NGC 1333 IRAS 2A Archives

Overview of the ALMA spectra (the continuum spectral window from 333.78 to 335.65 GHz; top panel) and JWST/MIRIMRS spectra (bottom panel) of NGC 1333 IRAS 2A and B1-c. The JWST spectrum of IRAS 2A between 8.85 and 11.7 µm was binned by a factor of 10 for better visualization. In the bottom panel, the fingerprint ranges of COM ices between 6.8 and 8.8 µm are highlight in orange. Important emission lines in the ALMA spectra and absorption bands in the JWST spectra are labelled in each panel. -- astro-ph.GA

JOYS+: Link Between Ice And Gas Of Complex Organic Molecules. Comparing JWST and ALMA Data of Two Low-mass Protostars

by Keith CowingJuly 31, 2024July 31, 2024

A rich inventory of complex organic molecules (COMs) has been observed in high abundances in the gas phase toward Class 0 protostars. These molecules are suggested to be formed in […]

An international team of scientists using the NASA/ESA/CSA James Webb Space Telescope has identified a wealth of complex, carbon-containing (organic) molecules surrounding two protostars. This graphic shows the spectrum of one of the two protostars, IRAS 2A. It includes the fingerprints of acetaldehyde, ethanol, methylformate, and likely acetic acid, in the solid phase. These and other molecules detected there by Webb represent key ingredients for making potentially habitable worlds. -- ESA

Webb Telescope Finds A Wide Variety of Organic Molecules Surrounding Early-stage Protostars

by Keith CowingMarch 24, 2024March 24, 2024

An international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope have discovered a variety of molecules, ranging from relatively simple ones like methane to complex compounds like acetic […]
