The galaxy cluster appears hotter and more mature than it should for its young age, challenging what we think we know about how these cities of galaxies form.

Could it be that the nature of the universe is tricking us, merely because of our location? The ongoing “Hubble tension” the intransigent discrepancy between the universe’s local and cosmic expansion ...

The galaxies highlighted in this James Webb Space Telescope image have been confirmed to be at a distance that astronomers refer to as redshift 7.9, which correlates to 650 million years after the Big ...
