Other Life in the Universe

Other Life in the Universe

Are we alone?

We have been in doubt if we are alone in the universe for a long time. Since the mid-20th century, that is why, this speculation became science itself. "Exobiology" trying to determine the conditions necessary for life and a place that allows developing, and using the technical tools that may allow us to put it.

Drake Equation
In 1961, an American radio astronomer, Frank Drake, the theoretical equations proposed to estimate the chances of the existence of intelligent life in our galaxy. Formula that he thought the subject of discussion. The objective is to calculate the amount of communication civilizations that might exist in the Milky Way and a reasonable expectation to receive the signal.








The equation is N = (R *) x (FP) x (Ne) x (Fl) x (Fi) x (Ft) x (L)

• R * said the rate of star formation in which the culture develops possible. This number is a fraction of all stars in the galaxy with the exception of giant stars that have a life too short time for the emergence of civilization communications.
• Fp is the fraction of stars that have planetary systems
• Ne the number of planets similar to Earth, located in the zone which covers a support formation conditions of life.
• Fl equal to the fraction of planets where life could develop.
• Fi Fraction expressed Fi planet where life has reached the stage of intelligence.
• Ft is the fraction of civilizations that have developed technology that allows them to send signals into space.
• L states when living civilization that can send radio signals that can be detected
• N the number of civilizations in Milky Way communication that can send radio signals that can be detected. This amount varies depending on the value used for each parameter in the above; result stems from 1 (our civilization) to millions or even billions.

Traces of life on Mars?
In 1996, found traces of a meteorite micro fossils from Mars. Long micro fossils resembles bacteria on Earth. It is estimated that falls in the Antarctic meteorite 13,000 years ago, but has been crystallized 4.5 billion years before the march, when the planets formed. Micro fossils is certainly alive when the Mars is warm and humid. Dry riverbed on Mars is the remainder of the time when the planet has a climate that supports life.











Message for Extraterrestrials (Aliens) In 1974, Arecibo radio telescope has been send a message in binary code form to the globular clusters in the Hercules constellation, consisting of hundreds of thousands of stars, which will reach 25,000 in the year.

Algae and Fungi that can be Eaten

Algae and Fungi that can be Eaten

Different Texture and Taste

There are about 25,000 species of algae, but only about 50 are good to eat. Aquatic Algae are often called vegetable from the sea. Japan is a producer, exporter, and the largest algae consumers. This explains the many names in Japanese algae. More than 100,000 species of fungi are known, only 20 types of fungus that can be cooked. Between 1% and 2% of species are toxic, causing serious problems, even death and can not be eaten. Others have the texture or taste.

Algae Algae have the texture and taste which are very diverse. Some are elastic, the other a soft and dry. They are used as food, seasoning, decorator, and supplements. Algae are composed of as many as 40-60% carbohydrate. They are also good sources contained minerals, including calcium and iodine. some cultivated algae, pieces of algae that carry the spores grown on the tube or rope plsyik in the reservoir with sea water temperature is set or in the sea.

• Once under water, forming a branch of hijiki dry noodles
• Nori is orange algae that became black when dry, thin leaf of nori used to make sushi.
• Jelly is a material extracted from red algae, thawed, used to make jelly that can replace gelatin in some recipes.
• Spirulina Algae is a microscopic protein, usually eaten as a supplement food .
• Lettuce Algae Sea looked and tasted like lettuce.

Fungi Groups of fungi including mushrooms tribe, but also mold and yeast used to make cheese, bread, beer, etc.. several species of mushrooms such as button mushrooms are cultivated. technique consists of miselia spur to develop the natural or synthetic fertilizers (made with straw, bark, gypsum or other materials) or wood. Some mushrooms are eaten raw, but generally must be cooked.

• Velve foot, which is very popular in Asia, has a thin veil and a long stalk.
• Button mushrooms, widest and most popular power.
• Truffles are extremely rare below the surface.
• Morel, hood covered the alveoli, can only be eaten if cooked properly.

The Origin of the Earth

The Origin of the Earth

Formation and evolution of our planet

Five billion years ago, our solar system does not exist. There is only a cloud of dust and gas that is slowly changing shape. Nine planets, including Earth, formed from the clot material, resembling a ball of snow, in fog.

1. The process began about 4.6 billion years ago in the solar nebula center.
2. The sun formed at the center of this cloud. Meanwhile, gas and other materials on the outside began to clot.
3. Small stones into a large, forming the embryo of a planet, or a protoplanet, with a diameter of several kilometers.
4. Protoplanet each other collide with each other and agglomerate until they reach the size of the planet (having a diameter of several thousands of miles). Up to hundreds of millions of years, the planet is bombarded by a strong and continuously by other rocks.
5. About 4.5 billion years ago, Earth was blanketed by a sea of lava that comes from the burning rocks and wide reach several kilometers.
6. Gradually, the lava lake cooled crust forming continuously hit by meteors and comets.
7. Our young planet also experienced by the volcanic activity which releases a radical atmosphere, the atmosphere is different from the current atmosphere. Possible existence of water comes from the depths of the Earth, or taken from space by comet and form a sea. At the same time, the Earth's crust into the continent.
8. The emergence of continents, oceans, and low oxygen levels result in the formation of more complex molecules, which led the creation of extraordinary phenomena, namely life. Even more astounding, life was very quickly emerged from the sea, less than 1 billion years after Earth was created. Life requires a few billion years to reach the mainland.
