i do not believe they are even remotely the same. there is no way that movement can be detected in a span of say ten years that is 1.5 billion light years away. unless they can physically show me 3 individual frames that differ showing the movement. And I doubt then i’d fully buy it! the colors you see are not temperatures or speeds. they are added for visual purposes to show the different galaxies...
I’ve followed these threads for years and mainly because the fake news/photos from APOD CONSTANTLY, i find it hard to believe ANYTHING out of the space agency anymore.
As I said, it has nothing to do with detecting movement, but what the Doppler shifting of its light tells you. This technology has been around for a long time. You may believe what you wish, however.
