Carnival Of The Space Geeks (Interstellar Travel Ain't Easy)

SpaceToys.com Authentic NASA Toys and Replicas
Last weeks Carnival of Space was hosted by Adam Crowl of Crowlspace (note: be sure to subscribe to his site feed as he has some great content over on his blog).

Many articles ranged from interstellar woes to Louis and Clark (note: it's space related) to even more silly arguments about the definition of a planet.

One article of interest that caught my eye was from Louise RioFrio (aka A Babe in the Universe) who posted an article about Enceladus.

(A Babe in the Universe) Back in December 007, the AGU meeting included a short talk by scientist Jennifer Meyer. The young woman asserted that Enceladus' 6 GW of heat can not be accounted for by tidal forces. The conventional estimate from tidal heating is only 0.12 GW. The old hypothesis or "radioactive decay" does not work for these icy moons. Why do so many worlds have hot spots on their poles?

On October 9 Cassini will make its closest flyby, passing only 25 km from Enceladus! Already the spacecraft has found tantalising data and spectacular photos. Little Enceladus could hold wonders not yet imagined. It could even hide a small Black Hole.
A black hole embedded within a tiny moon would probably spark more questions than answers, but it may also help explain why so much heat is pouring out from Enceladus.

Whether or not the source is discovered, Enceladus "warm nature" may prove to be ukseful towards future colonists in the form of geothermal energy.

Either way, be sure to read the rest of the articles, and for those of you seeking to inject your viewpoints regarding the cosmos, feel free to visit Universe Today for more details.

You can either visit the stars or watch them from afar.

But if you choose the former, you'll definitely get a better view.
