The hits keep on coming with NASA ’S James Webb Space Telescope . According to the space agency, the JWST just found theever. The catchily-named JADES-GS-z14-0 galaxy is said to have formed just 290 million years after the big bang, but it features some unique properties that are at odds with that notion.
The galaxy is incredibly large, at 1,600 light years across. It’s also very bright and features an unusual amount of starlight, given how soon it formed after the big bang. This has led researchers Stefano Carniani and Kevin Hainline to ask “how can nature make such a bright, massive, and large galaxy in less than 300 million years?” In cosmic time, that’s barely a blip.
The wavelengths of light emitted from JADES-GS-z14-0, as spotted by the JWST’s MIRI , indicate the presence of strong ionized gas emissions, likely from an abundance of hydrogen and oxygen. This is also weird, as oxygen is not typically present early in the life of a galaxy. This suggests that “multiple generations of very massive stars had already lived their lives before we observed the galaxy.
“All of these observations, together, tell us that JADES-GS-z14-0 is not like the types of galaxies that have been predicted by theoretical models and computer simulations to exist in the very early universe,” the researchers told NASA. “It is likely that astronomers will find many such luminous galaxies, possibly at even earlier times, over the next decade with Webb.”, which was a first. All of this has been done in under two years of operation, so who knows what the future will bring.
