Newest Starlink satellites are leaking even more radiation than their predecessors — and could soon disrupt astronomy

By Harry Baker published

A new study reveals that Generation 2 Starlink satellites are leaking up to 30 times more radio waves than their predecessors. If SpaceX continues to deploy the newer versions as planned, we could reach an "inflection point" where astronomers can no longer properly study the cosmos, researchers warn.
