There are two rival ideas to try and make sense of the Universe: dark matter or modified gravity. Can a new cosmic test settle the issue?
The newest find recovers the earliest merger in galactic history: just 2 billion years after the Big Bang. Here’s what we know today.
Short fiction is powerful because of its constraints. By compressing language and time, it achieves a singular intensity the novel cannot.
In an age of information overload, reliable sources are easy to access but often difficult to identify.
Recent evidence could indicate the Universe doesn't expand evenly. Does that change our expected fate: Big Rip, Big Crunch, or Heat Death?

Terence Tao breaks math down to six essential ideas: numbers, algebra, geometry, probability, analysis, and dynamics.
1859's Carrington event gave us a preview of how catastrophic the Sun could be for humanity. But it could get even worse than we imagined.

Science used to be broad because so few people could afford to do it. Now that more people can participate, the structures need to evolve too. Philosopher Alan Love explains.
We assume there's no preferred frame of reference in the Universe, and that light behaves the same in all directions. What if we're wrong?
The medicines already existed. The challenge was reaching people in time. Muso’s model of proactive community healthcare is showing what becomes possible when care moves closer to families.

Leadership isn't defined only by the biggest moments we face. It's shaped in the moments between them.
We've now found many "conjoined" objects in the asteroid and Kuiper belts, including the first contact trinary, Nysa. What does it all mean?
On Earth's surface, we accelerate at 1g: 9.8m/s². In orbit, the acceleration is only slightly less. So why, then, are astronauts weightless?
Newton thought that gravitation would happen instantly, propagating at infinite speeds. Einstein showed otherwise; gravity isn't instant.
