Edmund Halley opening date

Discoverer: named after Edmund Halley opening date: 1758 (first predicted perihelion) Alternate designations: comet Halley (Halley), 1P Orbital characteristics: Age: 2449400.5 (17 February 1994) Aphelion: 35.32.e. Perihelion: 0.586.e. The semi-major axis: 17, 8 and.e. The eccentricity repulsed: 0, 967 Orbital period: 75, 3 and the Inclination of the orbit to the Ecliptic plane: 162, 3 degrees Last perihelion: 9 February 1986 Next perihelion: 28 July 2061 g the Period of revolution around the Solar system: from of 74.4 to 79.2 years. The average value of 76 years. Thanks to a successful “visits” in 1986 to comet Halley spacecraft “VEGA-1 and VEGA-2” (USSR) Giotto (ESA), “Suisei” and “Sakigake” (Japan) scientists got the first pictures of the core and comprehensive information:

Unique comet

Leaving the Oort cloud, the Earth is approaching comet Catalina, consisting of primordial matter.

Comet C/2013 US10 Catalina has completed journey around the Sun and is now approaching Earth. The comet will fly at a distance of 108 million km from the planet. It can be seen with the naked eye or in binoculars 17 January 2016 in the area of the constellation URSA major, reports Global Science .

The comet opened in October 2013 with the help of automated search system, which was developed under the project called the Catalina Sky Survey, providing a view of the sky.

C/2013 US10 is one of the many comets are in the Oort cloud, located at a distance of 50-100 thousand astronomical units.

Experts believe that the cloud is material left from the formation of the entire Solar system.

The first Catalina circled around the Sun took place at the end of November. Now the comet can be observed in the constellation of Virgo, however, this requires special optics. Continue reading

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
