Over the decades, astronomers have faced the increasingly tough problem of satellites appearing in their view of the universe. The rapid growth of Starlink, SpaceX's web-from-space system, isn't just impacting countless pictures using visible light but also those in other parts of the spectrum. A recent study of 76 million images shows that the satellites are affecting the work of radio astronomers, even at frequencies that the satellites don't transmit at.
Take a photograph of the night sky, far away from any urban lights, and you stand a good chance of capturing the telltale streak of a satellite passing overhead. For any ground-based telescope capturing the faint photons of visible light from distant stars, it's an unavoidable problem because the satellites will always reflect the Sun's light.
