gaia studies have honed our view of cluster dispersal, the exact chronology of whic...arxiv.org

My most important service to solar system planetary science was being a part of the Science Definition Team (SDT), nearly a decade ago, that made the science case for an NASA Ice Giants Orbiter and Entry Probe. Check out our 2017 document: arxiv.org/abs/2511.13946

🧪🔭⭐ #exoplanets #exoplanet #youngplanets New paper from our group and @madysonbarber.bsky.social today! We report a brand-new planet around a <50 Myr star—adding to a very small (but rapidly growing!) population of the youngest known transiting planets. Paper: arxiv.org/pdf/2511.10734

Yall check this out, it’s the top coolest thing I’ve seen in a while, closed form autodiffable representation of optical interferometry, enormously powerful. Yes!!

So exhausting..

Astronomy 🔭 and physics ⚛️ GRFP applications are due Nov 14! Only seniors and 1st-year grad students can apply now (no second years).

Today Sept 27, 2025. It marks a special mathematical date because the numerals of the date form perfect squares. Written as 09/27/2025, it becomes 9,272,025, which is the square of 3,045. When written in the European format 27/09/2025, it becomes 27,092,025, the square of 5,205.
