1.5Tb of James Webb Space Telescope Data Dumped On The Internet - New Searchable Database

Arthur T Knackerbracket has processed the following story:

New imagery encompassing nearly 800,000 galaxies.

The Cosmic Evolution Survey (COSMOS) has just released the largest look ever into the deep universe." Even more importantly, it has made the data publicly available and accessible in an easily searchable format." Possibly the star attraction from this massive 1.5TB of James Webb Space Telescope (JWST) data is the interactive viewer, where you can gawp at stunning space imagery encompassing nearly 800,000 galaxies. At the same site, you can find the complete set of NIRCam and MIRI mosaics and tiles, plus a full photometric catalog.

The COSMOS-Web program is a NASA-backed project with the support of scientists from the University of California, Santa Barbara (UCSB), and Rochester Institute of Technology (RIT). With this significant data release, the public at large is getting access to the largest view deep into the universe they will have ever seen.

According to the press release announcement, the published survey maps 0.54 degrees of the sky, or about the area of three full moons," with the NIRCam (near infrared imaging), and a 0.2 square degree area with MIRI (mid-infrared imaging).

To help Joe Public make sense of this 1.5TB data deluge, COSMOS-Web has thoughtfully provided a full aperture and model-based photometric catalog. Using this reference, those interested can observe photometry, structural measurements, redshifts, and physical parameters for nearly 800,000 galaxies." More excitingly for amateur astrophysics enthusiasts, the researchers claim that the new JWST imaging, combined with previous COSMOS data, opens many unexplored scientific avenues."

Before you head on over to the linked resources, it might be useful to familiarize yourself with some of the terms and units used by COSMOS-Web. If we want to look more closely at the JWST NIRCam mosaics, for example, you will see that the newly surveyed area is mapped into 20 zones with reference codes. Each of the mosaics is available in four NIRCam filters (F115W, F150W, F277W, F444W). In terms of scale, mosaics are available in both 30mas and 60mas. Mas' is short for milliarcseconds, a unit of angular measurement commonly used in astronomy.
