Place the Solar system in our Galaxy

Planet Earth, the Solar system . and all the stars visible to the naked eye are in the milky Way Galaxy . which is a spiral galaxy with a jumper with two distinct sleeves starting at the ends of the jumper.

This was confirmed in 2005 a space telescope named the Lyman Spitzer, which showed that the centre bar of our galaxy is larger than previously thought. Spiral galaxy barred spiral galaxy barred (“bar”) of bright stars emerging from the center and crossing the galaxy in the middle. Spiral branches in these galaxies begin at the ends of the crosspieces, whereas in normal spiral galaxies, they come directly from the kernel. Observations show that about two thirds of all spiral galaxies have a bar. According to existing hypotheses, the jumpers are centers of star formation, supporting the birth of stars in their centers. It is expected that through orbital resonance, they are passed through a gas of spiral branches. This mechanism provides a flow of building material for the birth of new stars. Milky Way along with the Andromeda galaxy (M31),Triangle (M33), and more than 40 smaller galaxies-satellites, form the Local Group of Galaxies, which, in turn, is part of the Virgo Supercluster. “Using infrared images from NASA Spitzer telescope allowed scientists to discover that the elegant spiral structure of the milky Way has only two prevailing sleeves from the ends of the Central bar of stars. Previously it was thought that our galaxy has four main hoses “. 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 history of cosmonautics

Space and Humanity

History of Astronautics – 098

The history of the space a number of times when on the road to further human exploration of outer space rose up high and seemingly insurmountable barriers. In 1961 the transition to weightlessness caused in perfectly healthy astronaut a painful condition similar to motion sickness. In 1966, after a three-week flight on the satellite “Cosmos-110” slightly alive returned to Earth two dogs. In 1970 it became clear that the meeting with Earth after 18-day stay in weightlessness is very difficult for humans. So there was a barrier of reparations, and the possibility of longer flights required further justification. In 1978, after a three-month flight is in the blood of an astronaut found atypical forms of erythrocytes, which suggests the appearance of weightlessness in a new generation of abnormal formed elements. In recent years, in connection with the implementation of the 7-8 series record-month flight appeared ideas about qualitatively new changes in the condition of the body in the postflight period, although not everyone agrees specialists.
