Billions of Planets Might Be Habitable

Billions of Planets Might Be Habitable

European researchers made a rather jaw-dropping announcement recently after studying the frequency of rocky planets similar to Earth in the habitable zones around faint red stars. They said the result of their study is there are tens of billions of planets similar to Earth.

The researchers studied 102 red dwarf stars over a six year period and found nine Super-Earths, which are planets with the same mass of Earth or up to ten times greater. Based on studying various data sets they concluded the potential number of inhabitable planets resembling Earth is huge. Super-Earths are thought to be very common around other stars and they could have both water and rock.

They found about forty percent of red dwarf stars have Super-Earths orbiting in a zone where it is possible water exists on the surface of planets.

Red dwarfs are the most common stars nearest the Sun, but are not visible with the naked eye due to low luminosity. It may be possible in the future to build a telescope that can view the light from an extrasolar planet to see if it shows signs of oxygen or methane. These two gases are chemical signs of life.

Always intriguing this line of thinking and nothing too surprising given the expanse of the universe, other galaxies and other endless possibilities.

There are those who firmly believe that since we have messed up this planet we have no right to travel elsewhere. The probability exists that there are countless species on other worlds who have done the same to their own home world but will eventually or already have begun space exploration themselves.

Then there are those who state that it will never ever happen, impossible and please focus on the realities on this planet. Of course humanity was told that we could never fly, it was impossible to cure this or that and countless other examples. The Earth is flat and that is that.

Given the fact that it is not any time soon that humankind will be able to do any large scale space travel or colonization of our solar system let alone remote far flung vistas, I would not spend much time lecturing about the evils of mankind and what we will do to neighbouring solar systems. Assuming we survive our current destructive path we may well evolve to a point where we are not a blight on the universe.

We may well one day travel elsewhere only to be consumed by the giant insectoids of planet Preyingmantoidalpha as a tasty snack. A human buffet table. Or perhaps the Borg will get us yet. Assimilated. Resistance Is Futile. Who knows? This process is just another Adventure In the journey of humankind. Maybe we will meet a speci

Too continue with the comment below since Care2 does not do a twitter style word count to warn us when we are getting to the cut off point of our comment---

Maybe we will meet a species whom will bring benefit to us all. The universe being vast and far flung as it is we won't really have to worry about travelling very far too soon. We have trouble affording gas prices as it is let alone warp engines.

There of course may well be aliens amongst us already watching us or in the process of using us to no good (or if an optimist-good) end. Only the march of Time will tell. Until then, gaze into the starry night for those of us lucky enough to still be able to see them untouched by the light of cities and towns and wonder!

Interresting, but all these planets are too far away for any of us to ever be able to visit.

Yes, let's save our home, Earth!
