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
Space tourists have already bought vouchers from Roscosmos for millions of dollars, which means that interplanetary travel ceased to be only a figment of the imagination of science fiction writers. Mankind has realized at last that the earth’s resources ischerpaemy, and set his sights on the conquest of the territories on a much larger scale and very different properties. There will be dozens or hundreds of years, and prepapre…our great grandchildren, perhaps when meeting have to introduce myself, “Hey, Hey, I’m from Earth. We got such a strong gravitational field, and there’s somehow easier to breathe”.
Interesting development in this area is the space Elevator, which will allow you to run in a cargo space without using rocket equipment. For the first time this thought Konstantin Tsiolkovsky, and in the twenty-first century NASA is already funding the development of this project. In the future it will be cheaper than building the missiles the media.
In fact, it must be a cable anchored to the Earth’s surface on a moving vessel at one end and the other adjacent to the space station, fixed stationary relatively to the planet. Continue reading
The period of rotation around the Sun
Of 11.86 earth years
The first “date” earthly messenger with the giant of the Solar system – Jupiter was held in late 1973. Still on approach to Jupiter by “pioneer 10”, began to transmit color images of the planet Earth. On the screens in the mission control Center dynamic unfolding panorama of the approaching giant striped. Bright stripes on Jupiter are like ridges over high and cold clouds. And Vice versa: the dark stripes are the valleys between the ridges. Among the atmospheric lanes of the South tropical zone “blazed” the bright colors of the famous Great Red Spot.
Further large-scale image of this amazing education received by “Voyager-1” (the highest resolution on the images was 5 km), allowed us to understand the complex meteorology of Jupiter. It turned out that the mysterious spot has a clearly visible vortex structure: this is a floating disturbance in the atmosphere, in other words, a huge atmospheric vortex. In the spot, there is a rise of the substance and spreading it from the center. Continue reading
