"James Webb Telescope Captures Stunning New Details of the Universe"

NASA's James Webb Space Telescope has captured a stunning image of the Hubble Ultra Deep Field, a faraway region in the southern constellation Fornax containing at least 10,000 galaxies dating back to just 800 million years after the Big Bang. The image, taken in infrared wavelengths, is helping astronomers piece together the universe's history in the first billion years after the Big Bang, known as the reionization era. Webb observed the same region at similar depths that Hubble did, but in just one-tenth as much observing time, and is unveiling young galaxies that were not seen previously.

"Webb Telescope Reveals Stunning New Views of the Universe"

NASA's James Webb Space Telescope has captured a stunning image of the Hubble Ultra Deep Field, a faraway region in the southern constellation Fornax containing at least 10,000 galaxies dating back to just 800 million years after the Big Bang. The image, snapped in infrared wavelengths by JWST's Near-Infrared Camera, is helping astronomers piece together the universe's history in the first billion years after the Big Bang. The reionization era is when the first cohort of stars were born, and galaxies this early on were not as well defined as the ones we see closer to our Milky Way.
