SATELLITES COULD MAKE FUTURE OF STARGAZING HAZY

Satellites could ruin astronomy for professional and amateur stargazers. OneWeb aims to launch 48,000 to create a global communications network. SpaceX wants to launch more than 41,000; Amazon wants 3,236; Facebook’s Athena is looking at 100,000. Studies show just 12,000 satellites would “seriously compromise” wide-field telescopes.
