Kepler 22-b is the first confirmed exoplanet which orbits it's host star within the 'habitable zone'. What will this mean in the search for extra-terrestrial life? Could this planet be Earth 2.0?

  • I feel like in the far future, you'll just be able to sit down at a machine and it'll say "If you like EARTH, you may also enjoy _________, ______ and _______!" Then it'll ask if you want to try it out, like iUniverse.

  • @Morphesque That would be SO COOL! Even if it's just a simulation, that would be awesome. I think you should start work on such a machine :-P

  • While 600 light years is still out of reach (for us in our current technological state), all of this information is paving the way for future discoveries and advancements. It may feel like baby steps for us, but this will lead to leaps and bounds for the future of humanity. And in astronomical numbers, 600 light years is practically next door. Onward and upward with curiosity, experiment, and adventure. This first step is very exciting indeed. :D

  • @nihonjenn In the next couple of years, exoplanets will be coming thick and fast. In turn, we'll be learning a whole lot about our own planet :-)

  • Neat! I think scientist need to spend more money on learning more about earth than a planet we cannot reach.

  • @Oty3d a very good point, the vast majority of Earth remains an unexplored mystery :-) But, since we are viewing these exoplanets millions of years in the past, by studying them we can learn about the formation of planets like our own, other solar systems, the conditions for life etc. We may not reach it, but there's a lot to be learnt by looking :-)

  • Nicely explained, thank you.

  • Good vid but your facial expressions are way too anyoying

  • @rossexton Exactly

  • @JisouPHased 600years if we are going at the speed of light...

  • @FindMeInKurume thank you!

  • @DarKnightofCydonia I totally forgot about time-dilation! We'll just have to fold spacetime & create a wormhole instead :-P
