Possible discovery of a new super-Earth orbiting Proxima Centauri

It was big news in 2016 when astronomers discovered a planet orbiting Proxima Centauri (PC), the nearest star to our sun.

That planet, named Proxima b, is potentially habitable, and at the time, there was speculation that we could send a robotic explorer there in only a few decades.

The lead author of this study is Mario Damasso from the INAF Astrophysical Observatory of Turin, Italy.

They think they can send a nano-spacecraft with cameras to within one AU of the planet and return images much more detailed than we can hope to achieve with any telescope.
