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:

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

Martian Chronicles

“It is good to wonder, said the philosopher. Space travel has again made children of us all”.

To be very brief and concise, that I sometimes even work, then advise, as it is a brilliant creation that deserves repeated reading.

To be a little chatty, and allow yourself to speculate about the book, we can’t help but notice, what I like about it, absolutely everything – from the atmosphere of the text, the storyline in General and how it builds up the narrative of the book. Yes. This is not a novel, or solid piece. The story is built through short stories related to each other not how much the main characters, and how the very idea that revolves around the red planet, Mars.

But she’s great as written. As these stories fascinate the imagination. How bright the picture turns out before my eyes. if you’re in the rocket, which is sent to a dark and unknown planet Mars.

I don’t want to be objective, but from me not require, right? After all, I write a review. And feedback means transfer THEIR feelings and experiences. So I couldn’t understand people who wrote negative reviews about a boring story. I can’t understand my friends who believe this book is one of the weakest ideas of the author. Continue reading
