Saturn's Day Could Be Shorter Than Previously Thought

We certainly know how long our own day is, and Mars is not much longer (24 hours and 40 min). The closest planet to the Sun, Mercury's own incredibly long day lasts more than 1,407 hours. What's interesting, however, is that astronomers know all this with near certainty. That's not the case for Saturn, on the other hand, whose day length has remained something of an enigma.
