It also recently saw the first particles of light making their way through the entire telescope.
During the initial process, the images remain blurred and scientists will use them slowly to fine-tune the telescope.
The observatory is expected to be ready for science by summer this year.
The agency said James Webb's Near Infrared Camera (NIRCam) detected the first photons of starlight that travelled through the telescope.
A team of engineers and scientists will now use the data taken with NIRCam to gradually align the telescope's 18 mirrors to form a fresh lens, NASA added.
