The planet Neptune was discovered in 1846 following laborious calculations by Englishman John Couch Adams (1819-1892) and Frenchman Urbain Leverrier (1811-1877). These astronomers, attempting to explain deviations noted in the orbit of Uranus,...

Neptune is the most distant giant planet, circling the Sun at an average distance of almost 6 billion kilometers (3.7 billion miles; thirty-nine times the distance from Earth to the Sun). Neptune is a near twin to Uranus in size (with a radius of...

In 1781 Sir William Herschel discovered the planet Uranus, an event that doubled the size of the solar system. After extensive observation, astronomers soon realized that its orbit was inconsistent and, moreover, was being disturbed by the...

Neptune is the eighth planet in the solar system with respect to its average distance from the Sun. It is the outermost of the giant gas planets (along with Jupiter, Saturn, and Uranus). The discovery of Neptune was one of the triumphs of mathematical...

Neptune (pronounced /ˈnɛptjuːn/) is the eighth and furthest planet from the Sun in the Solar System. It is the fourth largest planet by diameter, and the third largest by mass. Neptune is 17 times the mass of Earth and is slightly more massive than...

For centuries, Neptune, the eighth planet from the sun, has been viewed--when visible at all--as the drab stepsister to other planets in our solar system. Then in 1989, NASA's Voyager 2 flew by the fuzzy nobody and sent snapshots to Earth. Those startling...

Astronomers look for rules. They seek theories and develop models that tidily explain how planets form, how moons move, and how the universe came to look the way it does. But these scientists also keep finding exceptions to their rules. In our...

Scientists say that Neptune, one of the coldest planets in the solar system, has a surprising warm spot _ relatively speaking. An international team of astronomers has found that Neptune's south pole is warmer than other parts of the planet.Temperatures at its south pole are...

Once most people get a taste for the champagne lifestyle, they’re terrified to go back to Bud. That’s why this compilation is so fascinating: Chad Hugo and Pharrell Williams remain defiantly oddball, despite their immense commercial success. This will come as no surprise to fans...
