James Webb Space Telescope tracks a galaxy’s history back to just after the Big Bang

“A long time ago, in a galaxy not so far away…”

Astronomers have used the James Webb Space Telescope (JWST) to map out the history of stars in a low-mass dwarf galaxy that resembles galaxies that filled the early universe. The research could help better understand how star formation rates have changed over the last 13 billion or so years since time began.
