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
At the end of last week in Ulyanovsk has started an interesting project Simple science. Its initiator is the teacher of UVAU HA Leonid Podymov.
— The main purpose of my lectures is to educate. I would like to tell Ulyanovsk on the latest and most interesting achievements in modern science into simple language so that it is clear even to the unprepared listener, — says the organizer of the “Simple science”.
Leonid physicist by education, so the project is focused mainly on natural Sciences. In particular, the first lecture was devoted to astronomy — or rather, cosmic distances and scale.
— Many people know that, for example, our Solar system is big. But it is actually an ordinary person is unlikely to adequately represent these scales and distances — simply because it is not something to compare. I tried using a few simple techniques to bring clarity in such comparisons, says the teacher.
So, during the speech he invited the audience to spend with him a few thought experiments.
— Let’s imagine that our planet has shrunk to the size of a standard basketball ball whose radius 12.2 centimeters. If we reduce all other razmery accordance with a given scale, we get the following illustrative figures: the Sun will be a ball with radius 13 meters. Continue reading
At the science Museum in London opened a major exhibition “Cosmonauts: Birth of the space age”. It was to be the culmination of the cross year of Russia and great Britain, but now the British authorities have given guarantees for the return of Russian exhibits. Including artifacts that have never left the walls of private enterprises: the Soviet space ships, outfits, and archival documents. Tickets for the show sold out two months in advance.
This moment in London waiting for: when the world’s first woman astronaut will come to the machine in which it 52 years ago, spent almost three days, circling above the Earth.
“It’s such a faithful and reliable friend, by which without emotion could not be disregarded. And in the training center, when I meet him, every time I try to pet him and say “Hello!””, – says Valentina Tereshkova.
Spacecraft “Vostok-6” was never exported outside of Russia – like most of the exhibits of the exhibition dedicated to Soviet and Russian achievements in space exploration. A significant portion of what is now presented in the London Museum of science, and even Russia have seen a few. Continue reading
