Starlink checks present the best way to save radio astronomy from satellites

Radio telescopes observing the cosmos face rising challenges due to electromagnetic interference from 1000’s of satellites in low Earth orbit. Now, experiments involving SpaceX’s Starlink satellites have proven the best way to nearly eradicate one type of this drawback.

As these form of satellites hurtle across the planet, they ship so-called downlink alerts to Earth to supply web and communication companies. After they go by means of areas of the sky the place radio telescopes are observing, the momentary blips from these sturdy alerts can probably influence hours of…
