The Carnival of Space #4 is now up at Universe Today, and is well worth a look to find out what a wide range of writers are saying about everything from terraforming Mars to the linkages between science and science fiction. Ian Musgrave’s Astroblog offers good background on GJ 436 b, and I particularly like Universe Today‘s own take on a story we’re currently featuring about the expansion of the cosmos. Lots of new reading here, and busy readers will appreciate the selection process that singled these items out. A sharp editor is a godsend for the information-deluged.
