Das James-Webb-Weltraumteleskop entdeckt drei der frühesten Galaxien unseres Universums

„About 400,000 years after the Big Bang, our universe was ushered into darkness. This occurred after space had cooled down enough from its formerly chaotic and scorching self to allow neutral hydrogen atoms to form, which blanketed the cosmos in an opaque primordial fog. That fog lifted about 1 billion years after the Big Bang, when light from the first generation of stars flooded the universe. Recent research has shown dwarf galaxies that formed during the first few hundred million years of the universe packed a surprisingly abundant punch to drive this fog-relieving process.“
