I found out about it yesterday, from Paul Gilster's blog, Centauri Dreams.
It had all the right information:
- Link to the new Wikipedia page
- Obligatory homage to Stephen Baxter's SF novel Proxima (so accurate!)
- Reference to Yuri Milner's Breakthrough Starshot project.
The key question: observe it better with giant space telescopes (maybe a new push for the FOCAL mission using the sun as a gravitational lens) .. or send a probe?
Might a country (the US or China, say?) embark upon a high-prestige, multi-decade-long programme to send such a mission?
It encounters that old starflight paradox: the later launches - so much more technologically advanced - overtake the first ones.
I think it's possible that the youngest children on Earth might live to see close-in imaging of this planet .. and/or a mission that we might have figured out by then how to slow down.
