Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas planets ...

On approach to Saturn, data obtained by the Cassini spacecraft are already posing a puzzling question: How long is the day on Saturn? On approach to Saturn, data obtained by the Cassini spacecraft are ...

NASA’s Cassini spacecraft executed a suicidal death plunge into Saturn’s atmosphere in 2017, but years’ worth of scientific data amassed by the spacecraft’s onboard instruments throughout its ...

Saturn's rings might have formed 100 million years ago when one of its icy moons was ripped apart by the planet's gravity. Though Cassini's findings were mostly welcomed, some planetary scientists ...

Saturn's rotation period has been a mystery. An estimate based on its meteorology comes with implications for our understanding of the planet's atmospheric jet streams and interior structure. You have ...

Using new data from NASA’s Cassini spacecraft, researchers believe they have solved a longstanding mystery of solar system science: the length of a day on Saturn. It’s 10 hours, 33 minutes and 38 ...
