Saturn’s Rings

  Cassini captured this image of the Saturn rings and the little moon Prometheus. I got to thinking about the early drawings, in particular the famous 1666 drawing by Robert Hooke showing the shadows from the planet and rings. As an aside, Robert Hooke is probably one of the most famous scientists¬many¬school kids have never […]

Cassini finds evidence for hydrothermal activity on Saturn's moon Enceladus

The deep oceans on Earth are teeming with life, despite the cold and darkness, thanks to hydrothermal vents which provide needed heat and nutrients in an otherwise rather uncomfortable environment. Now, the first evidence has been found for current hydrothermal activity elsewhere in the Solar System: on the ocean bottom of Saturn's moon Enceladus. These […]The post Cassini finds evidence for hydrothermal activity on Saturn's moon Enceladus appeared first on .

Iapetus

Here's an image of the Saturn moon Iapetus from the Cassini spacecraft. It is the third largest moon of Saturn with a diameter of 1,417 km / 914 miles or about 40 percent of our moon . Iapetus has density … Continue reading →

Life not as we know it': new research shows how exotic biology may be possible on Titan

The search for life elsewhere has long focused on what we are most familiar with on Earth – in other words, life as we know it, or organisms which are carbon-based and require water to survive. However, a growing number of scientists are now thinking that alternative forms of life are possible, ones which have […]The post ‘Life not as we know it': new research shows how exotic biology may be possible on Titan appeared first on .

Cubist Saturn

Cubism is an artistic movement that featured surfaces of geometrical planes in France beginning in the early 1900's. Cassini got into the act back in December 2014 with this image. Usually I find cubist art pretty straightforward, ¬this one is¬a … Continue reading →

Exploring an alien sea: NASA designs submarine to send to Titan

Who wouldn't want to go explore an alien sea? It seems that NASA would certainly like to, and the agency has unveiled a new submarine design to hopefully do just that one day. The submarine would be sent to Saturn's largest moon, Titan, to dive into one of the large liquid methane seas on the […]The post Exploring an alien sea: NASA designs submarine to send to Titan appeared first on .

New technique provides better, clearer radar images of Titan's amazing surface

Saturn's largest moon Titan is a fascinating world, uniquely alien yet eerily Earth-like in many ways, with its rain, rivers, lakes, seas, and massive sand dunes. But in this extremely cold environment, it is liquid methane and ethane which act as water, mimicking the hydrological cycle on Earth. Also, due to the perpetual and global […]The post New technique provides better, clearer radar images of Titan's amazing surface appeared first on .

Cassini data indicates Enceladus' ocean similar to soda lakes on Earth

Along with Jupiter's infamous moon Europa, Saturn's moon Enceladus is one of the most fascinating places in the Solar System, with its huge geysers of water vapour erupting from cracks in the surface at the south pole. The massive plumes are now thought to originate in a subsurface ocean or sea of salty liquid water, […]The post Cassini data indicates Enceladus' ocean similar to soda lakes on Earth appeared first on .
