Scientists have detected a faraway galaxy leaking ionizing radiation, offering clues about how the early universe transformed during reionization. This discovery could reshape our understanding of cosmic evolution.

KEY TAKEAWAY The galaxy, named JD1, is 13 billion light-years away and leaks Lyman continuum photons.

KEY TAKEAWAY Its radiation may have helped ionize neutral hydrogen during reionization.

KEY TAKEAWAY The team used the James Webb Space Telescope (JWST) to confirm the leak.

KEY TAKEAWAY Understanding these galaxies could explain how the universe became transparent.

KEY FACT JD1’s light has traveled 13 billion years, meaning we see it as it was just 700 million years after the Big Bang.
