Life is to be found where there is an asteroid belt

Rebecca Martin of the University of Colorado at Boulder, and Mario Livio of the Space Telescope Science Institute in Baltimore, developed a rather wasteful theory suggests that, for the formation of life on Earth in the solar system should positively be an asteroid belt, and stringently, where it is now.

Observations exoplanetary systems show that the so-called warm dust, which, apparently, the result of asteroid is concentrated in areas close to the "snow line." This may be because it was her form giant planets; the light elements are not able to condense on the surface of a celestial body, whether it is closer to the Sun.

The future belongs to microbes

The last form of life on Earth would fall by 2.8 billion years, the sun burned dying - red giant. About a billion years before the only living things on the planet will remain single-celled organisms, hiding in isolated hot and salty waters.

This gloomy prognosis for life on Earth, but a ray of light for those who are looking for life on other planets. After thus renewed hope its discovery in places previously considered inhospitable.

Panspermia: Origin of life on Earth?

The probability of Panspermia

Microorganisms that crashed on Earth surrounded in distant body parts could have represent the seeds of life according to research by Princeton University, the University of Arizona and the Center for Astrobiology (CAB) of Spain.

Does the meteorite that brought the instructions for life on Earth?

Some think that meteorites brought indispensable materials for the beginning of life. A meteorite discovered in Antarctica would give strength to the argument that life on Earth may have started due to a boost from space, scientists say. The analysis shows that the meteorite is rich in the gas ammonia. Contain the element nitrogen, found in proteins and DNA that form the basis of the life as we know.
