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
Astronomers at the Australian national University has discovered the largest known planetary systems. Therein, except for the Central star has a large planet.
This planet makes a complete revolution around the sun in nearly a million years. This gas giant is at a distance of one billion kilometers from the star, which exceeds in 140 times the distance between Pluto and the Sun. Reported by the BBC.
Thus far, there are only a few of these planetary systems.
The exoplanet, which received the designation 2MASS J2126-8140 has a lot of 12-15 Jupiter. It was discovered in the programme of observations of young stars and brown dwarfs in the immediate galactic environment of the Sun. Astronomers came to realize that they see not two independent object at the same distance from the Sun is about 100 light years away, a planetary system.
“We were very surprised by the discovery of an object with such a relatively small mass so far from the Central star. Unlike Solar, this system could not occur from a huge gas-dust clouds,” says Dr. Simon Murphy from the Australian national University. Continue reading
