Proxima Centauri, closest star to our Sun, as seen by Hubble
A planet has been discovered orbiting Proxima Centauri located about 4.24 light years away. Proxima Centauri is a red dwarf and is about 15% as bright as our local star the Sun. Interestingly, the planet found is located in the theorized habitable zone of the star.
Technologies are very close that would allow man to travel at nearly 20% light speed enabling us to visit this star within a 20 year timeframe. As a reference, the Voyager probes were launched in the 70s and we would be receiving pictures of the planet by now if they had interstellar technology at that time.
Here is a summary of current & theoretical space technologies:
The most fascinating (to me) is the last one referred to as the "Alcubierre Warp Drive". Basically a caterpillar drive that generates a warp bubble to travel.
Anyway, I found it extremely interesting that we found a potential solar system that we absolutely will be exploring sometime this century. I hope I live to see it!
