Faint signatures detected by the Canada France Hawaii Telescope have revealed 128 new moons around Saturn, making it the ...

The study suggests changes are occurring deep within our planet, which could have implications ... and in the opposite direction relative to the rotation of the Earth's surface.

The gas giant WASP-121b, also known as Tylos, has an atmospheric structure unlike any we have ever seen, and the fastest ...

Each planet has a different timeframe for complete rotation around the sun so all of them coming into alignment to be visible from Earth is a rare sight. The next alignment of five planets or more ...

The planet WASP-121b is extreme. It's a gas giant almost twice as big as Jupiter orbiting extremely close to its star–50 ...

By the laws of physics, the slowest the Earth could slow its spin would be 1 rotation every 365 days. That situation is called "sun-synchronous" and would force one side of our planet to always ...

“These moons are a few kilometers in size and are likely all fragments of a smaller number of originally captured moons that were broken apart by violent collisions, either with other Saturnian moons ...

Mars' atmosphere moves differently from Earth's due to gravity waves. These waves affect air circulation at high altitudes.

while Kepler-62's exoplanet has a 155-day rotation period. While both planets would likely be locked into a synchronous orbit—with a permanent dayside and a perpetual nightside—the ultrafast ...
