The James Webb Space Telescope is ready to go, which will expand our horizons by allowing us to look deeper into space in greater detail than ever before. This week, it began sending its first test images to Earth after its mirrors finished adjusting. Behind the image he took by focusing on a star named 2MASS J17554042+6551277 2,000 light-years away, galaxies millions of light-years away are also visible.
Astronomers who want to view the state of the telescope’s mirrors during the tests also take images taken from the reverse side. In other words, this telescope has the ability to take “selfies”.
The latest selfie, which you can see below, was taken to see if its mirror, which consists of 18 gold-plated hexagonal pieces, is fully adjusted. From the image it seems that everything is fine.
