The early peas were found in the James Webb Space Telescope's deepest and sharpest infrared image of the distant universe yet seen, which imaged thousands of galaxies in and behind a cluster known as SMACS 0723. The cluster’s mass makes it a gravitational lens, which both magnifies and distorts the appearance of background galaxies. Astronomers zeroed in on a trio of faint, compact infrared objects whose properites resemble green peas.

Green pea galaxies were discovered and named in 2009 by volunteers taking part in Galaxy Zoo, a project where citizen scientists help classify galaxies in images, starting with those from the Sloan Digital Sky Survey. They stood out as small, round, unresolved dots with a distinctly green shade, a consequence of both the colors assigned to different filters in the survey’s composite images and a property of the galaxies themselves. A larger-than-usual fraction of their light comes from hot gas, which emits light in discrete colors as opposed to a continuous rainbow-like spectrum.

Detailed chemical fingerprints of these early galaxies show that they include what might be the most primitive galaxy identified so far, with just 2% of the oxygen content of a galaxy like our own. They allow astronomers to connect these galaxies from the dawn of the universe to similar ones nearby, which can be studied in much greater detail.", "items": [], "extra_data": {} }, { "id": 313239, "url": "https://svs.gsfc.nasa.gov/14269/#media_group_313239", "widget": "Single image", "title": "", "caption": "", "description": "Same as above, but the galaxies are labeled with their identifications and the green circles have been removed.

The galaxy, which formed as a result of a collision between a large spiral galaxy and another smaller galaxy, not only retained a lot of its spiral character, but has also experienced massive changes throughout its structure. Webb’s high-precision instruments resolved individual stars and star-forming regions within the Cartwheel, and revealed the behavior of the black hole within its galactic center. These new details provide a renewed understanding of a galaxy in the midst of a slow transformation. || cartwheel_348_print.jpg (1024x576) [152.0 KB] || cartwheel_348.png (3840x2160) [9.1 MB] || ", "release_date": "2022-08-09T00:00:00-04:00", "update_date": "2024-06-03T00:10:38.431192-04:00", "main_image": { "id": 370444, "url": "https://svs.gsfc.nasa.gov/vis/a030000/a031100/a031186/eta-carina-cliffs_00468_print.jpg", "filename": "eta-carina-cliffs_00468_print.jpg", "media_type": "Image", "alt_text": "The seemingly three-dimensional “Cosmic Cliffs” showcases Webb’s capabilities to peer through obscuring dust and shed new light on how stars form. Webb reveals emerging stellar nurseries and individual stars that are completely hidden in visible-light pictures. This landscape of “mountains” and “valleys” is actually the edge of a nearby stellar nursery called NGC 3324 at the northwest corner of the Carina Nebula. So-called mountains — some towering about 7 light-years high — are speckled with glittering, young stars imaged in infrared light. A cavernous area has been carved from the nebula by the intense ultraviolet radiation and stellar winds from extremely massive, hot, young stars located above the area shown in this image. The blistering, ultraviolet radiation from these stars is sculpting the nebula’s wall by slowly eroding it away. Dramatic pillars rise above the glowing wall of gas, resisting this radiation. The “steam” that appears to rise from the celestial “mountains” is actually hot, ionized gas and hot dust streaming away from the nebula due to the relentless radiation. Objects in the earliest, rapid phases of star formation are difficult to capture, but Webb’s extreme sensitivity, spatial resolution and imaging capability can chronicle these elusive events.", "width": 1024, "height": 576, "pixels": 589824 } } ], "sources": [], "products": [ { "id": 14345, "url": "https://svs.gsfc.nasa.gov/14345/", "page_type": "Produced Video", "title": "A Sea of Data with PACE", "description": "Music: \"Natural Time Cycles,\" \"Anywhere But Here,\" \"Discovering New Things,\" Universal Production MusicComplete transcript available.Video Descriptions available. || PACE_MissionOverview_thumb.png (1280x720) [882.6 KB] || PACE_MissionOverview_thumb_print.jpg (1024x576) [141.5 KB] || PACE_MissionOverview_thumb_searchweb.png (320x180) [77.5 KB] || PACE_MissionOverview_thumb_thm.png (80x40) [6.4 KB] || PACE_SeasofData_YT.mp4 (1920x1080) [433.1 MB] || PACE_SeasofData_prores.mov (1920x1080) [3.6 GB] || PACE_SeasofData_prores.webm (1920x1080) [29.4 MB] || PACE_MissionOverview.en_US.srt [5.6 KB] || PACE_MissionOverview.en_US.vtt [5.4 KB] || PACE_SeasofData_EIC_Captions_v1.mov (7680x2160) [2.1 GB] || PACE_SeasofData_EIC_Captions_v2.mov (7680x2160) [2.3 GB] || PACE_SeasofData_EIC_Captions_v3.mov (7680x2160) [70.9 MB] || ", "release_date": "2023-05-10T00:00:00-04:00", "update_date": "2024-02-03T07:49:21.711951-05:00", "main_image": { "id": 855170, "url": "https://svs.gsfc.nasa.gov/vis/a010000/a014300/a014345/PACE_MissionOverview_thumb.png", "filename": "PACE_MissionOverview_thumb.png", "media_type": "Image", "alt_text": "Music: \"Natural Time Cycles,\" \"Anywhere But Here,\" \"Discovering New Things,\" Universal Production MusicComplete transcript available.Video Descriptions available.", "width": 1280, "height": 720, "pixels": 921600 } } ], "newer_versions": [], "older_versions": [], "alternate_versions": [] }
