Space topics are one of the most interesting to study these days. True, there is still not enough financial resources for full-fledged research of the Universe, however, the available equipment allows to some extent to study something and build hypotheses, which, within the limits of our solar system, at least, can sometime, in the very distant future, even be confirmed by becoming axioms. Powerful telescopes and a variety of automatic spacecraft give a chance that even though the surrounding space environment within the Oort cloud, we will be able to understand and determine its laws in the next twenty years. If this succeeds, then there will be less fears for all these asteroids allegedly falling to the Earth and other universal threats so beloved by some individuals.
In particular, not so long ago there was an interesting publication that, possibly, there could be water on Ceres, the largest planetoid in the asteroid belt beyond Mars. Scientists are interested in what walls are in fresh craters on a given celestial body. They are similar to those that are visible on an asteroid called Vesta, and also very similar to what is happening on our neighbor Mars, where there was water for sure, which has long been proven.
According to experts, the nature of such patterns indicates that the water under the surface evaporated quickly. Researcher Hanna G. Sizemore argues that this terrain is a clear general morphological marker, indicating that the site is or has been humid. There may be ice deposits, and this knowledge can be used in the future in order to study the possibility of the existence of life on asteroids in the past, as well as their full-fledged research - when mankind even comes to this.
By the way, not so long ago, experts have determined in general how water can behave in outer space. According to scientists, basically, this chemical compound there is either vapor or a semblance of ice mantles, which are fixed on interstellar dust grains. The reason is the very low density of outer space, which prevents the formation of water in a liquid state. In general, such a study is very important, since it brings closer to understanding how star systems and even entire galaxies were born.
Thanks to improvements in telescopes, scientists are now able to trace the transition of water in ways that have not been possible before. According to recent analyzes, such processes are especially noticeable when molecules begin to emit light faster, bumping into infrared photons. The latter form when supermassive black holes grow or new stars form in extreme numbers. This occurs most often in some conditionally dusty clouds, where the particles almost completely absorb optical light, subsequently heating up and emitting heat in the infrared range.

Another interesting "water" observation directly concerns our Earth. According to theories, such a chemical compound could have formed on the planet in the course of relatively natural processes, but now experts say that everything was somewhat different. Water could be delivered to Earth by comets along with xenon and various noble gases.
Such conclusions were made after studying the data collected by the COSINA spectrometer, which "flew" through the tail of the Churyumov-Gerasimenko comet, as well as when it approached it. The bowels of this celestial body contained xenon, and light isotopes prevailed over heavy ones. Accordingly, it could have entered our planet precisely through some comet crashing into the Earth, in an amount of at least 23 percent. There is, in addition, the likelihood in general that ice in the "tailed" celestial bodies was formed when the solar system was not yet formed. Then you can understand why comets also have a lot of free oxygen with sulfur, and also how it happened that in the Earth's oceans there is a strange amount of heavy and normal hydrogen.
In general, the formation of water and the search for it in space partially indicate not only the desire to understand how everything happens and happened in the past, but also the desire to answer the well-known question - are we alone in the Universe or not? Logically, if somewhere there is a corresponding chemical education, then life there could develop in some way. In the end, the first creatures on Earth appeared precisely in water, which gives a chance for the discovery of some intelligent races in other conventionally oxygen-hydrogen worlds. This will make it possible to understand whether all sorts of luminous and blinking points and ovals hanging in the sky are UFOs or clouding of minds of different personalities, somewhere in the depths of their souls infected with "alien hysteria", or, in general, someone's incomprehensible intrigues. At the same time, various theories will be refuted or confirmed aboutthat somewhere in the solar system someone can live.
Recently, ufologists have been especially stressing that some aliens may come to us from Mars. After a semblance of a dome was seen on the next picture of the Red Planet, some alien experts said that it was not just some strange hill, but a pyramid through which some locals enter a whole underground city.
Actually, this version turned out to be unsubstantiated, primarily due to the parallel research of other scientists, who determined that there are substances in the soil of Mars that act on living beings in a toxic way. We tested this opinion on a certain bacterium, which is characterized by a very high survival rate in almost any conditions. The latter died just a few minutes later. Accordingly, what then can we say about more developed and intelligent beings? What kind of Martians can there be in such conditions? The answer suggests itself.
