Space is beautiful and very amazing. Planets revolve around stars that die and go out again, and everything in the galaxy rotates around a supermassive black hole slowly sucking in everything will come too close. But sometimes space throws up so much weird things that you twist your mind into a pretzel, trying понять это… 
Photo from Open Source Red Square Nebula Objects in outer space for the most part is very rounded. Planets, stars, galaxies and orbit shapes – everything resembles a circle. But the nebula Red Square, an interesting-shaped gas cloud, hm, square. Of course, astronomers were very, very surprised, because the objects in space should not be square. 
Photo from open source In fact, this is not quite a square. If you look carefully at the image, you will notice that in across the shape is formed by two cones at a point contact. But then again, there are not many cones in the night sky. The hourglass nebula glows very brightly, as in at its very center is a bright star – where it touches cones. It is possible that this star exploded and became supernova, causing the rings at the base of the cones to become glow more intensely. Collisions of galaxies In space, everything constantly moving – in orbit, around its axis or just rushing through space. For this reason – and thanks to incredible power attraction – galaxies collide constantly. Perhaps you are not surprise – just look at the moon and understand that space loves to keep small things near large ones. When two galaxies containing billions of stars collide, local disaster, right? 
Photo from open sources In fact, in collisions of galaxies the probability that two stars collide is almost equal to zero. The fact is that in addition to the fact that the cosmos itself is large (and galaxy too), it is also itself quite empty. Therefore his and called “outer space.” Although our galaxies and look solid in the distance, don’t forget that the closest to us the star is 4.2 light years from us. This is very long away. Pillars of Creation As Douglas Adams once wrote, “space is big. Actually big. You can’t even imagine you can, how breathtakingly large it is. “We all know that the unit of measure for distances in space is light year, but few people think about what this means. A light year is such a great distance that light is something what moves fastest in the universe is this distance only for a year. 
Photo from open sources This means that when we look at objects in outer space that are really far away, like the Pillars of Creation (formations in the Eagle nebula), we look back in time. how so it turns out? Light from the Eagle Nebula reaches Earth in 7000 years and we see her as she was 7000 years ago, because what we see is reflected light. Consequences of this drop in the past is very strange. For example, astronomers believe that Pillars Creations were destroyed by a supernova about 6,000 years ago. I.e these Pillars simply no longer exist. But we see them. Problem Horizon Cosmos is a continuous mystery, wherever you look. For instance, if we look at a point in the east of our sky and measure radiation background, and then do the same thing at a point in the west, which will be separated from the first by 28 billion light-years, we see that the background radiation at both points is the same temperature. It seems impossible because nothing can move faster than light, and even light would need too much time to fly from one point to another. How could microwave background stabilize almost uniformly throughout the universe? 
Photo from open sources This may explain the theory of inflation, which suggests that the universe spanned long distances immediately after the big bang. According to this theory, not the universe formed by stretching its edges, and itself space-time stretched like chewing gum in a split second. In it an infinite short time in this space the nanometer covered several light years. This is not against the law that nothing can’t move faster than the speed of light because nothing and moved. It just expanded. Imagine the initial the universe as one pixel in an editing program images. Now scale the image with a factor of 10 billions. Since the whole point consists of the same material, its properties – including temperature – are homogeneous. How black a hole will kill you Black holes are so massive that the material begins to behave strangely in close proximity to them. One can imagine that being drawn into a black hole means spend the rest of eternity (or spend the remaining air), screaming hopelessly in a tunnel of emptiness. But don’t worry, monstrous gravity will rob you of this hopelessness. 
Photo from open sources The force of gravity is stronger, the closer you are to it to the source, and when the source is such a powerful body, values can seriously change even at short distances – let’s say the height of a person. If you fall into a black hole with your feet forward, the force of gravity acting on your legs will be so strong that you will see your body stretch into spaghetti from lines of atoms that draw into the very center of the hole. You never know, suddenly this information will be useful to you when you want to dive into the womb of a black hole. Brain cells and Universe Recently, physicists have created an imitation of the beginning of the universe, which began with the Big Bang and the sequence of events, which led to what we see today. Bright yellow cluster densely packed galaxies in the center and the “network” of less dense galaxies, stars, dark matter and other things. 
Photo from open source large-scale structure model Cosmos At the same time, a student from Brandis University investigated the relationship of neurons in the brain by examining subtle mouse brain plate under a microscope. Image he received, contains yellow neurons connected by a red “network” compounds. Doesn’t resemble anything? 
Photo from open source Brain neurons Two images, although they differ greatly in their scale (nanometers and light years) are strikingly similar. What is this, a common case of fractal recursion in nature, or the universe really represents brain cell inside another huge universe? Missing baryons According to the Big Bang theory, the amount of matter in the universe will ultimately create enough gravitational attraction to slow the expansion of the universe to full stop. However, baryonic matter (what we see is stars, planets, galaxies and nebulae) is only 1 to 10 percent of all matter that should be. Theorists balanced the equation with hypothetical dark matter (which we can’t observe) to save the situation. 
A photo изopen source Every theory that tries to explain the strange absence of baryons remains with nothing. The most A common theory is that missing matter consists of intergalactic medium (dispersed gas and atoms floating in voids between galaxies), but even with this in mind, we still have mass of missing baryons. So far we have no idea about where is most of the matter that should be on really. Cold stars That stars are hot, no one no doubt about it. It is as logical as the snow is white, and two by two is four. When visiting a star, we would be more worried about how not to burn, and not how not to freeze – in most cases. 
A photo from open sources Brown dwarfs are stars that very cold by star standards. Not so long ago astronomers discovered a type of stars called Y-dwarfs that represent the coldest subspecies of stars in the family of brown dwarfs. Y dwarfs are colder than the human body. At a temperature in 27 degrees Celsius, you can easily feel such a brown dwarf, touch it, if only its incredible gravity will not turn you into porridge. These stars are damn hard detect because they emit virtually no visible light, so you can only search for them in the infrared spectrum. They go even rumors that browns and Y-dwarfs are the very same “dark matter” that has disappeared from our universe. Problem solar corona The farther the object is from the heat source, the colder. That’s why it is strange that the surface temperature of the sun is about 2760 degrees centigrade and its crown (something like its atmosphere) 200 times hotter. 
A photo from open sources Even if there may be any processes, which explain the temperature difference, none of them can explain so much difference. Scientists believe that this somehow connected with small inclusions of the magnetic field, which appear, disappear and move along the surface of the sun. Since magnetic lines cannot intersect each other, blotches are rebuilt every time they fit too close, and this process heats the crown. Although this explanation may seem neat, it is far from elegant. Experts cannot agree on how long these inclusions live, without saying About the processes by which they could heat the crown. Even if the answer to the question lies in this, no one knows that makes these random inclusions of magnetism generally appear. Eridan’s black hole Hubble Deep Space Field is image taken by the Hubble telescope, which captured thousands distant galaxies. However, when we look into the “empty” space in area of the constellation Eridanus, we do not see anything. At all. Just black a void spanning billions of light years. 
Фотоfrom open sources Almost any “voids” in the night sky return images of galaxies, though fuzzy, but existing. We have there are several methods that help determine what can to be dark matter, but they leave us empty-handed, when we look into the void of Eridanus. One controversial theory speaks of that the void contains a supermassive black hole around which all nearby galactic clusters rotate, and this high-speed rotation combined with the “illusion” of expanding the universe. Another theory says that all matter someday stick together together to form galactic clusters, and drift voids form between clusters over time. But this does not explain the second void discovered by astronomers in the south the night sky, which this time is approximately 3.5 billion light years wide. It is so wide that it can hardly be explained even the big bang theory since the universe did not exist so long that such a huge void could take shape by ordinary galactic drift.
