space...my other frontier

Q: What else would you have become if you could live long enough to have two full-blown careers?

A: I would have become an astronaut maybe even a cosmologist.  I am EXTREMELY fascinated by space.

Here is the latest view of Titan one of Jupiter’s many moons.  The moon we often fantasize about having life (although it is minus 290 degrees on the surface).

These three views of Titan from the Cassini spacecraft illustrate how different the same place can look in different wavelengths of light. Cassini's cameras have numerous filters that reveal features above and beneath the shroud of Titan's atmosphere.



The first image, a natural color composite, is a combination of images taken through three filters that are sensitive to red, green and violet light. It shows approximately what Titan would look like to the human eye: a hazy orange globe surrounded by a tenuous, bluish haze.

The second, monochrome view shows what Titan looks like at 938 nanometers, a near-infrared wavelength that allows Cassini to see through the hazy atmosphere and down to the surface.

The third view is a false-color composite.  Green represents areas where Cassini is able to see down to the surface. Red represents areas high in Titan's stratosphere where atmospheric methane is absorbing sunlight. Blue along the moon's outer edge represents visible violet wavelengths at which the upper atmosphere and detached hazes are better seen.

Just a few more pretty picture from the Hubble telescope of the Eagle nebula to decorate my journal...
