It’s a combination image consisting of infrared shots taken from the telescope’s MIRI (MidInfrared Instrument) and NIRCam (NearInfrared Camera) sensors.
What those sensors captured is a galaxy in the Virgo constellation about 20 million lightyears from Earth, and because the JWST can see through the dust and gas that surrounds stars as they’re born, the instrument is particularly suited to producing images that show the process of star formation.
Looking at the two individual images that make up the composite reveals different layers of the galaxy.
The second image, taken from the NIRCam, put the focus on a huge swath of stars in the foreground.
The composite, meanwhile, shows both the enormous amount of stars in the region as well as the highlights of the stars that have just been “born.”
