"When I was a child in the 1970s, seeing a satellite pass overhead in the night
sky was a rare event. Now it is commonplace: sit outside for a few minutes
after dark, and you can’t miss them.
Thousands of satellites have been launched into Earth orbit over the past
decade or so, with tens of thousands more planned in coming years. Many of
these will be in “mega-constellations” such as Starlink, which aim to cover the
entire globe.
These bright, shiny satellites are putting at risk our connection to the
cosmos, which has been important to humans for countless millennia and has
already been greatly diminished by the growth of cities and artificial
lighting. They are also posing a problem for astronomers – and hence for our
understanding of the universe.
In new research accepted for publication in
Astronomy and Astrophysics
Letters, we discovered Starlink satellites are also “leaking” radio signals
that interfere with radio astronomy. Even in a “radio quiet zone” in outback
Western Australia, we found the satellite emissions were far brighter than any
natural source in the sky."
