There are hints of what the first operational images will be.
According to NASA administrator Bill Nelson, the deepest image of our universe has ever been taken.
Nelson suggested that the image will show the earliest objects yet seen, while not specifying which early-universe objects or how old these targets are. He said that this is farther than humanity has ever looked before.

The Hubble Space Telescope's deep image fields show the formation of our universe as little as a few hundred million years after the Bigbang.
Nelson spoke at an event at the Space Telescope Science Institute. During the media event, NASA discussed the range of science the observatory will conduct early in its tenure, including solar system objects, exoplanets, the early universe and a range of targets in between.
One of the images coming that day will be the first spectrum of an exoplanet, according to Thomas Zurbuchen, who spoke at the same event. A planet's chemistry can be seen in the amount of light emitted at certain wavelength.
We'll look at the worlds that keep us awake at night and wonder if there's life somewhere else. Zurbuchen said it was a big deal. Webb is designed to look at large gas giant planets and won't be able to get enough information from rocky worlds that might host life as we know it.
The first images from the observatory will be released on July 12. NASA's website and social media channels will be used to broadcast the live event. The Canadian Space Agency is one of the events that certain partners have committed to.
After launching into space in December of 2021, the four scientific instruments will be ready for use.
The instruments' check-off list can be found on the NASA website. The Space Telescope Science Institute in Baltimore runs the operations for the first cycle of observations.
