Good omens in the search for antique life on Mars

Structure in the meteorite ALH 84001.The tiny piece of carbon found in meteorites from Mars were formed by the cooling of volcanic emission, were not left there by ancient space germs. This is good news and bad news for astrobiologists.

The discovery in 1996 of carbonate structures in the meteorite ALH 84001, which traveled from Mars to Earth 13,000 years ago, was hailed at the time as evidence that extraterrestrial microbes have ever lived on the Red Planet. However, further studies of both the carbonate structures as tiny bits of macromolecular carbon (MMC) in the meteorite cast doubt on those claims.

Jupiter

This is the biggest planet in our solar system; its group is double that of the other planets mutual. Because of this Jupiter cause visible change in their peers in the solar system particularly on Mars, Saturn and largely asteroids and comets.

The destruction of the planet is about 1/16 (so-called dynamic flattening) it is connected to the high speed of revolution. The Jovian revolution period is the straight in the entire solar system and although not all parts turn at the same average speed is 10 hours. In 1961 there was a variation on this for more than a second.

Pluto

Number of satellites: 1 the most important, 2 very small discovered by the Hubble Space Telescope in 2006.

The story of Pluto, its discovery

For Adams and Le Verrier, Neptune was the solution. For generations of astronomers who followed would become a problem.
