    As megaconstellations grow, scientists become concerned with their impacts on astronomy

    by Ian Atkinson April 23, 2023
    written by Ian Atkinson

    Since their initial launch in 2019, SpaceX’s Starlink internet satellites have become infamous for photobombing observations from ground-based telescopes. While Starlink — along with other satellite “megaconstellations” — has been a primary concern for ground-based telescope observations, a new issue has begun to pop up; the satellites are now occasionally obstructing images from one of NASA’s flagship space telescopes, the Hubble Space Telescope. These “photobombings” point to a concerning future for astronomy in low Earth orbit (LEO), as telescopes in LEO may begin to face the same problems ground-based telescopes face today — especially as these satellite megaconstellations grow.

    To learn more about this growing issue, NSF sat down with astrophysicist Dr. Jonathan McDowell from the Harvard-Smithsonian Center for Astrophysics to discuss the topic.
