During his Administration, Hurricane Maria knocked out power to 1.5 million people in Puerto Rico and it didn’t get restored for ABOUT A YEAR! It was the largest blackout in U.S. history. This should be line one of any hurricane recovery political coverage. www.vox.com/identities/2...

How and when did astronomers begin to understand access to the #night sky as a human right? And what are the implications of doing so? 🌌

I’ve noticed the uptick in satellite pollution since Starkink launched and it really ruins the beauty of the night sky— more than that— it negatively impacts astronomical observations and impedes discoveries. Stargazing and wonder is a human right

The FCC just opened public comments on SpaceX's plan to launch a million satellites to do AI compute in space. Under the current proposal, an environmental review won't be required. Please consider submitting a public comment to oppose this damaging plan.
