More satellites than ever are being launched globally — but their reflections threaten to stop us from seeing many of our stars at night. 

University of Southern Queensland PhD student Jessica Heim was part of a team that studied the issue and compiled new evidence that quantifies the extent of the problem.

In this episode, she tells host Adam Thorn what can be done to solve the problem and its threat to science and culture.

The pair also discuss the importance of safeguarding the night sky to inspire the next generation into the industry.
