The largest planet

People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.

Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.

It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.

To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading

The cost of a flight into space

In technological terms, the human life is becoming more interesting: XXI century people can tolerate a lot of people couldn’t even conceive of at least two centuries ago. Fifty years have passed since the moment when man first flew into space – and now there is such a thing as space tourism. See with your own eyes on top of our planet is no longer something magical and unrealistic – the question is, what is the cost of space flight.

The man tightly on the Ground

Man and humanity as a community of individuals peculiar passion for travel, for change of place of residence. There are different opinions as to what are the roots of this passion. Romantics say about innate human curiosity, a constant desire to learn something new, to look beyond the horizon.

Rationalists believe that the desire for constant movement is an echo of the primitive instinct of survival. Primitive man, being the least protected in terms of wildlife and lack of civilization, was required to constantly move to avoid danger and to find new sources of food. Continue reading

The largest planet of the Solar system

The planet, which attracts the attention of scientists and astronomers, no less than Mars, is the largest planet in the Solar system and part-time older brother the rest of the planets. because Jupiter formed first after the big Bang, and subsequently helped other planets, including Earth, formed. Scientists say that it is thanks to Jupiter, the globe exactly what it is.

Jupiter is the fifth planet in distance from the Sun, to fly from Earth to Jupiter to take two years. He has 67 satellites, which by its position and rotation resemble a system of planets orbiting around the Sun. One of these satellites is of the greatest interest because of the possibility of the existence on it of life is a satellite of Europe. Jupiter attracts attention not only by its size but by the size of its satellites, because the biggest satellite of the Solar system is a moon of Jupiter (Ganymede) which is covered by lots of craters.

In addition, the largest planet of the Solar system consists of gas and liquid and there is absolutely no solid surface. The gas that makes up a planet by composition resembles the structure of the Sun. Continue reading
