Illustration for article titled When Enceladus And Tethys Align, Fantastic Pictures Happen

The Cassini spacecraft has snapped one brilliant picture: Saturn’s moons Enceladus and Tethys in alignment above their parent planet’s rings.

The picture was snapped on September 24th, as Enceladus drifted in front of Tethys.

At the time of the moon transit, Cassini was 1.3 million miles (2.1 million kilometers) from Enceladus and 1.6 million miles (2.6 million kilometers) from Tethys, meaning the 2 moons were only approximately 300,000 miles (500,000 kilometers) apart.

Really it should be “When Enceladus, Tethys, and Cassini Align” because geometrically speaking, two points are always in-line.
