Comets of the centuries

In the fall of 2020, after Amateur astronomers Vitaly Nevsky and Artem Novichonok first observed the comet ISON, astronomers had expected that she would become a “Great comet” − a rare visitor, perhaps the brightest comet of the twenty-first century.

Alas, severely battered during the close approach to the Sun in November of this year, ISON no longer promises such a bright future. To the naked eye from the Ground to see it would be impossible − but hopes not worth it to lose. Somewhere in the dark depths of space, probably unnoticed by anyone else is racing the comet, which will deserve the attention and present us with an unforgettable sight. This has always been the Large comets appear about once a decade, and every century one of them was especially bright.

Comet ISON

We will tell you about these “comets of the century”, since the sixteenth century. It is interesting that they flew as a rule, in the second half of your century, and has had an average of once every 97 years. Given this, we can calculate that if the comet of Ikeya-Seki (C/1965 S1) visited the Earth in 1965, following a visitor, you can wait until 2029.

However, to predict what particular impossible: a Big comet can appear quite unexpectedly, at almost any time. The message we may hear tomorrow.

There is a space of 40 Nations

Recently the world celebrated the first 50 years of human space flight. And now, after half a century, this date should be remembered, because in space, traveled more than five hundred people from many countries, including from Ukraine.

Fidel Pavlenko said Oleg Fedorov, Director of the space research Institute of NAS of Ukraine, whether to continue to consider, on 12 April an outstanding day in the history of mankind?

Space activity is not profitable. It is of course. But we understand that there is a space of 40 Nations with a space program, and even in the crisis public investment has not decreased, as far as I know. This suggests that many countries consider that such activity for us today it’s not profitable, but, as the Americans say – investing in the future.

It seems to me that every civilized man, who forgets the beginning of its activities or the activities of its predecessors, not like this. So one who is engaged in space activities, even for him this is not only a celebration, an occasion to reflect every time on what you do today, what path was and what is waiting for you. Therefore very important for us because this date is once again to think over the strategy. Continue reading

Astronomers have discovered a ninth planet on the outskirts of the Solar system

While it “calculated” on the computer

In 2006, the Solar system lost one of the nine planets — Pluto stripped of planet status due to negligible size. But the discovery of American scientists threatens to return the ninth planet in the system — found a new celestial body, claiming the title.

The staff of the California Institute of technology Michael brown and Konstantin Batygin has published a paper in the reputable scientific journal “Astronomical journal” about his study, in which they “discovered” a new planet in the Solar system.

Celestial body has a mass of 5-10 times larger than our planet, and is about 20 times farther from Earth than Neptune. Despite the fact that Neptune is the most distant planet, until it 4300 million kilometers. Accordingly, before “the ninth planet” – about 8600 million. The problem is that open planet. while no one was looking through a telescope, it was discovered through computer simulation. However, the accuracy of such simulations is very high today.
