Scientists: the ninth planet in the Solar system — 500-ton piece of ice
The ninth planet has a mass of 10 Earth masses and is moving strongly forward on a bizarre elliptical orbit around a hot star. …The discoverers of the planet are unable to observe firsthand the ninth element of the Solar system, but scientists using mathematical and computer simulation calculated the trajectory of the most distant planet.
Scientists have shown video of the new ninth planet of our galaxy
Yet due to the insufficient capabilities of optics, it is impossible to see this mysterious object. Astronomers still argue that the chaotic motion of some space objects in the Kuiper belt indicates the presence of “the ninth planet”.
New planet: scientists have uncovered details
“Ninth planet” — so scientists call this mysterious object, which has so far failed to see due to lack of opportunities of modern optics, according to “BBC Ukraine”. Continue reading
In the new year period in December 2015 on the horizon we can observe the double-tailed comet Catalina C/2013 US10 Catalina.
Information, data, interpretation of the significance of the comet Catalina.
Astronomical, cosmopolitisme and mythological content of the comet Catalina.
Comet C/2013 US10 Catalina.
Good news for all lovers of the starry sky — comet C/2013 US10 Catalina two weeks ago passed perihelion, the closest approach to the Sun, and now flies back to the depths of space. Until January 17, Catalina will approach closer and closer to the Ground, and in the first weeks of December, the sky in the middle latitudes it reaches the maximum sky brightness. This is a great chance to watch the comet live — even more so that the next time Catalina will be visible only after a few million years. Continue reading
One of the major negative biological factors of outer space, along with gravity, is radiation. But if the situation with the gravity on different bodies in the Solar system (e.g. on the moon or Mars) will be better than the ISS, with radiation, things are more complicated.
On the origin of cosmic radiation is of two types. It consists of galactic cosmic rays (GCR) and heavy positively charged protons emanating from the Sun. These two types of radiation interact with each other. In the period of solar activity, the intensity of galactic rays decreases, and Vice versa. Our planet is protected from solar wind by the magnetic field. In spite of this, some of the charged particles reaches the atmosphere. The result is a phenomenon known as the Aurora Borealis. High-energy GCR almost stopped by the magnetosphere, but they do not reach the Earth’s surface in dangerous quantities due to its dense atmosphere. The orbit of the ISS is above the dense layers of the atmosphere, but inside the radiation belts of the Earth. Because of this, the level of space radiation on the station is much higher than on Earth, but substantially lower than in the open space. Its protective properties of the Earth’s atmosphere pribliziteljny 80-cm layer of lead. Continue reading
