Astro2020
NASA astrophysics, which gave us Hubble, JWST, and so much more, faces its greatest budget cut in history. All future missions are at risk.
Diagram of the solar system with gravitational waves emanating from a distant bright source, and a triangular spacecraft array detecting the waves in space.
Just 10 years ago, humanity had never directly detected a single gravitational wave. We're closing in on 300 now, with so much more to come!
dark energy accelerated expansion
The fact that our Universe's expansion is accelerating implies that dark energy exists. But could it be even weirder than we've imagined?
symmetry
The laws of physics obey certain symmetries and defy others. It's theoretically tempting to add new ones, but reality doesn't agree.
Aerial view of winding rivers and wetlands showcases lush green vegetation and tan sediment-laden water converging with a larger body of water.
The award-winning nature writer, Robert Macfarlane, talks with Big Think about how to reacquaint ourselves with the rivers in our lives.
A healthcare worker wearing gloves administers an injection with a syringe into a person's upper arm, reminding us that when it comes to vaccines, do your own research and stay informed.
