SMACS-0723 viewed by the James Webb Space Telescope in infrared light.


This image shows the SMACS-0723 cluster. SMACS-0723 was imaged by the James Webb Space Telescope and presented to the public for the first time by President Joe Biden on the 12/07/22. There are thousands of galaxies scattered around the image. The light of some of these galaxies has been travelling for some 13 billion years! I study these images to better understand this ancient light and the galaxies that produced it.
