We finally know what brought light to the dark and formless void of the early Universe.
According to data from the Hubble and James Webb Space Telescopes, the origins of the free-flying photons in the early cosmic dawn were small dwarf galaxies that flared to life, clearing the fog of murky hydrogen that filled intergalactic space.
"This discovery unveils the crucial role played by ultra-faint galaxies in the early Universe's evolution," says astrophysicist Iryna Chemerynska of the Institut d'Astrophysique de Paris.
"They produce ionizing photons that transform neutral hydrogen into ionized plasma during cosmic reionization. It highlights the importance of understanding low-mass galaxies in shaping the Universe's history." READ MORE...
