50 very curious facts and scientific discoveries

Did you know that the largest galaxy discovered to date is the IC-1101, with approximately 100 trillion stars? And that the Milky Way is part of a gigantic cluster of 100,000 galaxies? Discover 50 very curious facts about astronomy, biology and other areas of science.

Did you know that If we make all of the atoms, people, planets, constellations and galaxies disappear, the universe will continue to weigh three quarters of what it did before – that is, 73% of its original mass will remain.

Did you know that If the Big Bang had occurred on January 1, the Milky Way would have risen on March 15 and the Sun would have risen on August 30.

Did you know that The largest structure in the universe is formed by a group of quasars fed by a massive black hole. It is so big that it would take 4 billion years to traverse it at the speed of light.

Did you know that A team of astronomers found an exoplanet – as planets outside the solar system are called – with a ring system 200 times larger than that of Saturn. Part of the material from these rings is aggregating and forming moons.

Did you know that The Milky Way and its neighbors are part of a cluster of galaxies called the Virgo Cluster. This, in turn, is part of a super cluster of 100,000 galaxies called Laniakea.

Did you know that The Milky Way is on a collision course with Andromeda, one of the nearest neighboring galaxies. Both are believed to clash in 3 billion years.

Did you know that The sun takes around 250 million years to make a complete turn in the Milky Way. Since the appearance of the galaxy about 13 billion years ago, it has only been around 54 times.

Did you know that If the sun were the size of a cell, the Milky Way would be comparatively the size of the United States’ territory.

Did you know that If we were to drive a car at a constant speed of 160 kilometers per hour, it would take about 221 million years to reach the center of the Milky Way.

Did you know that If you could drive your car upright, straight up, it would only take you an hour to reach space (which is around 65 kilometers).

Did you know that Contrary to what science fiction films show, it is impossible to hear the sound of a spaceship exploding in space. Reason: the sound does not propagate in a vacuum.

Did you know that The universe smells like hot metal, diesel smoke and barbecue smoke.

Did you know that Sunlight takes 8 minutes and 17 seconds to reach Earth. If it exploded at that point, we wouldn’t know for 8 minutes.

Did you know that The light of many stars takes thousands and even millions of years to reach us. If a star 15,000 light-years away explodes at that moment, we will only see that event 15,000 years from now.

Did you know that Every minute, somewhere in the universe, a star explodes and shines more than an entire galaxy.

Did you know that The famous red spot on the planet Jupiter is a 400-year-old storm. Detail: it is three times bigger than the Earth.

Did you know that There are 5 dwarf planets in the solar system: Pluto, Ceres, Éris, Haumea and Makemake. But the lineup of likely similar stars is immense, with more than 20 candidates. Some even received names: Palas, Hígia, Orco, Varuna, Vesta, Quaoar …

Did you know that The Earth rotates at 1,600 kilometers per hour, but it travels in its orbit around the sun at a speed of 107 kilometers per hour.

Did you know that When the Krakatoa volcano erupted in 1883, the force of its explosion was so great that it can be heard over 7,700 kilometers away in Australia.

Did you know that The largest volcanic eruption in history occurred 250 million years ago in what is now Siberia. It was responsible for the extinction of 96% of life on Earth.

Did you know that Of the approximately 90 chemical elements in nature, only 17 are responsible for all chemical reactions that occur in your body.

Did you know that Seventy percent of your body is pure water. Since water is mainly formed by hydrogen, it is the most common element in the human body. By the way, it is also the most abundant element in the known universe.

Did you know that In a period of 100 years, a water molecule spends less than a week in the atmosphere, 2 weeks in lakes and rivers, 20 months in the form of ice and about 98 years in the oceans.

Did you know that Only 2.7% of all water in the world is safe for consumption. If we put all the water on the planet in a giant bottle, the drinking water would be equivalent to one drop.

Did you know that An adult person loses around 15 grams of skin per day. Much of the dust in a house is made up of the skin of the people who live there.

Did you know that The hair grows about 1 cm per month. The curious thing is that they grow faster in summer and during the day than in winter and during the night.

Did you know that A person walks around 160 thousand kilometers during his whole life. This is equivalent to going around the Earth four times in a row.

Did you know that During the period of 1 year, the heart pumps no less than 262,800 liters of blood, which would give 26.5 tankers of 10,000 liters.

Did you know that People with more than 50 spots on their bodies are more susceptible to skin cancer. The greater the amount of spots, the greater the vulnerability of the skin.

Did you know that If it were possible to put all living beings on the planet on a scale, 80% of the weight would come from microorganisms – say viruses and bacteria.

Did you know that One of the most terrible parasites that exists is the amoeba Naegegleria fowleri. If a person dives into a swimming pool or lake with this type of creature, they can become infected and have their brain devoured by it.

Did you know that The smallest mammal in the world is the shrew, at just 10 centimeters. When it is born, it is smaller than a bee.

Did you know that The hyena is the mammal with the strongest bite. A hyena bite is capable of crushing its victim’s bones. It also has a gastric system that allows the digestion of bones.

Did you know that The animal that produces the most feces is the blue whale. A single whale is capable of producing 90 kilos of poop a day.

Did you know that According to the calculations of the WHO (World Health Organization), there are three rats for each person in the world. As the world population is 7 billion people, that gives 21 billion rats.

Did you know that More than 80% of animal research involves laboratory mice. Altogether, 90 million rats and mice die each year in scientific experiments.

Did you know that The hummingbird flaps its wings 90 times a second, four times faster than a dragonfly. It is also capable of flying backwards and upside down.

Did you know that Who came first, the chicken or the egg? Answer: the egg. Fish, amphibians and reptiles were already developing eggs before the first birds appeared.

Did you know that Crocodiles hardly develop infections. Their blood has a natural antibiotic that causes wounds to heal quickly.

Did you know that Sharks are able to smell a drop of fish extract within a radius of approximately 2,000 meters. They can also feel a drop of blood in 100 parts of water.

Did you know that It may seem strange, but the heart of the shrimp is in the head. In fact, not only the heart, but the whole digestive system of this animal is in your head.

Did you know that Spiders, mites, tattos and centipedes are not insects. Spiders and mites are arachnids, small fish are crustaceans and centipedes are kilopods.

Did you know that The largest colony of ants in the world is 6 thousand kilometers long, divides into millions of anthills and occupies the coast of ten European countries.

Did you know that The flies rub their paws to clean them. Paws have aroma and flavor receptors that need to be clean so that they can “recognize” new foods.

Did you know that The strongest animal in the world is the rhinoceros beetle. He can carry 850 times his body weight. the equivalent of a man carrying 75 cars on his back.

Did you know that Everyone knows that there are no elephants in Siberia. This northern region of the planet is, however, a major exporter of ivory. Reason: the amount of mammoth fossils, an extinct relative of the elephant, that is found there.

Did you know that The biggest shark that ever existed was the megalodon. He was three times bigger than the modern white shark. His teeth were up to 20 centimeters long.

Did you know that Charles Darwin never said that the man came from the monkey. He just stated that humans and monkeys could have a common ancestor, probably a primate.
