View Full Version : Ultraviolet Haze at Titan

2005-Nov-08, 05:15 PM
SUMMARY: Cassini snapped this picture of Titan on September 24, 2005, before its recent flyby. If you look carefully, you can see a thin haze hanging just above the surface of Titan's surface. This is part of Titan's atmosphere, visible at an altitude of 500 km (310 miles) above the surface of the moon. The particles in this part of the atmosphere are the exact size that scatters the ultraviolet light that reaches Cassini's cameras, which is why we can see it.

"snapped" (!)

To me that implies grabbing a photo with no thought, talent or skill.
How insulting.

Love your site but jeez (effin' writers!)

Interesting. Here is a better image of scattering (http://saturn.jpl.nasa.gov/multimedia/images/image-details.cfm?imageID=1512), IMO. There is a more stunning image of a purple halo around Titan, but I did not find it.

The article says the particles are comparable in diameter to the uv wavelength of 388nm. I would suspect the particles would be much smaller for Rayleigh scattering.
