The Cassini Orbiter is about 5,000 pounds (minus its fuel, which is all gone, and the Huygens probe it dropped off on Titan in 2004) of science that’s been orbiting Saturn for nearly 13 years. It is, by any objective take, a vanishingly small speck in the vastness of space, and one of the subtle feats of its 12 sensors—including an ultraviolet imaging spectrograph, plasma spectrometer, and cosmic dust analyzer—is reminding…

Bubbles may put mysterious fizz in Titan’s polar sea

Titan magic island
SHAPESHIFTER Nitrogen bubbles may be the source of an on-again, off-again bright spot, or “magic island,” on Saturn’s moon Titan. Cassini spacecraft images of the island, which sits in a hydrocarbon sea called Ligeia Mare, revealed the feature’s fickle nature.

Saturn’s main moon, Titan, has a “magic island,” which might be made of streams of nitrogen bubbles, scientists report April 18 in Nature Astronomy.

Images from NASA’s Cassini spacecraft show that the island, which appears as a bright spot,…
