The best pictures of space and stars
The huge airless space is not so dark, boring and empty, as it may seem to an outside observer. On the contrary, many interesting facts about space show that this is not so! Most astronomical objects represent a real find for researchers. And while scientists continue to make great discoveries, we can only observe. And yet - to join the amazing information that changes the usual ideas about the world.
The existence of cosmic smells mankind learned only through modern equipment. Of course, these devices have no smell. But they have instruments for spectroscopy, allowing to classify different substances. The thirty-meter radio telescope, for example, managed to find two organic molecules in the gas clouds of the Galaxy. The first, n-propyl cyanide, is "responsible" for fragrant shades of rum, the second, ethyl formate, is for the taste of raspberries.
Some of the bodies of the universe have a naphthalene flavor, others have ethyl alcohol, some have citrus, and some have bitter almond. Such interesting facts about space are explained very simply. This is due to the ether compounds, hydrogen cyanide and other substances that have odors on Earth. But the surface of the moon, according to astronauts, gives a caustic powder. The nature of this phenomenon is associated with silica particles. That he is in large quantities contained in the lunar dust.
The speed of the Milky Way is 300 km / s. Our planet moves inside the galaxy, developing a record 230 km / s. The globe revolves around its own axis and goes around the Sun, which also rotates continuously. And if we go further and take into account the main tenets of Einstein's theory of relativity, movement at different rates changes the passage of time. In simple words, the acceleration of the first phenomenon leads to a slowdown of the second, from the perspective of an outside observer.
The famous "thought experiment" logically follows from the previous paragraph, because interesting facts about space cannot be avoided without controversial theories. A twin who crosses outer space in a ship moving at the speed of light will return to his younger counterpart when he returns home. Check this is unrealistic, although something similar can be observed even in our everyday life. A striking example is the time difference at the poles and the equator. People in the most northern and southern points rotate a little faster, and their clock speed is also accelerating, even for a few nanoseconds.
In the open airless space, there are fascinating laws of physics. In such exotic conditions, any metal objects in contact form a coherent whole. A similar effect is associated with the movement of particles, which are firmly connected in a discharged void. But can spaceships stick to each other? This is excluded, because every centimeter of plating is covered in advance with special substances.
He was discovered in 2004, adding interesting facts about space to another striking discovery. An impressive magnitude crystal has been found to be 50 light-years distant from the sun. He is a star of BPM 37093 from superdense carbon. Its diameter is 4 thousand km, and the core contains 10 quintillion carats. At the same time, the jewel of the universal scale is so ancient that it is the same age as the Milky Way.
The alcohol substance, known as Sagittarius B2, covers about 463 billion km. It contains gases, dust and methanol vapors. Of course, such alcohol is not suitable for drinking. However, it also has its own value, since it sheds light on the mechanism of formation of stellar matter, allowing scientists in the future to find out something else interesting about space. In addition, methanol is an intermediate link in the chain of synthesis of complex organic molecules, which are found in large numbers on our planet.
The size of a huge gas sphere is 300 thousand light years. It's almost like the diameter of the Milky Way, multiplied by three. The perfectly symmetrical shell is filled with ionized substances and dust. Inside it is a burning star 20 times larger than our star. Under the influence of the stellar wind, the Bubble Nebula continues to grow, expanding at 100,000 km per hour.
Some interesting facts about space destroy myths. For example, almost everyone knows that light travels a distance of 93 million miles to reach Earth. For this, it takes about 8 minutes, which is why many mistakenly measure the age of photons by some four hundred seconds. In fact, their energy originated much earlier - in the very depths of the nucleus. They spent more than 30,000 years making their way from the center to the surface.
This is actually asterism. In fact - the well-established name of the group of heavenly bodies. It denotes only part of the body and tail of the Bear. And the latter is not limited only to the Bucket: it has as many as 125 stars. In addition, in the constellation there are a lot of galaxies and even several exoplanets.
The most interesting thing about space is that mankind has yet to find out - especially if the information concerns mysterious intergalactic vacuums. So far only fragmentary data is known about them. Many people know that even sunlight cannot penetrate a black hole. Thus, according to the logic of things, it should not be seen at all. But no - astrophysicists constantly observe this phenomenon and even fix it on the photo. This is made possible by burning meteors and luminous clouds of gas that are sucked into a giant trap.
In outer space, more than a few hundred billion galactic systems. True, you can see only a few of them in the night sky. With a successful set of circumstances, Small and Large Magellanic Clouds are visible from New Zealand and Australia, which merge with the Milky Way. But the population of northern latitudes opens another amazing sight - the Andromeda Nebula. This galaxy from a distance resembles a small spot of light the size of a third of the lunar disk.
Interesting facts about space can be the basis for fantastic stories. In particular, scientists have established that the famous gas giant will not drown, even if it is placed in a hypothetical glass filled to the brim. Its density (687 kg / m3) is almost two times less than that of water (997 kg / m3). As a result, it will stay on the surface, without even touching the bottom. However, no one has yet been able to test the viability of this theory.
The remaining 5% are black holes, galaxies, stars, planets and other objects. Mysterious substance has mysterious physical properties. To determine its exact nature is not possible - at least with the existing scientific and technical base. As the researchers suggest, the substance does not have an electromagnetic charge. Thus, the very fact of its existence contradicts the known laws of physics.
This is caused by the phenomenon of tidal friction, due to which the Earth satellite moves slightly. However, experts do not consider such interesting facts about space as a sign of the apocalypse and are in no hurry to raise panic. The removal process will not be endless. Our night luminary simply does not have enough strength to "escape." The maximum that can happen is that its circulation period will increase one and a half times. And one should expect in a few billion years.
Even in those moments when we forget about the existence of outer space, it continues to remind of itself with various surprises. Every day about 10 tons of star dust and 5-6 tons of fireballs, meteorites or micrometeors (totaling 200 thousand) pour on us every day. No exception and man-made debris, which also enters the atmosphere. This includes fragments of old stations and wreckage of ships. Thus, the Earth noticeably "recovers", increasing its mass.
Experts managed to find out something else interesting about space. What happens on Titan is very similar to the early stages of the development of the globe. Now there are both a dense atmosphere and a stable liquid. True, the air consists only of ethane, methane and nitrogen, and the local rivers are not at all "sour" - they contain methane, an ethane liquid. At the same time, the average temperature indices are 170-180 degrees, which does not prevent astronomers from searching for the simplest forms of life in underground reservoirs.
