Recently, Joe Biden, the US President presented the first full-color photograph of the James Webb Space Telescope that is not a test.
This image shows the galaxy cluster SMACS0723, also known as Webb’s First Deep Field. It took less than a full day to get. This image is the most detailed and sharpest infrared picture of the early universe.
For the first time, the telescope was able to see thousands of galaxies including some of the most faint objects in the infrared. This small piece of the vast universe is about the same size as a grain of sand that a human being on Earth holds at arm’s reach.
The telescope’s optics are not to blame for the curvature at the center of this image. This is a gravitational lensing phenomenon. It is caused by the presence in the center of the image of another cluster galaxies (it isn’t visible in the picture), which distorts light from SMACS0723 and visually brings the cluster closer. This is actually a natural telescope on a cosmic scale.
