Story summary

Astronomers identified a hidden population of quasars using Japan’s Subaru Telescope and NASA’s James Webb Space Telescope (JWST).
They confirmed seven quasars from less than a billion years after the Big Bang, doubling the known count from that period.
Quasars influence star formation by emitting radiation that impacts surrounding gas.
The research seeks to understand the rapid growth of supermassive black holes during the Cosmic Dawn.
Future studies will compare these dust-obscured quasars with their dust-free counterparts.
