This is the theory that life is not merely a surface scum which clings to the outside of planet Earth, but that living things, in the form of so-called extremophile bacteria which can tolerate infernal heat, penetrate several kilometres into the planet's interior.
On the plus side, the ability to directly detect light from a planet closer to the size of Earth than a Jupiter-sized gas giant is a positive step forward in our ability to learn more about planets that might be habitable.
We know that Earth, which was spun off from the sun, is a planet with a beginning.
In a conference room, looking through a wall of glass into the Messenger mission-control center, Solomon described his fascination with the parched and moon-like planet, which is a sister of Earth.
The newfound world, dubbed Kepler-22b, is much bigger than our planet - but, even so, it's also the smallest world yet discovered outside our Solar System, and finding it does bode well for the eventual detection of a true twin, a planet that really is a second Earth.
Apple ( AAPL) is in this model, doing just fine trading in the orbit of Planet Earth worth about a half a trillion dollars.
It was discovered in 1986 and it takes a convoluted horseshoe path around our planet as it is tossed about by the Earth's and the Moon's gravity.
"Since the population of our planet keeps growing, and the amount of land on this Earth is limited, a more efficient, and more sustainable system of food production is needed, " Oonincx said in a statement.
However, the likelihood of such life developing is lower than that of a planet that could be considered more Earth-like.
FORBES: No, Scientists Did Not Find 10 Billion Earth-Like Planets In The Galaxy
It is intended to generate 80kN of thrust and is designed to place the Earth observation satellite into its final orbit just a few hundred kilometres above the planet.
They estimate that at least a third of the planet's mass is diamond - the equivalent of three times Earth's mass.
In contrast, the third Earth-like planet, Kepler 69c, orbits a star very similar to our sun (that is, hotter than Kepler 62).
As I have written about extensively, Silicon Valley is the top environment on planet Earth for fostering startups: So if you find yourself wearing the shoes of a Startup founder, and you are not in the Bay Area, you are operating at a disadvantage from day one.
If you go out from Earth up into space, you see our entire planet is a living organism - be it in the sea with all the fish, on the land with all the reptiles and mammals and insects, but the way man is behaving at the moment needs attention.
Kepler-22b is quite a bit larger than the biggest rocky planet in this Solar System (which happens to be Earth), but much smaller than the smallest of our local gaseous worlds (Neptune).
