Grandiose Canyons on a Saturn Moon, Filled With Liquid Methane

Deep, narrow canyons on Titan, Saturn’s largest moon, are flooded with liquid methane and other hydrocarbons, radar data from NASA’s Cassini spacecraft has found.

Titan, the Saturn moon with a diameter one and a half times that of Earth’s moon, is a surprisingly complex world. It has three large seas, a thick covering of haze and clouds, and surface contours carved by erosion — despite temperatures of about minus 300 degrees Fahrenheit (minus 184 Celsius).

“For many things, it is similar to our planet,” said Valerio Poggiali of the University of Rome, and a member of the Cassini spacecraft mission’s radar team. “That is why we consider Titan really a laboratory for a deeper understanding of our home planet.”

Yea me too. Nothing like a picture of the known universe to make us feel tiny.

We're rather puny, huh! I like this graph.

I have several wallpapers of space.

ESA and NASA’s Solar and Heliospheric Observatory, or SOHO, saw a bright comet plunge toward the sun on Aug. 3-4, 2016, at nearly 1.3 million miles per hour. Comets are chunks of ice and dust that orbit the sun, usually on highly elliptical orbits that carry them far beyond the orbit of Pluto at their farthest points. This comet, first spotted by SOHO on Aug. 1, is part of the Kreutz family of comets, a group of comets with related orbits that broke off of a huge comet several centuries ago.

This comet didn’t fall into the sun, but rather whipped around it – or at least, it would have if it had survived its journey. Like most sungrazing comets, this comet was torn apart and vaporized by the intense forces near the sun.

The disk of the sun is represented by the white circle in this image.

Mind boggling!
