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.

The latest generation of SpaceX's Starlink satellites are leaking even more potentially disruptive radiation into low-Earth orbit than their predecessors, a new study shows. Researchers warn that the continuing unchecked deployment of the spacecraft could lead to an irreversible "inflection point," beyond which we can no longer properly study the universe's most exciting objects.

In July 2023, researchers discovered that SpaceX's Generation 1 Starlink satellites, first launched in 2019, are leaking unintended electromagnetic radiation (UEMR) into space. This radiation, which mainly consists of radio waves, is inadvertently given off by the satellites in multiple directions as they transmit radio signals to Earth. Unfortunately, these radio wave frequencies are very similar to those emitted by distant objects from across the cosmos, such as stars, exoplanets, black holes and pulsars, meaning that leakage from the satellites can obscure radio astronomers' readings.

Over the last year and a half, SpaceX has been phasing out these satellites in favor of newer Generation 2 models , which were first launched in February 2023. These spacecraft are smaller,more powerful, maneuverable and robust than their predecessors, according to Live Science's sister site Space.com. However, until now, it was unclear if they also leaked UEMR.
