Enceladus Curtains: Comparing Data and Simulation

Phantom jets in simulated images produced by the scientists line up nicely with some of the features in real images from NASA Cassini spacecraft that appear to be discrete columns of spray.

☄️ And again the clouds cleared at dusk.

The tail shows some nice detail. The curved shapes happen because the comet rotates on an axis as it outgasses and ejects dust from its surface.

At the moment that dust is is picked up by the solar wind and pushed out away from the Sun. The comet itself is also on its way back to the outer reaches of the solar system, never to be seen again.
