Megaconstellations' Impact on Astronomy Raises Concerns.

Satellite megaconstellations, such as SpaceX's Starlink and Amazon's Project Kuiper, are causing concern for astronomers as they obstruct ground-based and space-based telescopes. While mitigation techniques have been developed to reduce the brightness of the satellites, they do little to lessen the impact on telescopes in low Earth orbit (LEO). Wide field-of-view telescopes, such as China's upcoming Xuntian telescope, will be more severely affected. As megaconstellations continue to grow, astronomers will need to adjust how they study the cosmos, potentially launching telescopes into higher orbits to limit the effects of satellite transits.
