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

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 ...

The Indian Ocean Geoid Low ranks as the largest negative "gravity hole" anomaly on Earth, which is why the “thumbprint” jumps ...

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

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 ...

Satellites detected a strange gravity signal off the coast of Africa nearly 20 years ago, suggesting something unusual had ...

The GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex ...

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

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 ...

Every planet in our solar system is essentially round. But out in the universe, are there any planets that aren't spherical? Technically, planets are round, by definition; they need to have enough ...
