PIA23123: A Field of Galaxies Seen by Spitzer and Hubble
<p>GREATS survey (GOODS Re-ionization Era wide-Area Treasury from Spitzer)<sup id="cite_ref-SA-20190509_1-0" class="reference"><a href="#cite_note-SA-20190509-1">[1]</a></sup><sup id="cite_ref-MNRAS-20190404_2-0" class="reference"><a href="#cite_note-MNRAS-20190404-2">[2]</a></sup></p><p>This deep-field view of the sky, taken by NASA's Spitzer Space Telescope, is dominated by galaxies - including some very faint, very distant ones - circled in red. The bottom right inset shows one of those distant galaxies, made visible thanks to a long-duration observation by Spitzer. The wide-field view also includes data from NASA's Hubble Space Telescope. The Spitzer observations came from the GREATS survey, short for GOODS Re-ionization Era wide-Area Treasury from Spitzer. GOODS is itself an acronym: Great Observatories Origins Deep Survey.
