Have you ever wondered why we always see the same side of the Moon? Although it may seem like the Moon doesn't rotate, it ...

A On some worlds, the sun never sets. Or rises. If a planet takes the same amount of time to spin once about its axis as it does to orbit once about its parent star, that star will appear to hang ...

In fact, this synchronous tidal locking process isn't unique to our Moon. Indeed, all the satellites in the table above—each planet's largest—are tidally locked to their host for the same ...

Tidal locking is bad news for life. If you're on a planet orbiting a red dwarf star, its light is so weak that you need to be smashed right up against that star to get in its habitable zone.

“The possibility of tidal locking is an old idea, but nobody had ever gone through it systematically,” said Barnes, who is affiliated with the UW-based Virtual Planetary Laboratory.

Methane Lakes: The surface features lakes, rivers and seas filled with liquid methane and ethane. The largest lake, Kraken ...

Therefore, they’re also likely to be tidally locked. Since humans may never be able to visit exoplanets in person, making sure computer models account for the effects of tidal locking is critical.
