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

Humanity seems to have stayed in their home Solar system

In Houston there was a scientific conference on the most ambitious project of the century.

“Transition to transformation”

Humanity seems to have stayed in their home Solar system. Of his burning desire to go to other stars, scientists said at a scientific conference, held in October in Houston (Texas, USA). Experts discussed the most grandiose project of the century – “Centennial spaceship” (“100-Year Starship”, or 100YSS ).

– Despite all the technological advances of humans, in the field of space exploration we’re on the level of cave people, – assured the leader of 100YSS Mae Jamison. All we did was hang a station in earth orbit, where just sometimes come to live people. And also sent a robot to Mars, which only publishes Pictures in Instagram and writes in Twitter. The main task of space exploration in the long term should be the creation of colonies, which can live people. Continue reading

Top 10: huge space objects

Oceans, of course, is extensive, and the mountains are impressive for its size. 7 billion people is also not a small number. Since we live on planet Earth (whose diameter is 12742 km), it is easy for us to forget how we, in fact, tiny. In order to realize it, all we need to do is look into the night sky. Looking at it, it becomes clear that we are just a speck of dust in an unimaginably vast universe. The list of objects below will help to see the greatness of man in the future.

The largest planet (by diameter 142.984 km)

Jupiter is the largest planet in the Solar system. Ancient astronomers named Jupiter king of the Roman gods. Jupiter is the 5th planet from the Sun. Its atmosphere consists of 84% hydrogen, 15% helium with small admixtures of acetylene, ammonia, ethane, methane, and water vapor hospita. The mass of Jupiter is 318 times the mass of Earth, and its diameter is larger than the earth 11 times. The mass of Jupiter is 70% of the mass of all other planets of our solar system. The volume of Jupiter can hold 1300 planets the size of Earth. Jupiter has 63 known satellites (moons), but almost all of them are very small and dim.
