These 7 spotlighted galaxies are so far away, their light took ~13 billion years to reach us, via @NASAWebb, which was also used to measure their velocities (more than 2 million mph!). https://go.nasa.gov/3V5UEnZ #NASAExoplanets
NASAs James Webb Space Telescope has confirmed, for the first time, a protocluster of seven galaxies at a distance that astronomers refer to as redshift 7.9, or a mere 650 million years after the big bang.
