This is from the foundation that put out the announcement, Pale Red Dot.

A lot of difficulties, but the best thing put forward, is that if an earthlike planet is circling the closest star, that they should be relatively common.

And the Breakthru Starshot meeting just over, and this system is still a good target, but not the only one.

and they did some modeling of the dust abrasion on the wafer probes, most won't make it.

Developing Ecospheres on Transiently Habitable Planets: The Genesis Project

This is a human panspermia project, for encouraging life on a planet that was sterilized early, but now in a livable phase.

and a paper on atmo detection, by looking for temperature albedo and whether tidal locking heat distribution is measurable. Looks like a yes, when JWST is up there.

and this one shows a thin atmo is enough to distribute heat to the darkside http://astrobiology.com/2016/08/tutorial-models-of-the-climate-and-habitability-of-proxima-centauri-b.html
