Around the Solar system

Top 5 for the day

Automatic interplanetary scouts NASA, the European space Agency and others currently collecting information about our Solar system. Right now the spacecraft are in orbits of Sun, mercury, Venus, Earth, Mars, and Saturn, flying to other small space objects.

Thanks to the astronauts and to all automatic mechanical scouts in space, we have the opportunity to see “family” Photos of our Solar system.

Recover in the journey.

For a start look at our Earth. It looks like Moscow, when the ISS passes over the territory of Ukraine, February 2, 2015. Scientific evidence indicates that Earth formed from the solar nebula about of 4.54 billion years ago. Presumably life appeared on Earth about 3.9 billion years ago, i.e. during the first billion after its occurrence.

So it looks from space, the Salt flat of Uyuni — dried salt lake in the South of the desert plain Altiplano, Bolivia at an altitude of about 3 650 m above sea level. The inner part is covered with a layer of salt thickness 2-8 m During the rainy season salt marsh covered with a thin layer of water and turns into the world’s largest mirror surface.

What the comet was approaching the Earth


A small comet Hartley 2 will be visible from Earth with the naked eye, on 20 October, when she will fly past the planet just 11 million kilometers. Over the last century, this will be the closest “contact” of our planet with a comet.

Hartley-2 was discovered in 1986. Its orbital path was far from the Earth, while the couple spins around Jupiter do not orbit drew closer.

Hartley-2 will be included in the number of comets that passed in the last century is quite close to the Earth.

Comet McNaught (McNaught) lit up the sky in 2007. Becoming the brightest comet in over forty years, McNaught was dubbed the great comet of 2007. The astronauts were able to observe this comet, resulting in Strait light on the composition of these celestial bodies. spacecraft Willis found here the decrease of the solar wind.

The comet’s discoverer, Australian astronomer Robert McNaught (Robert McNaught) was discovered in 2009 a new bright comet McNaught C/2009 R1 . flying past Earth in June of this year. Continue reading

What engine will go to the stars?

I must say that the problem of space distances increasingly asserting itself. Chemical rockets on its effectiveness has exhausted itself for the future. Even the nearest planets of the Solar system on them to fly extremely long. Nuclear space engines while not in orbit, but on paper. Ion on a large scale. The spacecraft with solar sails will be valid only within the Solar system.

What engine to fly to the stars and how? After all, even with a nuclear engine will take flight for decades and centuries! Why? Because, according to theories, it is impossible to exceed the speed of light. And by estimations of astronomers, the nearest star to Earth with exoplanets (a planet similar to earth) is at a distance of 13 light years.

It is about exoplanet Kapteyn b, which is presumably suitable for life. For those who do not know: for light year, the astronomers believe the distance that a beam of light passes in our earth year at the speed of 300,000 kilometers per second. Other discovered exoplanets: Gliese 832c (16 light years), Gliese 667 Cc (22,7 light years), Kepler 186f (500 light years), Kepler 62f (1200 light years). But on a normal ship flight to the nearest star to us (alpha and Proxima Centauri – the distance in four and a half light years) will take time-75 thousand years. Of course, not light, but ordinary, earthly years. Continue reading
