It’s both massive and extremely diffuse.

The “oddball” satellite has astronomers wondering what else they’re missing.

50 years of discovery — and he’s not done yet.

Once again, the decades-old theory of gravity has survived a modern scientific onslaught. Einstein wins again.

The first big international effort to combat mercury pollution is zeroing in on small gold mines, which account for almost half of annual emissions.

Physicists have created atomic clocks so precise that they can measure deformations in spacetime itself, according to new research.

We don’t all experience time passing equally—time passes more slowly closer to something massive’s gravitational pull, as famously theorized by Albert Einstein. And since gravity is typically interpreted as the way mass warps space itself, that means a precise-enough atomic clock could serve as a scientific tool for measuring how objects change the shape of their surrounding space.

A new Mars rover will look for life—but there’s a fight over where it should search.

Moon again?

Mars just received its newest robotic resident. Our NASA InSight lander successfully touched down on the surface of the Red Planet yesterday after its 300-million-mile journey from Earth. Learn what insights we hope to gain from it and get your Mars on: https://go.nasa.gov/2FJEygW
