Sandstrom team reveal stunning JWST nearby galaxy images
Prof. Sandstrom, UC San Diego Postdoc Scholar Jessica Sutter, and former UC San Diego Postdocotral Scholar Jeremy Chastenet released their latest James Webb Space Telescope (JWST) findings on dust in the insterstellar medium in nearby galaxies. The latest findings show the critical importance of studying polycyclic aromatic hydrocarbons (PAHs) and inferring the astrophysics of star formation and the ISM. Picture: A side-by-side comparison of NGC 628 (Phantom Galaxy) images taken from the Spitzer Space Telescope (l) and JWST (r) show a remarkable increase in clarity and detail.

ASTRONOMERS SPOT A TINY BINARY SYSTEM
Prof. Burgasser and UC San Diego Ph.D. alum Chih-Chun “Dino” (now postdoc at Northwestern University) published a stunning paper on one of the most tiniest binary stars. The discovery was announed at the 241stAmerican Astronomical Society Meeting. The binary is a pair of ultracool dwarfs that orbit each other in just 20.5 hours. The star system is the lowest-mass binary ever found, and this discovery launches new questions about how common these tight cool binaries exist.
