SpaceX’s plan to deliver widespread high-speed internet using satellites is upsetting stargazers everywhere. With 895 satellites already launched, and plans to launch another 12,000, the sky will be filled with mega-constellations of Starlink satellites whizzing through orbit.
Already, amateur and professional astronomers alike are upset by the satellites photobombing captured images and time-lapse photography of galaxies and constellations. But this is just the beginning.
Today in The Conversation Canada, Samantha Lawler from the University of Regina writes that soon, the sky could turn into a “mundane highway of moving lights, obscuring the stars,” ruining stargazing forever.
And that’s not even the half of it: SpaceX is also seeking permission to launch an additional 30,000, and other companies including Amazon are getting into the satellite game. And there’s the accompanying issue of space junk that needs to be addressed.

Resistant bacteria aren't the only risk posed by overprescribing antibiotics. A more immediate risk is side-effects and reactions, which a new review shows are surprisingly frequent and often severe.

The United States was built on the idea of public safety and well-being. Those values have been slowly eroded since the '80s. Can the U.S. find its way back to a more caring civil society?
