About the image

The image shows us a never-seen-before
view of a galaxy cluster called SMACS 0723.
It covers a patch of this sky approximately the size of a grain of sand held at arm’s length.

Image reveals
earliest galaxies

The image by Webb telescope captured starlight from objects that formed only a few million years after the Big Bang. The starlight
is older than 13 billion years.

How was
the image taken?

The image was taken by Webb telescope’s Near-Infrared camera. Galaxy cluster SMACS 0723’s gravitational field magnified the light from galaxies behind it for a clearer view.

Webb telescope

The James Webb Space Telescope was launched in 2021 and it costs around $10bn. It is orbiting in the second Lagrange region. With JWST, we will see more of the unexplored universe.
