Jupiter goes around its star in 180 days, which is a long time compared with most exoplanets we've discovered.

Although general relativity (GR) is an elegant theory of gravity, we don't often need to use it. For most gravitational ...

The solar system is a dynamic place, and objects located 180° from a planet don’t stay that far from the planet for long. The reason is the differences in their orbits. Orbits come in all shapes and ...

For most of human history, our view of “close to the Sun” was defined by the orbit of Mercury, with its 88-day orbit and barren, baking surface. But from the moment we started discovering exoplanets, ...

New measurements of radio galaxies reveal that the solar system is racing through the universe at over three times the speed predicted by standard cosmology. Using highly sensitive data from multiple ...

Imagine a world the size of Neptune, but instead of following the orderly path of its neighbors, it is racing headlong against the flow of its own solar system. In the case of the exoplanet TOI-1710 b ...

The orbits of a seven-planet system discovered in Kepler Space Telescope data has been sonified. Credit: Bishop’s University / Jason Rowe / NASA Ames Research Center GOP blocks Schumer's effort to ...

Hints of high-pressure chemistry within a rare meteorite suggest this fallen space rock comes from a planet gone wrong in the solar system’s early history NASA ordered its astronauts to take refuge ...

A Japanese spacecraft flew by an asteroid and snapped a picture. It turned out to be a “contact binary”: two space rocks that somehow fused together.

Between January and May of this year, the CRASH Clock dropped from 3.8 days down to just 2.5 days, bringing us closer to the ...
