An international team of scientists has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields. Known as the ambipolar electric ...

The Moon’s atmosphere contains about one million billion (10 15) times fewer molecules per cubic centimeter than Earth’s does. This is primarily because Earth is more massive (so it has a stronger ...

Telescopes located in Hawaii and elsewhere continuously scan the sky in search of near-Earth asteroids – small, irregular, rocky objects left over from the formation of our solar system. The ...

Groundbreaking “camera-on-a-chip” technology that was originally developed at NASA’s Jet Propulsion Laboratory (JPL) for use in space missions is currently employed in billions of devices like cell ...

What causes a solar storm? The Sun creates a tangled mess of magnetic fields — kind of like a disheveled head of hair after a fitful night of sleep. These magnetic fields get twisted up as the Sun ...

Fires in Quebec have delivered one of the most intense outbreaks of smoke seen in the eastern U.S. in decades.
