NewsSpaceJWST spots the earliest sign yet of a distant galaxy reshaping its cosmic environsThe marker is an unexpected bubble that could signal cosmic reionization earlier than thought The extremely distant galaxy JADES-GS-z13-1 is the small red dot in the center of this image from the James Webb Space Telescope. New observations show the galaxy is emitting a surprising amount of ultraviolet light, indicating it is radically reshaping the cosmic landscape around it.JWST/ESA, NASA, STScI, CSA, JADES Collaboration, Brant Robertson/UC Santa Cruz, Ben Johnson/CfA, Sandro Tacchella/U. of Cambridge, Phill Cargile/CfA, J.

Zamani/JWST/ESA)By Lisa Grossman19 seconds agoThe James Webb Space Telescope has caught a distant galaxy blowing an unexpected bubble in the gas around it, just 330 million years after the Big Bang.The galaxy, dubbed JADES-GS-z13-1, marks the earliest sign yet spotted of the era of cosmic reionization, a transformative period in the universes history when the first stars and galaxies began to reshape their environment, astronomers report in the March 27 Nature.It definitely puts a pin in the map of the first point where [reionization] very likely has already started, says astrophysicist Joris Witstok at the University of Copenhagen. No one had predicted that it would be this early in the universes history.
