New organic molecules discovered on Saturn’s moon Enceladus

Two years ago, the Cassini probe was sent plummeting into Saturn to its fiery demise – but researchers are still finding new discoveries in the data it sent back. Now, scientists from the Free University Berlin have reported findings from the CDA, the “Cosmic Dust Analyzer,” which was on board Cassini. This instrument was developed in Germany and was designed to study very small particles.

The CDA could detect particles with a velocity of 5 kilometers per second and a mass of only 1013 grams (a ten-millionth of a millionth of a gram, which corresponds to a size of two-thousands of a millimeter). In addition to the particle velocity and particle size (10 nanometers to 100 micrometers), it also determined the electrical charge of the particles and their basic composition.
