Earth creatures migrate to Titan planet?

Scientists have come up with a hypothesis, whereby some microbes on Earth may have safely migrated to the Titan asteroid, a moon of Saturn in the solar system.

About 100 blocks of soil from Earth fall to Europa

It is possible that the blocks of rock fired from the earth after a historic collision with meteors 65 million years ago brought life to Titan. Earth microorganisms in rock fragments thrown away from this Earth's mother can germinate the organic matter-rich life.

At a conference on Earth and Moon that took place in Houston, USA, scientists believe that the crash of a giant space rock eradicates the dinosaurs so strong that it makes the blocks of rock. The earth could hit Titan.

According to calculations, for the blocks of rock to bring microorganisms to live away from the Earth safely, the cosmic rock must collide with the Earth at a speed of 10-50 km / sec. That was justified by the computer after measuring a hole of 160-240 km is believed to be a vestige of the other collision on the Yucatan Peninsula, Mexico.

Million years journey

Brett Gladman from the University of British Columbia (UBC) and colleagues calculated that as many as 600 million pieces of rock flew out of the Earth and flew into the orbit of the Sun from a horrific stab. Some of the hundreds of millions of such rocks probably fly to the orbit of Saturn and Jupiter. The two asteroids Titan and Europa of these two planets are most interested in cosmologists.

The latest exploratory results show that Titan has enough organic compounds to provide energy for the first life forms. And Europa only contains seawater below the dense ice.

Dr. Galdman's team estimates that about 20 blocks of rock from Earth reach Titan. They fly into Titan's atmosphere at a speed of 10-15km / sec, a speed small enough for the creature in these blocks to remain after a solid journey for about a million years until it lands on the surface. Titan.

With Europa, the situation doesn't look as good. The possibility of up to 100 blocks of rock flies to Europa. But Jupiter's gravitational force is so strong that the other blocks of rock are accelerated to 25km / sec and crash into Europa's surface at a speed of 40km / sec. Calculations on computers show that, with such a landing speed, simple life-like amino acids on rocky soil are severely damaged.

The unanswered question is whether cold temperatures on Titan will be able to grow. This new finding reinforces the hypothesis that life on Earth is seeded as well as Titan.

It is meteorite pieces or dust on the comet that brings life from some distance in the vast universe to bring to Earth the first life forms from which they flourish to this day.
