There Is Something "Very Wrong" With Our Understanding Of The Universe, Telescope Final Data ConfirmsA small portion of the CMB showing its characteristics red to blue pattern. This represent a temperature map of the universe and it looks like a map of a world filled with randomly distributed islands suroundes by a seas. Overlayed on this are littel lines represenitng the direction of polarization.

Hubble Tension Solved? Astronomers Race To Save Standard Model Of CosmologyThis image shows many overlapping objects at various distances. They include foreground stars, galaxies in a galaxy cluster, and distorted background galaxies behind the galaxy cluster. The background of space is black. Thousands of small galaxies appear across the image. Their colors vary. Some are shades of orange, others are white. Most appear as fuzzy ovals, but a few have distinctive spiral arms.
