crow: Clouds on Mars, photographed by Mars Express, 4th October 2010.

36 to 43°S, 274 to 276°E on the highlands south of Solis Planum. The Coracis Fossae are somewhat visible at right running vertically down the image.

Coracis is derived from corax, the Latin name of the raven; thus the scientific name of the common or northern raven, Corvus corax.

Animation of 5 monochrome frames, colourized with a composite of 3 visible light images. The colour balance is not naturalistic, but probably close enough here.

Propylene on Titan

With a thick atmosphere, clouds, a rain cycle and giant lakes, Saturn’s large moon Titan is a surprisingly Earthlike place. But unlike on Earth, Titan’s surface is far too cold for liquid water - instead, Titan’s clouds, rain, and lakes consist of liquid hydrocarbons like methane and ethane (which exist as gases here on Earth). When these hydrocarbons evaporate and encounter ultraviolet radiation in Titan’s upper atmosphere, some of the molecules are broken apart and reassembled into longer hydrocarbons like ethylene and propane.

NASA’s Voyager 1 spacecraft first revealed the presence of several species of atmospheric hydrocarbons when it flew by Titan in 1980, but one molecule was curiously missing - propylene, the main ingredient in plastic number 5. Now, thanks to NASA’s Cassini spacecraft, scientists have detected propylene on Titan for the first time, solving a long-standing mystery about the solar system’s most Earthlike moon.

NASA PlanetaryScientist Conor Nixon explains his discovery of propylene on Titan, Saturn’s largest moon. Scientists have known about the presence of atmospheric hydrocarbons on Titan since Voyager 1 flew by in 1980, but one molecule, propylene, was curiously missing. Now, thanks to new data from NASA’s Cassini spacecraft, propylene has been detected for the first time on Titan.

Electric Fields Made Visible

Physics educator James Lincoln helps people understand the natural world. The gifs above are from a Youtube video he made on how to “see” an electric field, the region around a charged object where electric force is experienced. When the object is positively charged, electric field lines extend radially outward from the object. When the object is negatively charged, the lines extend radially inward.

Brinicles are super saline, super cooled water that sinks beneath the surface, freezing the water immediately around it. It continues sinking until it reaches the bottom, where it then starts to spread out covering the ocean floor with beautiful icicles.
