Hubble Finds a Stunning Twist in How the Universe Emerged From Darkness

Hubble reveals a stunning twist in how the universe emerged from darkness

A surprising discovery by astronomers using the Hubble Space Telescope is challenging a leading explanation for how the early universe emerged from a dense fog of hydrogen roughly 13 billion years ago. Scientists once believed powerful winds from exploding stars helped radiation escape galaxies and clear that cosmic fog, but new observations reveal that these winds actually block radiation instead.

Hubble Finds a Stunning Twist in How the Universe Emerged From Darkness

Hubble observations of nearby starburst galaxies challenge the idea that supernova winds helped reionize the early universe, suggesting young stars may have enabled radiation to escape before those winds formed. Powerful winds from exploding stars were thought to clear paths for ultraviolet radiation to escape early galaxies. A new study of nearby galaxies suggests those [...]

Hubble Reveals a Surprising Discovery About How the Universe Emerged from Darkness

Astronomers using NASA’s Hubble Space Telescope have found that powerful winds from exploding stars may make it harder—not easier—for ultraviolet radiation to escape early galaxies. The result challenges a widely accepted explanation for how the early universe became transparent during reionization, suggesting that ionizing photons may have escaped before the first supernovae reshaped their surroundings.

Hubble Study and Supernova Winds in Hubble reionization study

A study of six nearby galaxies suggests young stars may help ultraviolet light escape, vital to the Hubble reionization study.
