20 FACTS ABOUT SPACE YOU DIDN'T KNOW

If you were impressed by the first image of Sagittarius A, the black hole in our galaxy, get ready, because today you'll not only see, but also hear menacing supermassive black holes. 20 Facts About Space You Didn't Know 1. The Great Attractor Classified as a gravitational anomaly, the Great Attractor could mean the end of what we know as This mysterious force is located in the Laniakea supercluster and, like a hungry monster, it's gradually attracting enormous amounts of matter. This includes the Milky Way and neighboring galaxies within a radius of over 300 million light-years away. Something like a galaxy-devouring Pac-Man. How close are we to falling into this pit? No one knows. 2. 55 Cancery E and Space Mining Thanks to the exposure of carbon to high pressure over a prolonged period, almost one-third of the planet 55 Cancery E is diamond-shaped carbon. Plus, this planet has an Earth-like atmosphere containing water and even oxygen. Believe it or not, we aren't so far away from obtaining its precious resources. Thanks to the Space Law 11490, promoted by former President Obama, space mining is encouraged. So, in the future, it'll be possible to have a diamond ring from this planet. What do you think? 3. Impressive Sounds From Space Space movies weren't that far off the mark. At the beginning of 2021, NASA published new audios of stars and galaxies after a Listen to the sound of twin galaxies AM 2026-424. A terrifying black hole. Here's Jupiter and the fascinating sound of Tabby's star. Truly shocking! 4. It's possible to touch the sun In December 2021, NASA's Parker Solar Probe touched the sun for the first time in history. This probe, prepared to withstand over 2,500 degrees Fahrenheit, flew through the sun's corona without melting. It even took samples of the particles and magnetic fields there. A big step towards discovering new information about this star and its influence on the solar system. 5. Two black holes threaten Earth Two major devouring threats in space were recently discovered. Although these supermassive black holes are located in the galaxy NGC 7727, about 89 million light-years from our planet, they're the closest to Earth detected so far. They've also broken the record for the closest separation between two supermassive black holes since they're only 1,600 light-years apart. At some point, they'll eventually merge into one monstrous black hole. 6. A major imminent solar storm Better get ready, because a major solar storm has been predicted for 2023 or 2024. How can you be sure of that? History tells us. The Carrington event of 1859 was the largest solar storm ever recorded that shorted out telegraph systems and caused numerous fires. In this day and age, it'd mean damage to satellites, the power grid, radio, and GPS signals. This almost happened in 2012, but that time the Earth wasn't in the path of the storm. Since the sun has an average activity cycle of 11 years, you know what's coming. 7. A spacesuit worth millions of dollars Ready for your next trip to space? For this, you'll need to get a good spacesuit. How much would this cost? In 1974, each complete spacesuit cost NASA $12 million. Today, they could cost $150 million. If you think you can do with that one, let me tell you that you'd only last 15 seconds in space before you lose consciousness and air bubbles start forming in your blood. Kind of like what happened to Arnold Schwarzenegger in Total Recall. 8. Space debris – a huge problem We seem to have left carbon footprint in space since 1957, when the space age began. The European Space Agency estimates there are about 900,000 useless objects of all size orbiting the Earth. Rockets, spacecraft, or satellite carcasses seriously jeopardize future missions and even ground communications. 9. Thieving galaxies It seems there's also a fierce struggle for survival in space. So much so that the largest galaxies will not pass up the opportunity to take molecular gas from other galaxies. According to the International Center for Radio Astronomy Research, the largest galaxies steal this molecular gas from neighboring smaller satellite galaxies to grow and form new stars. 10. The Milky Way – a zombie galaxy Did our galaxy die billions of years ago? According to scientists at Tohoku University in Japan, who studied stars, there was a long period when the Milky Way ceased star formation, meaning it died. But supernova explosions injected iron into the gas of the Milky Way and, as the gas cooled, the creation of the second generation of stars, including our sun, began. So don't worry, the Milky Way will be around for a while. At least until it collides with the Andromeda Galaxy in about, oh, 4 billion years. 11. The blue sunset on Mars Did you think everything was red on Mars? You might think so because the atmosphere is mostly CO2 and filled with iron-rich dust, which scatters red light. However, NASA's Curiosity Mars rover captured these images of the sunset. The Martian atmosphere has fine particles that allow blue light to penetrate the atmosphere more efficiently and, during sunset, when sunlight travels a longer path through the atmosphere than at noon, so much red light is filtered out that blue light passes through, making the sunset blue. 12. Urine, a valuable element in space As unpleasant as it may seem, in order to save space and resources, astronauts make the most of urine. It's not exactly what you're thinking. The oxygen and hydrogen in urine are separated through an electrolysis process to make more oxygen available on board. Astronaut's urine is also treated to turn it into drinking water. 13. Star Wars in real life Remember the planet Tatooine from Star Wars where Luke Skywalker came from and had two suns? Well, the planet Gliese 667 cc, 22 light-years from Earth, has three suns. The most amazing thing is that its conditions would support human life. Do you see yourself enjoying that sunset? Now we're off to the dark force with Mimas, the real Death Star. Mimas is a moon that revolves around Saturn. A giant crater gives it a similar appearance to the one we know as the Death Star from Star Wars. Impressive! 14. A ticket to the moon by 2024 NASA has announced its next trip to the moon for 2024. How much will this cost? Between 20 and $30 billion. Currently, the up-and-coming commercial spaceflight market offers tickets ranging from $50,000 with World View to $28 million with Jeff Bezos' Blue Origin. If traveling to Mars is your thing, Elon Musk says the roundtrip will cost $100,000. What do you think? 15. The Earth isn't round Here, I won't try to convince you that the Earth is flat. But believe it or not, this theory is promoted by many experts and celebrities such as rapper B.o.B., Shaquille O'Neal, YouTuber Logan Paul, and even the house music duo Daft Punk. The Flat Earth Society even has a documentary on Netflix. Unbelievable! The truth is that thanks to advances, there are more accurate measurements of the Earth. And yes, it is an oblate spheroid, meaning a geoid slightly flattened at the poles as if someone had sat on it. 16. Einstein's white holes You already know about the hogging force of black holes. But is there something that's their exact opposite? For now, their existence has only been concluded thanks to the equations posed by Einstein. White holes would be a visible region and, according to the California Institute of Technology, instead of swallowing everything, they'd be constantly expelling matter from their confines. Also, white holes could be a black hole, but in the future. Plus, the bottom of a black hole could be connected to a white hole by a wormhole. Quite complex. 17. Water in a galaxy far, far away One of the most distant and massive. The galaxy SPT 031158 has contributed to shed more light on the early universe. A study in 2021 found water and carbon monoxide in large quantities, inferring that they were already present and combined to give rise to stars and galaxies very early in the history of the universe. Something that was not certain and shows distances so far away where water exists. 18. The biggest thing in space Could it be the sun, a massive black hole, or a galaxy? Right answer. A galaxy named Alcyoneus. It's a supergiant elliptical galaxy 3 billion light years from Earth. The size of this gigantic galaxy is more than 160 times the size of the Milky Way. This makes it the largest galaxy ever discovered in space as of 2022. 19. Would the Earth survive the sun's death? The sun's death is predicted in about 5 billion years and, as it becomes a red giant, it'll engulf Mercury, Venus, and probably Earth. However, theories have emerged that consider that the sun's death may not reach the Earth. If humankind somehow protected itself during the red giant phase, it could rise again in the sun's white dwarf phase. Sound a lot like science fiction? Well, what makes more sense is that, once in the white dwarf stage, some kind of life could once again flourish on Earth. 20. 40 planets you could live on In March 2022, NASA made the great discovery of over 5,000 exoplanets, that is, outside our solar system. Out of those, at least 40 planets could support human life, like Ross 128b, a rocky exoplanet apparently with water on its surface 11 light years away. The only drawback is that a whole year here lasts only 10 days. Another one, already very famous in the alien universe, is Kepler-22b, which could have an Earth-like atmosphere and a pleasant temperature of 80.6 degrees Fahrenheit.
