Stsci astrometry4/18/2023 ![]() From this, the ERO Committee selected a superset of targets based on existing data, particularly color images taken by the Hubbleand Spitzer Space Telescopes. In the first section of the paper, the authors state how these targets were selected in 2017 by the ERO Committee based on solicitations from the American Astronomical Society (AAS) and the JWST Science Working Group (SWG). The ERO describes how these targets were selected, which of Webb’s instruments were used to study them, and what they revealed. The paper that describes the ERO was authored by researchers from the STScI, the Association of Universities for Research in Astronomy (AURA), and the Department of Physics & Astronomy at John Hopkins University.Īs noted in a previous article (concurrent with the release), the first observations from the Webb mission included a deep field image of the SMACS J0723.3-7327 galaxy cluster and distant lensed galaxies, the merging galaxy group known as Stephan’s Quintet, the Carina Nebula (NGC 3324), the Southern Ring planetary nebula (NGC 3132), and spectra obtained from the transiting hot Jupiter WASP 96b. These products were chosen by the ERO Selection Committee, an international body formed in 2016 composed of members from NASA, the Canadian Space Agency (CSA), and the European Space Agency (ESA), with support provided by the Space Telescope Science Institute (STScI). ![]() The EROs is a set of public outreach products created to mark the end of JWST’s commissioning and the beginning of science operations. Less than a month after their release, a paper titled “ The JWST Early Release Observations” has been made available that describes the observations and the scientific process that went into making them. ![]() These included images and spectra obtained after Webb’s commissioning phase, which included the most-detailed views of galaxy clusters, gravitational lenses, nebulae, merging galaxies, and spectra from an exoplanet’s atmosphere. On July 12th, 2022, NASA and its partner agencies released the first James Webb Space Telescope (JWST) observations to the public.
