A giant planet in the HR 8799 system orbits six times faster than its neighbor, reigniting the mystery surrounding its origin ...

The largest survey of exoplanets using an observatory atop Maunakea on the Big Island confirms a long-predicted relationship between planetary mass and rotation — putting a new spin on planet ...

For some time, astronomers have theorized that there is a connection between planetary mass and rotation. In the solar system ...

NASA’s James Webb Space Telescope and Hubble Space Telescope have produced a detailed paired view of Saturn, and the images ...

Scientists announced Monday that Earth is rotating slightly faster than normal, resulting in what is expected to become the second-shortest day ever recorded since precise atomic timekeeping began.

The internal, infernal machinations of our planet may be way more complex than we suspected. A new, detailed probe of Earth's heart reveals that the rotating inner core doesn't just change in rotation ...

Saturn’s northern lights heat one side of the planet’s upper atmosphere and drive winds that mimic changes in its spin.

For nearly a billion years, Earth’s rotation stopped slowing down. Locked in a rare cosmic balance, the planet’s day remained fixed at 19 hours, stalling the normal progression toward longer days.

This could help explain a lot. The post Scientists Intrigued by “Negative Mass Anomaly” Under Surface of Mars appeared first on Futurism.

Thanks to NASA's Cassini spacecraft which has been orbiting Saturn since 2004, scientists have been able to observe for the first time ever the seasonal atmospheric circulation direction change on ...
