Bright stars stand out in Webb images with their eight sharply defined diffraction spikes. In the linked infographic and transcript, the science behind Webb's diffraction spikes is explained (credit: STScI).
Images don't come down from Webb in the beautiful full color renderings you see on this website and elsewhere. Someone has to translate the raw black and white image data into the color, especially since Webb collects light that falls outside of human vision. That’s where people like Joe DePasquale and Alyssa Pagan of the Space Telescope Science Institute come in. Learn how they makes choices about color and other aspects of space images.

JWST science observations are nominally scheduled in weekly increments. Planned schedules will be posted as they are made available. Since the schedules do not take into account unforeseen events, including some target of opportunity observations, it is possible that the actual executed observations will differ from those planned.
