Lost Sisters Found: TESS and Gaia Reveal a Dissolving Pleiades Complex
Most 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...

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.

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.

One day the universe will contain only dark energy and JWST proposals.
STScI received a total of 2,935 #JWST proposals requesting almost 101,751 hours of observing time for GO, Survey, Pure Parallel, Archival Research, Target of Opportunity, and Joint programs, with an oversubscription rate of 13:1. Get the details: ow.ly/Fmiq50Xqy9Q

This is so cool. Siblings of the Pleiades strewn over the entire sky. Within some of the oldest written languages in the world, from Sumerian to Eblaite to Akkadadian and Hebrew, the name for Pleiades has etymological links to the word "family," and now that family is much bigger.

Brief life update: On Monday I resigned from my appointment at Lowell Observatory. I wish my remaining friends and colleagues the best of luckin their endeavors in increasing new visitor center visitation, and continuing to pursue world-class research in the face of having ended tenure today.

Remember, if tenure were gone tomorrow, Loeb would certainly be untouched (he brings in tons of private money). The people criticizing him, that’s a bit less clear.
Loeb is an example of why we need tenure, not a reason to get rid of it.
