Hubble telescope spots 'impossible' light from a galaxy that shouldn't have been visible - Live Science
Astronomers using the Hubble and James Webb space telescopes have detected ionizing ultraviolet light from an ancient galaxy, MXDFz4.4, that existed shortly after the Big Bang. This discovery challenges previous assumptions about the early universe's opacity and helps explain the Epoch of Reionization.
Why it matters
This finding provides critical data on how the early universe transitioned from a fog of neutral hydrogen to a transparent state, deepening our understanding of cosmic evolution.
Researchers say the surprising discovery of the faraway galaxy MXDFz4.4 could help explain how the cosmos went from opaque to transparent billions of years ago.
The report is purely scientific and relies on peer-reviewed findings without political or social framing.
