“James Webb’s new footage is phenomenal. They surprise even researchers who have been studying the same galaxies for decades. They tell the story of the star formation cycle,” said Janice Lee, a research associate at the Strategic Initiatives Project at the Space Telescope Science Institute in Baltimore.

The telescope’s NIRCam (Near Infrared Camera) is said to have captured millions of stars in these images. Some stars are located along entire “spiral arms”, while others are tightly packed together in star clusters.

The telescope’s data collected by MIRI (Mid Infrared Instrument) illuminates the glowing dust, showing us exactly where it is located around and among stars. These data also show stars that have not yet fully formed.

“We can find the youngest, most massive stars in the galaxies here,” said Eric Rosolowski, a professor of physics at the University of Alberta in Edmonton, Canada.

Data collected by astronomers shows that galaxies are growing from the inside out; Star formation begins in the cores of galaxies. The further a star is from the galactic nucleus, the more likely it is to be young.
