Periodic Comet

Periodic comet attracted by the Sun, sent to him, but pass due to the same sensitivity to the solar wind, which causes the surrounding cloud of dust and gases blown away from the Sun. People believe that the tiny particles of solar wind will impact more than large particles, but this assumption is wrong. If this were so, then how to explain the continued existence of the Asteroid Belt, which includes debris of any size is not affected, apparently, by the solar wind. The small object may lose velocity faster than the larger object because of differences in gravity, but if they are sensitive to solar wind, it occurs the same effect, – they are repelled equally. The comet, which (eventually) reach the Sun, with a very repeatable trajectory around the Sun, losing a lot of water vapor so that the ratio of substances in their composition is aligned at the expense of pushing away by the solar wind. In short, they lose their cover. They fly up with acceleration from the external space, but at this time do not change direction, going outside, and face (with the Sun). In fact, comets complete their orbits, coming nearer in the process, getting closer and closer to the Sun. Continue reading

Philae probe is similar to a cat?

Matt Taylor – the adventures of Rosetta

Caught the comet British astrophysicist Matt Taylor told the guests of the festival 360° about the Rosetta mission. about why study comets in General, and about their own role in this Grand project. We have selected a few interesting quotes from Kinot-speech for those who for some reason missed the lecture or watched the broadcast.

About comets in General

I will tell you about their history, about their view on what the Rosetta mission, because I am only a small part of a huge team. So why do we study comets?

This film, created by Polish Studio Platige Image jointly with ESA] was released shortly before docking of the probe Philae from the comet. Its task is to explain the purpose of our mission. We hope to learn more about the evolution of the Solar system – where did we come from? Therefore, it is important to understand how on Earth there was water.

Here’s what we know about comets after all observations. Their Central core is very small if to compare with the “tail” of dust and gas that the comet emits. Continue reading

Martian Chronicles

“It is good to wonder, said the philosopher. Space travel has again made children of us all”.

To be very brief and concise, that I sometimes even work, then advise, as it is a brilliant creation that deserves repeated reading.

To be a little chatty, and allow yourself to speculate about the book, we can’t help but notice, what I like about it, absolutely everything – from the atmosphere of the text, the storyline in General and how it builds up the narrative of the book. Yes. This is not a novel, or solid piece. The story is built through short stories related to each other not how much the main characters, and how the very idea that revolves around the red planet, Mars.

But she’s great as written. As these stories fascinate the imagination. How bright the picture turns out before my eyes. if you’re in the rocket, which is sent to a dark and unknown planet Mars.

I don’t want to be objective, but from me not require, right? After all, I write a review. And feedback means transfer THEIR feelings and experiences. So I couldn’t understand people who wrote negative reviews about a boring story. I can’t understand my friends who believe this book is one of the weakest ideas of the author. Continue reading
