Although much is known about the cosmos, the knowledge accumulated throughout the centuries of human history is a tiny part of what there is to know. Stay here to know some of the most interesting facts of space (of what scientists already know, of course)
1. The Moon’s Removal – The Moon is gradually moving away from Earth at a rate of 3.8 centimeters per year. This spacing also affects the rotational movement of the Earth, which every 100 years slows down by two milliseconds.
2. A cloud in space– Finding water in space is not the most likely things. However, there is a large cloud of water vapor that contains 140 times the mass of water in the oceans. Located about 10 billion light-years from Earth, this cloud is actually a quasar emitting water vapor rather than sucking it.
3. The nearest black hole – The closest black hole to Earth, and known to scientists, is Cygnus X-1, about eight thousand light-years from Earth. Surprisingly, only 14 black holes are known throughout the universe.
4. Ice harder than steel– The temperatures on Pluto are extremely cold, about minus 200 degrees Celsius, which is not very surprising given the distance from the Sun. The most curious fact is that ice on Pluto is So compact because of the low temperatures it becomes stronger and harder than steel.
5. Cold Starts – Although the vast majority of stars produce large amounts of light and heat, brown dwarfs do not have enough mass to start the hydrogen fusion process, which releases heat and imparts the characteristic brightness of stars. A brown dwarf in particular, WISE 1828 + 2650 has a surface temperature of only 26.6 degrees Celsius.
6.Foundation in space– When trying to join two pieces of metal on Earth it is necessary to resort to the casting process, which uses heat to melt the metals. However, in space this process occurs naturally. Initially, NASA thought the process was instantaneous, but later realized that for two metal surfaces to merge it is necessary to join them and press for a while.
7. Burping impossible – Burping is a banal activity for the inhabitants of the Earth, since gases separate from liquids and food in the stomach. In space, however, the existing gravity is too slow for liquids and gases to separate, which makes belching impossible.
8. A galaxy with several galaxies – As we all know, the solar system is situated in the Milky Way. What you may not know is that our galaxy has at least 15 – possibly more – smaller satellite galaxies around it. This group of galaxies is known as Local Group.
9. The smallness of the Sun – The Sun is a large star, but it is not so great when compared to other stars of the universe. VY Canis Majoris is a supergiant located 4,900 light years from Earth and has a radius two thousand times greater than the radius of the Sun. If VY Canis Majoris were the star of our solar system, all the planets up to Saturn would be swallowed by its lightning.
10. Are you afraid of the dark? – Despite the great advances made in the field of astronomy and astrophysics, scientists have not yet solved the mystery of black matter and black energy. In fact these two terms are used to refer to all phenomena and bodies that the scientific community has not yet uncovered.
