JWST finds heavy elements in the universe’s first galaxies as NASA advances PRIMA far-infrared telescope

James Webb Space Telescope observations indicate that galaxies were producing and dispersing heavy elements just 500 million years after the Big Bang. Separately, NASA selected PRIMA, a far-infrared mission concept using spare Webb hardware, for further development toward a potential 2033 launch.

Briefing

What Hype is tracking

JWST’s findings challenge assumptions about the chemical purity of the early universe, showing that heavy-element production and dispersal began within 500 million years of the Big Bang.
NASA’s PRIMA selection establishes a new far-infrared mission class focused on the origins of planets and galaxies, with a potential 2033 launch.
Reusing spare Webb hardware could allow PRIMA to pursue major astrophysics objectives at lower cost and on a faster development timeline.
