First Images From NASA’s Webb Space Telescope Coming Soon - NASA

NASA’s James Webb Space Telescope, a partnership with ESA (European Space Agency) and the Canadian Space Agency (CSA), will release its first full-color images and spectroscopic data on July 12, 2022. As the largest and most complex observatory ever launched into space, Webb has been going...

“As we near the end of preparing the observatory for science, we are on the precipice of an incredibly exciting period of discovery about our universe. The release of Webb’s first full-color images will offer a unique moment for us all to stop and marvel at a view humanity has never seen before,” said Eric Smith, Webb program scientist at NASA Headquarters in Washington. “These images will be the culmination of decades of dedication, talent, and dreams – but they will also be just the beginning.”

While we wait for the big reveal, we do know what Webb will focus on in its first year of operations, called Cycle 1. The agency has already published the list of planned investigations following a competition within the science community to determine the highest-priority work, a process that will repeat each year of the observatory's lifetime.

Micrometeoroid strikes are an unavoidable aspect of operating any spacecraft, which routinely sustain many impacts over the course of long and productive science missions in space. Between May 23 and 25, NASA’s James Webb Space Telescope sustained an impact to one of its primary mirror segments. After initial assessments, the team found the telescope is still performing at a level that exceeds all mission requirements despite a marginally detectable effect in the data.

When the first full-colour images are released, may I suggest whoever gets to post them does so in a new thread in News and Current Affairs
 
Some other key info from above article;

Another image will provide the public with something else they’ve never seen before (which James Webb is ideally suited to provide). This image will feature an exoplanet, as well as spectral data from its atmosphere obtained by its advanced suite of spectrographs.

Here's a test-related preview that's on NASA's Webb-blog this week, but note that it's far from the quality we'll see next week.

This Fine Guidance Sensor test image was acquired in parallel with NIRCam imaging of the star HD147980 over a period of eight days at the beginning of May. This engineering image represents a total of 32 hours of exposure time at several overlapping pointings of the Guider 2 channel. The observations were not optimized for detection of faint objects, but nevertheless the image captures extremely faint objects and is, for now, the deepest image of the infrared sky. The unfiltered wavelength response of the guider, from 0.6 to 5 micrometers, helps provide this extreme sensitivity. The image is mono-chromatic and is displayed in false color with white-yellow-orange-red representing the progression from brightest to dimmest. The bright star (at 9.3 magnitude) on the right hand edge is 2MASS 16235798+2826079. There are only a handful of stars in this image – distinguished by their diffraction spikes. The rest of the objects are thousands of faint galaxies, some in the nearby universe, but many, many more in the distant universe. Credit: NASA, CSA, and FGS team.

The blog reveals some other interesting facts as well.
1. Bright stars stand out with their six, long, sharply defined diffraction spikes – an effect due to Webb’s six-sided mirror segments.
2. This test pic is already considered, for a short period anyway, to be among the deepest images of the universe ever taken.

Prepare to have mind blown. This is incredibly exciting.
