A recently resurfaced NASA image of Saturn’s moon Iapetus is stirring renewed interest across the internet, showing an ...

Here’s how it works. The light and dark faces of Saturn's moon Iapetus create a contrast that helped to hide the satellite for years, despite its distant orbit. The moon, which keeps the same ...

Iapetus, a moon of Saturn, has baffled astronomers since the early days of telescopic observation. It seemed to vanish and reappear without explanation, earning it a mythical status in early ...

The second Saturnian moon ever discovered -- Iapetus -- was immediately caught doing something no other moon had ever done: it was only visible for half of its orbit. The other 50% of the time ...

Two scientists propose an explanation for the bizarre ridge belting Saturn's moon Iapetus at the equator. At one time Iapetus itself may have had a satellite, created by a giant impact with ...

The origin of Iapetus's Janus faces is one of the longest standing mysteries in the solar system, one that has persisted since the moon's discovery by the astronomer Giovanni Cassini in 1671.

The first was obvious to Italian/French astronomer Giovanni Domenico Cassini soon after he discovered Iapetus in 1671, as it hovered on the right side of Saturn. After it slowly moved along its 79 ...

Saturn's moon Iapetus has many unique features that stand out even among the odd Solar System satellites. Its shape is very walnut-like: flattened at the poles, bulging strongly at the equator ...

The strangest feature on Iapetus is the equatorial ridge. What could possibly create a feature like this? To paraphrase the British geneticist J.B.S Haldane, "in my suspicion, the Universe is not ...

Saturn's ice moon Iapetus has more giant landslides than any solar system body other than Mars. Measurements of the avalanches suggest that some mechanism lowered their coefficients of friction so ...

One of the weirdest of the solar system’s moons is Iapetus. This is a medium-sized (1,471 km (914 miles) satellite of Saturn, orbiting about 3,561,300 km (2,213,000 miles) from the planet.

With data in from the Cassini probe's flyby of Saturn's Iapetus moon last month, scientists are now making progress in understanding the little satellite's unique features. The moon's division ...
