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
People were engaged in agriculture in the stone age, 30 – 35 thousand years ago. This is evidenced by the notches on animal bones and rocks, cave paintings. This is, perhaps, the earliest “scientific notes”, in which the authors noted the different phases of the moon and count days and nights.
Monitored by our astronomical instruments, the universe consists by weight of about 76 percent hydrogen and 23 helium. Only slightly more than one percent accounts for all other elements of the periodic table.
It is estimated that the galaxy contains more than a hundred and twenty billion stars and to represent its enormous size, we will give one comparison: if the path from the Sun to Earth light travels in 8 minutes, the diameter of the galaxy it will for a hundred thousand years.
To show the progress made over half a century in the study of the Universe, astronomer Paul Couderc came to a startling comparison. Suppose that all known astronomy to 1900 area of the Universe displayed on the plan area of one square meter. Continue reading
It happened because of that. the density of gases inside of it are incredibly low. Actually, in our Galaxy the number of stars is estimated at least 200 billion. White ovals on Jupiter limited circumferential zones. however, they can interact and form a region of chaotic clouds. On the Photo from a Space telescope named Hubble. made in ultraviolet rays. auroras appear as an annular zone around the poles of the planet. At the very least. its atmosphere is mostly hydrogen. The picture is composed of images. cameras made by Galileo using three filters. and shows. how it will look ancient rotating system of clouds. if you fly right over her. Most people go to work in the office. but my dream is to work at home.
Can you believe it. that many centuries ago.
The largest planet in the Solar system — Jupiter.
The largest planet of the Solar system The largest planet of the Solar system is.
Pluto is a planet or not. it was formulated the concept of determining Liberona the sky recently, a completely new object, a reddish point. which is very weakly visible. And that is what the scientist William Herschel was able to determine the rotation period of the planet. Instead of the Sun in our Solar system or somewhere on the outskirts. where it will not be visible. However by weight, it is second largest planet in three times. Continue reading
