As usual, cross-posted from Tumbld Thoughts. This time, it's loosely-associated features on space science, space speculation, and science fiction. I, II, and III, respectively.
I. Space (Exploration) Simulation
Capture, stretch, and consume. The simulation discussed in this NY Times article  shows that the gas cloud G2  is about to collide with the massive black hole that forms the center of the Milky Way galaxy (Sagittarius A*).
II. Space (Futurism) Boosterism
Once the Singularity occurs (or perhaps slightly before), we will be able to terraform and colonize Mars. At least according to the optimists. See this Humanity+ article  by Nicole Willett from the Mars Society and this article in Current Biology  for more.
A day in the life of Darth Vader. From top: a morning stroll with the colleagues, pensively waiting in line at the local mall, and being put to sleep by Spock the home nurse after milk and cookies (not shown). And what roast of Darth Vader would be complete without a tip of the pen to Hanus  by the artist Jim Koch?
Yay, Hanus! That's all, Folks!
