Starlink satellite emissions interfere with #radio #astronomy.

The largest-ever survey of low-frequency radio emissions from satellites has detected emissions from the #Starlink satellite “mega-constellation” across scientifically important low-frequency bands, including some that are protected for radio astronomy by international regulations.

These emissions, which come from onboard electronics and are not intentional transmissions, could mask the weak radio-wave signals that astronomers seek to detect.

As well as being damaging for radio astronomy, the researchers who conducted the survey say their findings highlight the need for new regulations that cover unintended transmissions, not just deliberate ones.
