Carnival of Space week 47 is up at Martian Chronicles.
I had contributed my article on fermi paradox related science and a pictorial review of oceans in our solar system.
Centauri Dreams also talked about the possible ocean on Titan and the habitable zone of solar systems.
Colony Worlds talks about the Bigelow inflatable space stations and spinning them for simulated gravity.
Hobbyspace has a lot of coverage of the XCOR Lynx rocket plane.
Bad Astronomy's Phil Phait had an asteroid named after him.
Astroengine talks about building a laser with a black hole.
