Are some planets more habitable than Earth ?

Astronomers seeking signs of alien life are on the lookout for 'superhabitable' extrasolar planets.
In the hunt for habitable alien worlds astronomers have been particularly keen to look for signs of planets that exhibit similarities to our own, but now astrobiologists have suggested that what we should be looking for are planets that are even more habitable that the Earth is.

"From a potpourri of habitable worlds that may exist, Earth might well turn out as one that is marginally habitable, even bizarre from a biocentric standpoint," wrote researchers René Heller and John Armstrong who put forward the idea.

A 'superhabitable' world would most likely be older and larger than the Earth, while water and gases most commonly associated with signs of life ( such as oxygen ) should also be present. Planets located more towards the center of their sun's habitable zone might also yield a higher potential for habitation than those, like the Earth, that lie near the edge.

No Humans = More Habitable

No Humans = More Habitable Venus has no humans but I wouldn't call it more habitable

Like spacecowboy says ... this one is the one we are adapted to. If we could colonize a planet with the right atmosphere and climate ,full of fruit and nut trees and prolific edible plants with fresh water springs everywhere (hot and cold) we'd probably sicken and die because of unfamiliar bacteria or such.

We should be trying to discover new means to travel by bending space or so called worm holes. It is the only way. Conventional speeds , even light speed won't help through meteorite fields. Higher speed in space can easily became uncontrollable.

All they've been finding lately are really large planets, orbiting closely around smaller stars. That bias is due to the current state of our technology. So they are trying to fluff up the findings that they have so far.

Its not our technology that prevents us from deep space travel, it is our political-economical system who s holding back the progress. If we had followed the evolution further that started in the 30ties we already would have colonies on Mars for decades. If you see what the Nazi's have acomplished, as a single country, in hardly 2 decades we would even be further. But the money is controlled by a small group of people who are constantly use it to manipulate our economical system for personal gain and control. In fact its our political system who allows that. Democracy in its current form is si... [More]

Show me a planet where the air isn't polluted with the stupidity of the human race and I will show you a habitable planet.

Lets just hope that we take better care of them if we do inhabit them. -stevemagegod has a point
