Explanation: Gravitational lensing by the galaxy cluster MACS0647 -- in which the massive foreground cluster distorts and lenses the light emitted by distant background galaxies along the line of sight — is on vivid display here in this recent multi-color infrared image from the James Webb Space Telescope (JWST). In particular, the background source MACS0647-JD is seen to be lensed three times by the cluster. When first discovered with the Hubble Space Telescope, MACS0647-JD was observed as an amorphous blob. With Webb though, this single source is revealed to be a pair or small group of galaxies. The colors of the MACS0647-JD objects are different as well -- indicating differences potentially in the age or dust content of these galaxies. These new images provide rare examples of galaxies in an era only a few 100 million years after the Big Bang.

More proof that he was right.

I am amazed by the Hubble extra deep field photographs that hone in on a minute expanse of sky with only a couple of foreground stars from our galaxy in view. In those photos, every single point or smudge of light, white or reddish or yellow are galaxies themselves.

A pile of presupposing going on, saying that they’re looking at the old part of the universe. So far we haven’t found the middle or the edges. All we know is that everything is moving away from everything.
