AGI) Berlin - A sensational discovery was made by German and American astrophysicists who detected a planet similar to the Earth. It is 22 light years away. Professor Guillem Anglada-Escude, who teaches in Goettingen, explained that this planet is likely to contain water and possibly even life like the one we know. The new Super-Earth has a volume 4.5 times greater than that of our planet; it makes one revolution every 28 days around its own sun, which is much smaller than the Earth's. Steven Voigt, from the University of California, who made the discovery together with his colleague from Goettingen, said that the discovery of this planet makes us believe that our galaxy is full of billions of planets that are potentially inhabitable. . .

If you go there, you're going to weigh 400kg. You wouldn't even be able to move. If humans evolved there, they would be 30cm tall.

Of course that would be assuming it's made largely of the same sort of materials, and the density is roughly similar. Otherwise, life would even be more dissimilar with ours.

The phrase "life as we know it" is a term which should translate to "water/carbon based life".

how do you calculate all that?

Erm ... you're right. Wrongly.

Forget what I said earlier.

The first thing is we need to define the concept of life. In paralel to this effort, we need to identify the events and processes that took place in our planet which triggered the life building process. Similar process should have taken place somewhere else or may currently be happening. It is also important to consider its spin for the existence of magnetic field, its mass and gravity to help secure an atmospher. If a planet has these basic conditions it will be a good candidate for further studies.
