Inside the comet 67P found no major voids

Interested in everything connected with high technologies.

Inside the comet 67P/Churyumov — Gerasimenko there are no large voids. The mission of “Rosetta” the European space Agency made measurements that clearly demonstrated and solved the old mystery. Comets are icy debris left over from the formation of the planets 4.6 billion years ago. Spacecraft have visited a total of eight comets, and through these missions we pulled a picture of the basic properties of these space-time capsules. On some questions the answers were found, others appeared.

Comets, as we know, consist of a mixture of ice and dust, and if there were compact, gravity superior to water. However, previous measurements have shown that some of them have very low density, much lower than water ice. Low density means that the comet must be extremely porous.

But what is this porosity: due to large voids in the subsurface of the comet, or due to a more homogeneous structure with low density? Continue reading

Galactic tourists

100 kilometers above the Earth’s surface (according to the international standards space begins at this altitude), speed – kmh 4000, which is 4 times the speed of sound, so it looks like a tourist flight into space, which you could see in sci-Fi movies or dreamed about since childhood.

Now the dream to see the immensity of outer space has already become a reality.

Who are those 5 people who first saw the Galaxy, read the article. We will also talk about the details of the flight and to quote the impressions of space explorers.

This reckless American with a decidedly non-American name proudly bears the title of “space tourist No. 1”. Anthony Tito is a multimillionaire and entrepreneur of Italian origin. Continue reading

Comet Churyumov-Gerasimenko may be inhabited by alien microbes

Comet 67P/Churyumov-Gerasimenko which is travelling now in the company of the device of the probe Philae and Rosetta could be inhabited, according to The Guardian . According to scientists, testifies to this rich organic compounds black crust of the comet.

According to leading astronomers, its presence can be explained by the presence under the ice crust “of microbes-extremophiles”, able to adapt to the harshest conditions. Similar microbes surviving in extreme conditions in the most inhospitable corners of our planet.

Previously, Rosetta also found a strange accumulation of organic matter, particles reminiscent of viruses.

However, as scholars have noted, neither Rosetta nor Philae is not equipped to directly detect life – then, 15 years ago, when preparing the project, according to astronomer and astrobiology Chandra Wickramasinghe of, over such a proposal would only laugh. Continue reading
