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

The largest planet of the Solar system

The planet, which attracts the attention of scientists and astronomers, no less than Mars, is the largest planet in the Solar system and part-time older brother the rest of the planets. because Jupiter formed first after the big Bang, and subsequently helped other planets, including Earth, formed. Scientists say that it is thanks to Jupiter, the globe exactly what it is.

Jupiter is the fifth planet in distance from the Sun, to fly from Earth to Jupiter to take two years. He has 67 satellites, which by its position and rotation resemble a system of planets orbiting around the Sun. One of these satellites is of the greatest interest because of the possibility of the existence on it of life is a satellite of Europe. Jupiter attracts attention not only by its size but by the size of its satellites, because the biggest satellite of the Solar system is a moon of Jupiter (Ganymede) which is covered by lots of craters.

In addition, the largest planet of the Solar system consists of gas and liquid and there is absolutely no solid surface. The gas that makes up a planet by composition resembles the structure of the Sun. Continue reading
