Another #AAS247 🔭 in the books = another wonderful, whirlwind of exciting astronomy happening and coming soon! 💨
From topics like Roman, Euclid, and SPHEREx, to NExScI, NED, IRSA, NITARP, Firefly, PRIMA, and SHERA — there was something for everyone. Thank you to all!

IPACer @aussiastronomer.bsky.social & team shared the SHERA Mission Concept at #AAS247 🦸♀️ 🔭
Searching for Habitable Exoplanets with Relative Astrometry (SHERA) will look for rocky planets in the habitable zones of Sun-like stars for the 1st time & potentially discover the nearest Earth-like planets!

We're thrilled to welcome @caltech.edu President-Elect Ray Jayawardhana!
As a grad student, Jayawardhana (a.k.a RayJay) attended the first Michelson Interferometry Summer School in 1999. Today, it lives on as NExScI's Sagan Summer Workshop—and both the workshop and RayJay are still going strong.🔭🚀
