  • Astrobiology ~ Exobiology; Life Beyond Earth ...

    EXCERPT:

    Astrobiology is the study of the origin, evolution, distribution, and future of life in the universe: extraterrestrial life and life on Earth. This interdisciplinary field encompasses the search for habitable environments in our Solar System and habitable planets outside our Solar System, the search for evidence of prebiotic chemistry, laboratory and field research into the origins and early evolution of life on Earth, and studies of the potential for life to adapt to challenges on Earth and in outer space.[2] Astrobiology addresses the question of whether life exists beyond Earth, and how humans can detect it if it does.[3] (The term exobiology is similar but more specific — it covers the search for life beyond Earth, and the effects of extraterrestrial environments on living things.)[4]

      Mystery 'noise' could be an Earth-like world: Strange signals suggest habitable planet exists 22 light years away

      • Gliese 581d planet looks similar to Earth in both size and temperature
      • Found in 2010, it was later dismissed as stellar bursts and not a planet
      • Now, scientists believe the earlier analysis was based on inaccurate data
      • They say planet does exist and may be our best hope for finding alien life

        The recent discovery of the two new planets, Kepler-438b and Kepler-442b, reveal that small habitable-zone planets does exist.

          Astronomers claim that thousands of such "Goldilocks" worlds exist...but none in our remote sector of the galaxy.

            This one looks promising....


            A world called Gliese 832c is also potentially habitable — and it lies just 16 light-years away, a mere stone's throw considering the vast scale of the universe.

            Astronomers found Gliese 832c, which also orbits a red dwarf, using three different ground-based instruments. The exoplanet is a "super Earth" at least five times as massive as Earth, its discoverers say. While Gliese 832c may be habitable, it could also resemble scorching-hot Venus, whose thick atmosphere has led to a runaway greenhouse effect.

              16 lightyears is totally inaccessible to us for now and the foreseeable future.

                Is there any planing going into the first interstellar probe.

                  There is a theory that they may well have been numerous civilisations located on distant planets that advance to a certain stage of development before self-destructing, which is why we have received nothing in the way of a communication from afar.

                  A lesson for us, perhaps ?

                    Ether that or the survivors have a policy of non communication for safety reasons.Looking within our own past an understandable policy.

                      With our current level of technology sending a probe just 16 light years away would take about 30,000 years at a minimum to get there (about 100,000 kph... About double what Voyager 1 is doing...)

                        I was thinking more along the lines of the payload,which should be ready long before the delivery system,say when we can get to the low hundrds of years for the delivery system.

                          Tardigrade

                          Look forward to seeing these on a planet near you...

                              Alpha Centauri Earth-like Planets

                              Making the closest star(s) even more a focus for first interstellar missions (once such are possible);

                              Two Earth-like planets could be hiding close to our solar system - and scientists say there may be watery worlds nearby

                              • Planets may be close to other habitable worlds 4.3 light years away
                              • The first planet, dubbed Alpha Centauri Bb, was discovered in 2012
                              • But it was quickly dismissed by scientists who said it was a false alarm
                              • New analysis used Hubble data instead to find some signals from the planet, as well as a second one close by
