The Horsehead Nebula

Horsehead Nebula (Horsehead Nebula) or Barnard 33 (B33) is a cold, dark cloud of gas, located about 1,500 light years from Earth, south of the left end of the belt of Orion. Complex is part of the Orion Molecular Cloud, and is approximately 3.5 light-years across. This dark nebula is visible by contrast, since it appears in front of the emission nebula IC 434. Its shape is the most familiar of absorption nebulae.

The reddish emission nebula is caused by the recombination of electrons and protons from hydrogen atoms. The brightest star to the left of the nebula is the popular Alnitak (ζ Orionis) of Orion's Belt. The unusual shape of Horsehead was first discovered on a photographic plate in the late nineteenth century by Williamina Fleming, in the Harvard College Observatory. The first to include a catalog of the Horsehead Nebula was Edward Emerson Barnard of Barnard Family in 1919

2 percent of the results are in and it looks like Pluto has active geology.

The heart is made of carbon monoxide ice. The atmosphere extends farther than expected. There also appears to be either wind or geysers affecting the surface.

I would theorize Pluto's internal structure is analogous to Titan with an outer atmosphere of gaseous methane, a surface of various methane and nitrogen ices (no liquids in this case), and a layer of salty water ice in place of a mantle. The core is probably iron or nickel and may be active in my opinion.

Like Titan, Pluto probably experiences Cryovolcanism in which cold water ice (much warmer than the surface ices) burns through and creates "ice lava" across the surface.

Unlike Titan, Pluto experiences no tidal flexing from gravitational proximity to Saturn for creating internal heat. I believe the eliptical orbit of the planet explains this as going closer and farther from the sun heats and freezes the core. In this sense Pluto's geology may be seasonal, with eruptions in the Plutonian Summer (when farthest from the Sun) and inactivity and ice resurfacing in winter.

The atmosphere may also freeze through this process.

What can you see with a telescope?  You can observe or photograph the heavens on a casual or serious basis, undertake scientific study or marvel at the wonderment of our existence...  http://goo.gl/wPpO7M

Look outside with a small telescope tonight and you might see Venus and Jupiter less than a degree apart.
