NASA's Webb Depicts Staggering Structure in 19 Nearby Spiral Galaxies

January 29, 2024 10:00AM (EST)Release ID: 2024-105
Several Webb images of face-on spiral galaxies are combined in a mosaic, some within squares, and others horizontal or vertical rectangles. Galaxies' spiral arms appear in shades of orange, and many of their centers have light blue hazes.

Summary

A new treasure trove of Webb images has arrived! Near- and mid-infrared images show off every facet of these face-on spiral galaxies.

Humanity has spent centuries mapping Earth’s features – and we frequently repeat the process by using more advanced instruments. When we combine the data, we get a more complete understanding of our planet.

Now, look outward into space. Astronomers have observed nearby, face-on spiral galaxies for decades. Both space- and ground-based telescopes have contributed to a cache of data in wavelengths from radio to ultraviolet light. Astronomers have long planned to use NASA’s James Webb Space Telescope to obtain the highest resolution near- and mid-infrared images ever taken of these galaxies, and today they are publicly available.

Everyone can explore Webb’s newest set of exquisite images, which show stars, gas, and dust on small scales beyond our own galaxy. Teams of researchers are studying these images to uncover the origins of these intricate structures. The research community’s collective analysis will ultimately inform theorists’ simulations, and advance our understanding of star formation and the evolution of spiral galaxies.
