James Webb Space Telescope Near-infrared Camera (JWST NIRCam) false colour image of IRAS07251-0248, made by combining exposures with the 2 mm (Blue), 2.77 mm (Green) and 3.56 mm (Red) wide filters on NIRCam. Data are part of the observations carried out under JWST GO Programme ID 3368 (P.I. L. Armus). Calibrated data were obtained from the Mikulski Archive for Space Telescopes at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under NASA contract NAS 5-03127 for JWST.

Transmission spectra of solid methanol and its five deuterated isotopologues at 10 K. The region between 650 to 590 cm−1 (15.4 to 16.9 µm), affected by increased noise from the beamsplitter, has been removed. The main CH3OH vibrational modes are indicated at the top. Spectra are vertically offset for clarity. -- astro-ph.GA
