Early Evidence of Life on Earth is the Moon

Knowing how life began on planet Earth is one of the main goals of science. Some British researchers have a new theory. They believe the key to know the mysteries of early life forms on Earth it was in the month.


Researchers say, the stones that come from planet Earth asteroid flew to the moon while bombarding the Earth and inner planets (the planet closest to the Sun) others.

For information, about 4 billion years ago, there was the phenomenon of a meteor shower called the Late Heavy Bombardment. At that time, the planets Mercury, Venus, Earth, and Mars bombarded by thousands of asteroids and meteorites that hit the planet's surface.

The phenomenon is very terrible that lasted 300 million years has varied effects on planets when it was young, one of which is hurling billions of tons of material from the surface of the planet into space.

In the case of Earth, most of the material was likely made it to the Moon. This hypothesis is plausible, given the Earth's south pole ever encountered a proven meteorite originating from Mars.

For that, it is possible to assume that the inner planets of material exchanged during Late Heavy Bombardment. Similarly, the Earth and Moon are also mutual exchange of material.

According to some experts from the University of London Birkbeck College School of Earth Sciences, Earth's material that has landed on the moon with a smooth, making it possible biological markers are saved properly.

Quoted from Softpedia, a research team headed by Ian Crawford and Emily Baldwin mentions, biological signs that it will not be able to survive on Earth because of the huge impact of a meteor collision, erosion due to wind and rain, volcanic activity, earthquakes, and control of habitat by other living species.

In a number of computer simulations, the team showed a hunk of material bouncing into the Moon on the Earth due to asteroid impact would land on the lunar surface with a speed of 2.5 kilometers per second or less. With temperatures on the Moon, no part of the material that is close to the peak pressure resulting material was melted.

Unfortunately, this new theory has not been proven scientifically until the man went back to the Moon, collect samples of rocks from a number of locations, and bring back to Earth for analysis in depth. However, such research will give us tremendous knowledge of the history of life on planet Earth.

Planet Parade Followed by Fireworks Festival Of Meteor Eta Aquarids

Alignment of six planets in a straight line in early May 2011 will be an interesting scene at dawn. Moreover, the events will occur simultaneously with a large meteor shower that originates from the constellation Aquarius. Planet parade will be followed by fireworks in the sky.


Astronomy researcher from Institute of Aeronautics and Space Agency (LAPAN), Thomas Djamaluddin, said Eta Aquarids meteor shower will occur in early May. At the peak, there were 60 shooting stars per hour. "Top of the meteor shower occurs on May 6, 2011 starting at 3:00 pm," he said.

Meteor showers happen when comet dust enter the Earth's atmosphere. Dust then bergesekkan with air to burn and produce light. Eta Aquarids meteor shower comes from the rest of the visit of Halley's comet dust sun once every 76 years.

As meteor showers, constellation Aquarius in the southeastern sky. Meanwhile, in the eastern region, four bright stars will be lined up to form a single line. The result, in the eastern sky we could see two rare phenomena as well as the parade of planets and a meteor shower. "The show looks beautiful until sunrise."

The four bright planets, namely Venus, Mercury, Mars, and Jupiter, is above the horizon since at 4:50 pm. Meanwhile, the two planets are much fainter, that Uranus and Neptune have been published since the early days.
