Now done with exoplanets and moving to much larger scales with a great talk by @annanierenberg on measuring invisible small dark matter halos with Keck, JWST, and ELTs

Another annual physics faculty retreat in the books. Great discussions and concrete plans for our research and academic programs as well as for continuing to build community between undergrads, grads and faculty in the upcoming academic year.

What is one of the best parts of being a @UofCalifornia astronomer? Access to @UCObservatories including @keckobservatory! Thanks to everyone who made this trip possible. Special shoutout to @astronomeara and @richmatsuda for showing us around.
That feeling when you're seeing one of the 10 meter telescopes @keckobservatory.
We had an incredible visit with @ChancellorMunoz sharing the exciting science being done by @ucmerced at @UCObservatories, and opportunities for our campus.
With @sloebman, @MarjorieZatz

As the Sun sets in this #imageoftheweek, and its light scatters through Earth’s atmosphere, the Arizona sky at @KittPeakNatObs, a Program of @NSF’s @NOIRLabAstro, glows in wondrous shades of vivid color. noirlab.edu/public/images/io… Image: KPNO/NOIRLab/NSF/AURA/T. Slovinský.

The storm Sunday and Monday covered Mount Hamilton with snow, making the road dangerously icy. We expect the sunny weather today to melt most of the snow and icy. kron4.com/news/bay-area/vide…

UC Merced Professor Anna Nierenberg leads a team that has cooked up a clever way to use the James Webb Space Telescope to try to understand the fundamental nature of dark matter, that invisible stuff that makes up a quarter of the universe. ucm.edu/CyVUce via @NPR

If you weren't able to tune in live this AM, you can listen to the @CapRadioInsight interview I did this morning here on this link. The JWST segment starts around the 12 minute mark :)
