‘Stars to completely disappear from night skies’

The News: “Scientists warn that, in 20 years time, humans may not be able to see a starry sky at night at all due to increasing light pollution. British astronomer Martin Rees, while talking with The Guardian, said that light pollution conditions have “rapidly worsened” over the past few years, quite significantly since 2016 when astronomers reported that the Milky Way was no longer visible to a third of humanity…”

  • See also ESO: “Starlink and other satellite operators have announced their plans to launch tens of thousands of satellites in addition to the couple of thousands of satellites already in orbit in 2019. This caused concern in the astronomical community (amateur and professional): will there be more satellites visible in the sky than stars? will astronomy still be possible? This page tries to give some answer, in a quantitative way, based on what is known about these satellites and what can be simulated. For more detailed information, including technical reports and publications, go to the Reports and Papers section.”
  • See also “The International Dark-Sky Association (IDA) is working to preserve the night sky for its cultural and scientific value and to do that it has worked with countries to create dark sky reserves around the world.  For an area to be certified as a Dark Sky Reserve it must meet the minimum criteria for sky quality and natural darkness and go through a rigorous application process with the IDA. You can learn more about their processes on the IDA’s official website…”
