A new study examining some of Leonardo da Vinci's sketches in the Codex Arundel reveals the artist calculated the earth's gravitational constant at a 97% accuracy rate.

As we venture farther from Earth, we uncover powerful tools to fight disease, extend life and enhance human well-being. Central to these breakthroughs is the power of microgravity.

"Gravity is really tough, and that's what we feel when we get back," said astronaut Butch Wilmore, who will return to Earth with Sunita Williams, likely on March 19.

An artist's impression of Earth's gravity well. The idea that gravity is the result of the curvature of space-time is a core principle of Einstein's theory of general relativity.

Now, though, a new theory could finally give us the means to “see” gravity for the first time. The latest theory is based heavily on an old concept first explained by Albert Einstein back in 1905.

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as "fundamental" as gravity -- and could even give clues about possible life on other planets.
