What the comet was approaching the Earth

Events

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

Planet in February 2016

In February, continuing a run of parade of the five planets – mercury, Venus, Saturn, Mars and Jupiter lined up in the morning sky. In early February, their background will be the sickle of the waning moon, and by the middle of month two of the five planets will become unavailable for visual observations of mercury and Venus, disappearing into the rays of the rising Sun. Jupiter is in its best appearances in 2016. Uranus and Neptune gradually complete its visibility in the evening sky. The sun moves through the constellation of Capricorn, February 15, passing in the constellation of Aquarius.

The moon will come together with these planets: 1 February when the lunar phase is from 0.5 to Mars, on 4 February when the lunar phase 0.2 to Saturn, on 6 February when the lunar phase is 0.08 – Venus and mercury, 10 February when the lunar phase 0,03 – with Neptune, on 13 February when the lunar phase 0.25 and with Uranus, on 24 February when the lunar phase 0,97 – with Jupiter. For observations it is better to choose nights when the Moon is near the full phase passes close to the observed planet. Continue reading

Future technology

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
