COSMOS-Web (PID: 1727) is a 255 hour wide-field Cycle 1 JWST treasury program that maps a contiguous 0.6 deg2 area with deep NIRCam imaging in 4 filters (F115W, F150W, F277W, and F444W) and a non-contiguous 0.2 deg2 area with MIRI in parallel.

August 29, 2025 - When NASA’s James Webb Space Telescope begins science operations in 2022, one of its first tasks will be an ambitious program to map the earliest structures in the universe. Called COSMOS-Webb, this wide and deep survey of half-a-million galaxies ...

June 12, 2025 - Compiled from more than 10,000 images of COSMOS-Web – the largest observing program of James Webb Space Telescope's first year in orbit – the map covers about three times as much space as the moon takes up when viewed from Earth.

March 8, 2023 - We present the survey design, implementation, and outlook for COSMOS-Web, a 255 hour treasury program conducted by the James Webb Space Telescope in its first cycle of observations. COSMOS-Web is a contiguous 0.54 deg$^2$ NIRCam imaging survey in four filters (F115W, F150W, F277W, and F444W) that will reach 5$σ$ point source depths ranging $\sim$27.5-28.2 magnitudes.

June 5, 2025 - COSMOS-Web provides the largest view deep into the universe ever, and now all of its data are available publicly in an easily searchable format. COSMOS-Web was the largest General Observer program selected for Cycle 1 of the James Webb Space ...

COSMOS-Web is a 255-hour Webb Treasury programme that maps 0.54 square degrees (a little more than two-and-a-half times the area covered by three full moons) of the COSMOS field using four NIRCam filters.

June 11, 2025 - Astronomers using data from NASA’s James Webb Space Telescope have identified dozens of small galaxies that played a starring role in a cosmic makeover that transformed the early universe into the one we know today.

May 5, 2025 - The COSMOS-Web survey (renamed from COSMOS-Webb, as it will survey a portion of the cosmic web) will map 0.6 square degrees of the sky — about the area of three full Moons — using the James Webb Space Telescope’s Near Infrared Camera (NIRCam) ...

COSMOS-Web is the largest contiguous area survey to be mapped by the James Webb Space Telescope (JWST) in Cycle 1, covering a contiguous 0.6 deg2 area with deep NIRCam imaging in four filters (F115W, F150W, F277W, and F444W) and a total 0.2 ...

June 6, 2025 - COSMOS-Web provides the most expansive and deepest observations of the universe to date. Now, the team behind this work - which includes several members from The University of Texas at Austin - has released the data and images associated with its full survey, all processed and ready for analysis (see images, specifically, here).

June 5, 2025 - Called the COSMOS-Web field, the project, with data collected by the James Webb Space Telescope (JWST), consists of all the imaging and a catalog of nearly 800,000 galaxies spanning nearly all of cosmic time.

June 5, 2025 - COSMOS-Web was the largest General Observer program selected for Cycle 1 of the James Webb Space Telescope (JWST). The survey mapped 0.54 square degrees of the sky (about the area of three full moons) with the Near Infrared Camera (NIRCam) and ...

Over the course of 208.6 observing hours, the COSMOS-Webb program will conduct an ambitious survey of half a million galaxies with multi-band, high-resolution near infrared imaging and an unprecedented 32,000 galaxies in mid infrared.

August 21, 2023 - We present the survey design, ... cycle of observations. COSMOS-Web is a contiguous 0.54 deg2 NIRCam imaging survey in four filters (F115W, F150W, F277W, and F444W) that will reach 5σ point-source depths ranging ∼27.5–28.2 mag....

October 14, 2024 - The first images from the James Webb Space Telescope (JWST) have electrified the world — and astonished veteran scientists with the wealth of information they reveal. In 'Infinite Cosmos,' National Geographic tells the 20-year saga of the telescope's development and the feats of science needed to send it into orbit around the sun, a million miles from Earth.

COSMOS-Webb probes an area 3 times the area of the full Moon to scan a wide area of space for rare, massive galaxies, while WDEEP drills 15 to 20 times fainter in a single narrow region, sensitive to the smallest, earliest galaxies.

May 25, 2023 - Webb studies every phase in the history of our Universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

March 18, 2025 - COSMOS-Web aims to map the earliest structures of the universe and will create a wide and deep survey of up to 1 million galaxies.
