Hubble Celebrates Turning 33 with NGC 1333

A vertical image with colors ranging from blue at the top to golden in the middle and red at the bottom. At the top, a bright blue star is illuminating surrounding clouds of gas, making the top third of the image appear blue. Below the bright star, a couple dozen fainter stars shine yellow. One of them has a fuzzy, golden arc to its left. At the center of the image, a brighter yellow star illuminates surrounding gas. It is partially obscured by dark streaks and clouds of dust, making it resemble the moon on a cloudy evening. The bottom of the image is noticeably darker than the rest, with the exception of a dramatic splash of red almost like a bug splat on a windshield. A handful of faint, red stars also appear there.

We're celebrating 33 years of Hubble observations today with the release of Hubble's observations of NGC 1333. Read on to find out more about this target, how it was observed, and how the data were processed into this years's anniversary image.
