Shedding light on the gravity of the situation. Most people do not realize that many of the stars and heavenly bodies they see in the sky no longer exist. In fact, many have ceased to exist for ...

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. A team of NASA ...

Astronomers observe for the first time the actual motion of spirals in a protoplanetary disk, revealing gravitational ...

European scientists are turning an aircraft into a laboratory that simulates lunar gravity to prepare astronauts and ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for ...

Warm Jupiters are rewriting the rules of planet formation - showing eccentric orbits that stay strangely aligned with their ...

Evidence pointing toward the existence of an undiscovered ninth planet in the solar system may actually indicate our ideas of gravity are incorrect. Such is the conclusion of two scientists who ...

Our solar system officially houses eight planets, but some scientists say there could be a ninth. And that’s not just Pluto aficionados – evidence suggests a huge undiscovered world lurks on the dark ...

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it — very, very carefully. This is ...

More than a 150 years ago, before Neptune was ever sighted in the night sky, French mathematician Urbain Le Verrier predicted the planet’s existence based on small deviations in the motion of Uranus.

A pair of theoretical physicists are reporting that the same observations inspiring the hunt for a ninth planet might instead be evidence within the solar system of a modified law of gravity ...
