Carnival of Space #136 @ Simostronomy

The 136th edition of the Carnival of Space, a weekly series highlighting the best in the astronomy and space blogosphere, is now online at Simostronomy.  You know the drill.  Some great posts on the 6th anniversary of the Mars rover Spirit's landing, the refined age of the solar system, and faint galaxies on the edge of the visible universe, brought to us by Hubble, upgraded last year.
