Named for its discoverer's nine-year-old daughter, this galaxy is one of the oldest realms to be witnessed by humanity.
. Eventually, that light can even tread into infrared waters. Infrared light is basically invisible to human eyes.
"We really could not see it before the JWST," he explained."The Hubble Space Telescope was neither big enough nor, most importantly, did it cover 'red enough' wavelengths to see such a distant, highly redshifted galaxy." This means Maisie's galaxy is technically seen more recently in the universe than initially estimated, by a factor of tens of millions of years. Nonetheless, it is still considered immensely old. The JWST captured the galaxy as it was just 390 million years after the Big Bang.Finkelstein explained that Maisie's galaxy would be distinguishable from galaxies in the universe today, including the Milky Way, as it is much smaller.
