From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

It's the reliable celestial companion that's stuck around for 4.5 billion years. But the moon is slowly drifting away from ...

Long ago, the Moon was much nearer Earth. Scientists believe a protoplanet collision created the Moon 4.5 billion years ago.

It may shock you, but on an industrial scale, electricity is rarely generated in reserve. If fuel or water power is used to generate energy, then the process can be regulated and not generate excess ...

Early scientific theories—such as those explaining basic phenomena like gravity, burning, and the movement of molecules in ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases ...

So the bottom line is that the gravity of the closer tidal bulge on the Earth is pulling the Moon forward, which increases the size of the Moon’s orbit. This means that the Moon gets slightly farther ...

The Museum of Illusions isn’t just another stop on the tourist trail—it’s a mind-altering journey that has Ohioans hitting the road from Cincinnati to Toledo just to experience it. Your brain is about ...

A swarm of galaxies called the Bullet Cluster is the biggest, best natural laboratory for studying dark matter that ...

Astronomers detected in unprecedented detail a collision between two black holes. Their observations confirm predictions made by Albert Einstein and Stephen Hawking.

Ten years ago, scientists heard the universe rumble for the first time. That first discovery of gravitational waves proved a ...

A decade after the first discovery, scientists have used these waves to find a unique merger, a massive binary system and a ...
