The James Webb Space Telescope has revealed several detailed images of a group of spiral galaxies, including the Messier 95 galaxy NGC 3351, which is a barred spiral galaxy. The images show a significant difference from old images taken by the previous Hubble Space Telescope of the same galaxies.
The James Webb Telescope relies on near and medium infrared rays to reveal the glowing dust and gases surrounding galaxies, which appear in shades of orange and red. In contrast, the Hubble Telescope captures visible and ultraviolet light coming from the galaxy, and dark areas indicate that dust has absorbed light from stars and prevented it from reaching us.
In the arms of the galaxy away from the center, the star formation process is active, and the mid-infrared rays show part of these active processes.
The Messier 95 galaxy is located in the constellation Leo, 33 million light-years away.
