The Universe is all of space and time and its contents, i.e. moons, planets, stars, galaxies intergalactic space and all matter and energy.
Universe has continued to amaze mankind for thousands of years, from early caveman to modern human the sky has been a mystery to mankind. Billions of dollars have been spent each year on space and universe exploration.
Today, man is in search of other habitable zones and planning to settle on other planets like MARS. Space travel will be a reality in the coming years, people like Elon Musk, Richard Branson are working on new spectrums and technologies to make it possible in the near future.
There are continuous discoveries every day about what we know about Universe and space, below are some of the facts which will amaze you about this ever-expanding universe.
Earlier, we have read about the 10 amazing facts of the solar system. But now, I am going to let you know 100 amazing facts of the Universe.
I would not take all the 100 facts in one post, rather I would choose to write 10 different posts having 10 facts each.
These facts have been taken from the book 100 AMAZING FACTS ABOUT UNIVERSE by Faizan Aziz. You could get this book from the link above.
1. Exoplanet covered in burning ice
Gliese 436 b is a Neptune-sized exoplanet located about 33 light-years away in the constellation Leo. Astronomers believe that it embodies exotic states of water that causes its surface to be covered in burning ice.
The pressure on the planet forces the ice to stay solid, but the extreme surface temperature of 570 ° F (300 ° C) superheats the water, causing it to come off as steam.
2. Eau de Cosmos- Odor of the Cosmos
Though it is impossible to smell space directly or through a spacesuit, astronauts report that upon returning from a spacewalk, their gear smells distinctively like seared steak, hot metal, and arc welding fumes.
The source of this odor could be a byproduct from dying stars, the traces of which can be found throughout the universe.
3. Intergalactic Kegger
About 10,000 light-years away in the constellation Aquila, there is a cloud of alcohol with a diameter 1,000 times larger than our solar system. The amount of ethyl alcohol present in the cloud could serve up to 400 septillions (400, followed by 24 additional zeros) drinks.
4. Closest Neighbor
The Andromeda galaxy is our closest galactic neighbor, roughly 2.5 million light-years away. Though it is 140,000 light-years across, it isn’t bright enough to be seen in the night sky by our eyes. If it were brighter, it would appear six times larger than the full moon.
5. Earth Under Pressure
Black holes are formed when some very large stars collapse and condense all of their mass into a very small area, known as the Schwarzschild radius.
Earth’s Schwarzschild radius is just below nine mm (1/ 3 inch), and if it were to be compressed below that size, our planet would become a black hole. For a person to become a black hole, they would have to be compressed smaller than a proton.
6. Stellar Nursery
Though the birth and death of stars don’t happen instantaneously, the process happens fairly frequently.
By using observed star formation and supernova events within the Milky Way, astronomers have estimated that 275 million stars are born and die throughout the observable universe each day. This totals more than 100 billion over the course of a year.
7. Galactic Year
It takes 24 hours for Earth to rotate on its axis to make a day, and 365 days to orbit around the sun for a year. It takes around 230 million years for our solar system to complete a single orbit around the Milky Way.
The last time it was in its current position, the earliest dinosaurs had just appeared, and flowering plants wouldn’t evolve for another 100 million years.
8. Macerated Milky Way
Our solar system may smell like hot metal and seared steak, but what about the middle of the Milky Way? According to recent research from the Max Plank Institute, it smells like raspberries and tastes like rum.
They found that ethyl formate, a key chemical component for both raspberries and rum, can be readily found at the center of our galaxy.
9. Time Flies
If you have ever wished there were more hours in the day, just be patient. Every century, Earth’s rotation slows down by about 1.4 milliseconds. When the dinosaurs were around, a day lasted about 23 hours.
NASA reports that Earth’s rotation was exactly 24 hours in 1820, but is now off by 2.5 milliseconds.
10. Habitable Zones
There are anywhere between 200-400 billion stars in the Milky Way and an estimated 100 billion planets.
Around one in five stars are like our sun, and astronomers have estimated that about 22% of them have planets the size of Earth in their habitable zone, where water can exist as a liquid.
This means there could be 8.8 billion planets within the galaxy capable of supporting life.
So, this was the 10 facts of the 100 facts of the Universe. We would check the next 10 in the next post tomorrow. So, stay singed in and wait for the next post.
