NASAさんのインスタグラム写真 - (NASAInstagram)「NASA scientists have discovered a "weird" molecule in the atmosphere of one of Saturn's moons: Titan. 🙀 Many chemists have probably barely heard of it or know how to pronounce it: cyclopropenylidene, or C3H2. Scientists say that this simple carbon-based molecule may be a precursor to more complex compounds that could form or feed possible life on Titan. More info at the link in our bio! Image 1: The Cassini spacecraft captured this color portrait of Saturn and Titan only a few minutes before the haze-enshrouded moon slipped behind the planet's enormous bulk. The view looks toward the sunlit side of the rings from about 5 degrees below the ringplane (photojournal PIA09856, published March 12, 2008).

Titan has a dense atmosphere composed primarily of nitrogen with a few percent methane. The atmosphere can undergo photochemical processes to form hazes.

The view was created using years of data acquired by the Visual and Infrared Mapping Spectrometer instrument aboard NASA's Cassini spacecraft.
