No shortage of space related material in the blogosphere today, that’s for sure. First, the news that the design of Hubble’s replacement, the James Webb Telescope, is being tweaked to allow it to be serviced by remote drones while in orbit – hence (hopefully) avoiding the technical issues that have plagued the Hubble for the last year or so.

Next, Centauri Dreams reports on the discovery of a multi-planet star system that could throw the established theories of planet formation out of the window.

And there’s masses more, thanks to Universe Today hosting the 4th Carnival of Space blog carnival. If you don’t know what a blog carnival is, it’s a blog post that links to a whole load of other specially-written posts in the same subject area. It’s also a great way to kill a few hours!
