This equates to a galaxy seen just 330 million years after the big bang, a small fraction of the universe\u2019s present age of 13.8 billion years old. But an unexpected feature stood out as well: one specific, distinctly bright wavelength of light, known as Lyman-alpha emission, radiated by hydrogen atoms. This emission was far stronger than astronomers thought possible at this early stage in the universe\u2019s development.<\/p>\n<p>\u201cThe early universe was bathed in a thick fog of neutral hydrogen,\u201d explained Roberto Maiolino, a team member from the University of Cambridge and University College London. \u201cMost of this haze was lifted in a process called reionization, which was completed about one billion years after the big bang. GS-z13-1 is seen when the universe was only 330 million years old, yet it shows a surprisingly clear, telltale signature of Lyman-alpha emission that can only be seen once the surrounding fog has fully lifted.

The galaxy JADES-GS-z13-1, observed just 330 million years after the big bang (corresponding to a redshift of z=13.05), shows bright emission from hydrogen known as Lyman-alpha emission. This is surprising because that emission should have been absorbed by a dense fog of neutral hydrogen that suffused the early universe.<\/div>\n<div class=\"hds-credits\">NASA, ESA, CSA, J. Witstok (University of Cambridge, University of Copenhagen), J. Olmsted (STScI)<\/div>\n<\/figcaption><\/div>\n<\/div>\n<\/div>\n<p>Before and during the <a href=\"https:\/\/webbtelescope.org\/contents\/media\/images\/2020\/37\/4697-Image\"  rel=\"noreferrer noopener\">era of reionization<\/a>, the immense amounts of neutral hydrogen fog surrounding galaxies blocked any energetic ultraviolet light they emitted, much like the filtering effect of colored glass. Until enough stars had formed and were able to ionize the hydrogen gas, no such light \u2014 including Lyman-alpha emission \u2014 could escape from these fledgling galaxies to reach Earth. The confirmation of Lyman-alpha radiation from this galaxy, therefore, has great implications for our understanding of the early universe.<\/p>\n<p>\u201cWe really shouldn\u2019t have found a galaxy like this, given our understanding of the way the universe has evolved,\u201d said Kevin Hainline, a team member from the University of Arizona. \u201cWe could think of the early universe as shrouded with a thick fog that would make it exceedingly difficult to find even powerful lighthouses peeking through, yet here we see the beam of light from this galaxy piercing the veil. This fascinating emission line has huge ramifications for how and when the universe reionized.\u201d<\/p>\n<p>The source of the Lyman-alpha radiation from this galaxy is not yet known, but it may include the first light from the earliest generation of stars to form in the universe.<\/p>\n<p>\u201cThe large bubble of ionized hydrogen surrounding this galaxy might have been created by a peculiar population of stars \u2014 much more massive, hotter, and more luminous than stars formed at later epochs, and possibly representative of the first generation of stars,\u201d said Witstok.
