👀 very exciting!

The very first science data taken with #JWST were images of the globular cluster M92. There's a lot of exciting science we can (& will!) do with these images, but they also provide a great opportunity to test the calibration of the NIRCam instrument: arxiv.org/abs/2209.03348 [1/]

We are safe and remain vigilant as 🌋#MaunaLoa continues to erupt. Activity started last night, a first since 1984! Lava is flowing to the NE flank but no threat to residents right now. Our staff shot these fire & ice photos of the awakening volcano. Stay safe everyone!

😲 wow!!

Good people squad goals. #UVgalaxies2023

Here it is: NASA Webb Telescope’s one-year anniversary image. Called Rho Ophiuchi, this area shows about 50 young stars in a cocoon of gas and dust. At 390 light-years away, it's the closest star-forming region to Earth: go.nasa.gov/3rqX8Tl Webb continues to #UnfoldTheUniverse.

Superluminous supernovae, black hole mergers, and many more astrophysical puzzles are connected to massive stars at subsolar metallicities, which we investigate in the X-Shooting ULLYSES collaboration. Paper I has officially been published today: aanda.org/articles/aa/fu…

STScI has appointed Dr. Kristen McQuinn as its #NASARoman mission head. Dr. McQuinn will be responsible for the continued development and operations of the Roman Science Operations Center at STScI. Launch is currently planned for late 2026: bit.ly/3rcQQqv

Had an awesome time at Astronomy on Tap ATX #AoTATX75 tonight - thanks to the organizers and to everyone who came out!

Come join our new A&A department at UCSD and work with me on JWST observations of nearby galaxies!! Postdoc job ad now up on the AAS Register: jobregister.aas.org/ad/a61d3c64

Just so folks know -- the process for community input to NASA is the Astrophysics Program Advisory Committee. The next meeting is March 20/21, 2024 cor.gsfc.nasa.gov/news/2024/27_A…

And in the second Merian 🦋 paper out today: Princeton student Abby Mintz develops methods to turn medium-band imaging into Hα maps, and shows that low-mass starbursts tend to be more compact than their more massive counterparts. Read the paper here! arxiv.org/abs/2410.01886

Awesome news!! Congrats Roohi! 🎉
