If you know about 'Carnival of Space' you can stop reading now and just go here to read it this week.
'Carnival' is a weekly collection of samples from space, science and astronomy blogs all brought together under one roof on one host site each week. This week's collection is really quite good. There are deep, serious scientific discussions, some very good humor and even a bit of philosophical musing.
The rest you can find out for yourself by visiting Mang's Bat Page for this week's Carnival of Space #61.
