Webb’s First Deep Field, This image of galaxy cluster #SMACS0723 is overflowing with detail as it appeared 4.6 billion years ago.
Thousands of galaxies {Most appear as fuzzy ovals, but a few have distinct spiral arms} – including the faintest objects ever observed in the infrared – have appeared in Webb’s view for the first time. This slice of the vast universe is approximately the size of a grain of sand held at arm’s length by someone on the ground.

A side by side comparison of the #JamesWebbSpaceTelescope’s First Deep Field (MIRI and NIRCam).
#SMACS0723 is a cluster of #Galaxies located in the southern #Constellation #Volans that contains thousands of galaxies, including some of the faintest objects ever observed in infrared light. When viewed in mid-infrared light (L), the region appears with a range of new colors compared to the near-infrared image (R).

Revisiting the first image of the #JamesWebbSpaceTelescope.
The image provides an unparalleled level of detail of the galaxy cluster #SMACS0723, showing it as it appeared 4.6 billion years ago. SMACS 0723 is a cluster of galaxies located in the southern constellation #Volans and has not been extensively studied in the past.
