The new record happened by accident.
Astronomers using the James Webb Space Telescope have spotted what they think may be the farthest galaxy ever seen — a distant red smudge 35 billion light-years away.
The new result, which is still preliminary and has yet to be confirmed by studying the spectra of the galaxy’s light, has already broken a previous provisional record set by the telescope just one week ago, when another team spotted GLASS-z13, a galaxy that existed 400 million years after the Big Bang. Light has a finite speed, so the farther it has traveled to reach us, the further back in time it originated.
Webb's extreme sensitivity to infrared frequencies means that it must be isolated from disruptive heat signals on Earth, and the telescope now rests at a gravitationally stable location beyond the moon's orbit — known as a Lagrange point — after being launched there from French Guiana atop an Ariane 5 rocket on Christmas Day 2021.
Since the telescope released its incredible first images on July 12, it's been flooding the web with photos of fascinating distant objects. The newly described record-breaking image was obtained during the Cosmic Evolution Early Release Science Survey — a deep- and wide-field sky survey conducted by the telescope. .—James Webb Space Telescope's 'jewel-filled' photo is stunning.
