15 Interesting Facts About Space

Despite advancing explorations beyond Earth, space is still largely a mystery to us. Whether he Balls of burning gas; holes that trap light and everything else; stars made out of diamonds; these are but a few of the many things that make our space a scary but wondrous place.

Read to find out some of the strangest facts about planets, galaxies, stars and other incredible objects around the solar system.


1. Hottest Planet


The hottest planet in our solar system is not Mercury as most would assume, but Venus. Due to runaway global warming, Venus' temperature is an incredible 863 degrees Fahrenheit (462 degrees celsius).

Not only is Venus' atmosphere blazing hot, but it also has an atmospheric pressure 92
times greater than the Earth's- that would crush you flat as a soda can if you walked
on its surface!


2. How Far Is Away Our Milky Way?

The width of our Milky Way galaxy according to NASA is about 1,000,000,000,000,000,000
kilometers, or 621371192237333888 miles- or in astronomical terms: 100,000 light years. Because most stars are so far away, when you look up into the night sky you are not seeing them as they currently are, but as they were thousands of years ago- that's how long their light takes to reach us.


Thee winds on neptune reach the speeds of 1600 miles per hour that's three times faster than a commercial airplane.

 


3. Bodyguard in Space

Many scientists think that without Jupiter life on earth would be impossible. That's because the giant of our solar system exerts such a strong gravity that it pulls in many comets and asteroids that might have impacted on Earth. Jupiter is like our personal bodyguard.


4. So Many Stars ⭐

Scientists estimate that there are hundreds of billions more galaxies in the universe, none of which you can see without a telescope. Moreover, each one of these galaxies has billions of stars, which brings the estimated grand total number of stars in the universe to 10 billion trillion. That's more stars than the number of grains of sand on the Earth.

All the stars, galaxies, and black holes in the universe only compose about 5% of its mass. As crazy as it sounds, the other 95% is unaccounted for. Scientists decided to label this mystery material Dark Matter. To this day, they are still not sure where or what it is.




5. Shortest Day in the Solar System

Jupiter is the planet with the shortest day in the solar system just 9 hours and 55 minutes because of its fast rotation. Jupiter isn't a perfect sphere the planet is a bit flattened but even though a day on Jupiter is more than twice shorter than on earth the year on this planet lasts way longer almost 12 earth years


6. Neutron Stars

Neutron stars aren't exactly stars they're city-sized objects with a huge mass usually about 1.4 times that of the Sun a neutron star is a collapsed core of a large star that ended its life in a brilliant burst of light turning into a supernova.

 Neutron stars are incredibly dense and keep getting even denser with time that's why a piece of neutron star material the size of a sugar cube would weigh a billion tons almost as much as Mount Everest the stars gravity is nothing but incredible - it's two billion times stronger than the gravity on earth.


Red Giant Betelgeuse, 1000 times larger than our sun, is a cosmic neighbor and expected to go supernova in the next 1,000 years.


7. Hubble Space Telescope

Hubble Space Telescope weighs almost as much as two male African elephants and is as long as a big school bus and made almost 1.5 million observations since it was launched in 1990 astronomers have used this data to write about 15,000 scientific papers everything on earth and everything people can see in space with the help of telescopes is normal. This Telescope gathers more than 10 terabytes of new data every year that's 2 million 5 minute long songs 3.1 million high-resolution pictures or 5 thousand hours worth of movies the telescope's total archive is over 150 terabytes of information



8. Closest Galaxy 

The Andromeda galaxy is the closest neighbor of our Milky Way it's just 2.5 million light years away if you squint really hard you can see it on a clear night with the unaided eye you can even wave at it but a more worrying fact is that in some 4 billion years our galaxy is likely to collide with the Andromeda galaxy experts believe earth will survive but the sky will look totally different from now.



9. Red Giants 

Red Giants are really old stars that form when stars 10 times the mass of our sun runs out of hydrogen in its core. As it collapses the hydrogen in the outer shells begin the process of fusion, and the entire star begins fusing hydrogen all at once. They will burn through all their fuel in just a few million years- unlike the billions it takes our sun- and shine 100,000 times brighter than our sun.


10. We are Martians?

Panspermia is the theory that life is transmitted like a virus from planet to planet by asteroid and comet impacts. A meteorite discovered in Antarctica was found to originate from Mars, and after careful examination some scientists believe it shows fossilized evidence of microscopic organisms- giving serious credibility to the Panspermia theory. We might all actually be martians.



11. Black Hole or White Hole


In general relativity predict that black holes were possible, but it also predicted that white holes could also be possible. The polar opposite of a black hole, a white hole is a region of space-time where matter cannot enter. A growing theory suggests that white holes are the opposite ends of black holes, and that our own Big Bang was a supermassive white hole that existed for fractions of a second.



12. Space Junk 


Space junk is any human-made object orbiting Earth that no longer serves a useful purpose. Scientists estimate there are about 500,000 pieces of space junk today which will surely increase in future.

Including fragments from rockets and satellites, and everyday items like spanner dropped during construction of the International Space Station.


If the Sun was the size of a front door our planet would be the size of a nickel, In other words the Sun could fit more than 1 million earths


13. Sun makes up 99.8 percent of the solar system’s mass


The sun is so large that it would fit one million planet Earth inside of it. It makes up 99.8 percent of our entire solar system’s mass and holds everything within it together thanks to its gravity, from the smallest particles to the biggest planets. Despite its huge mass, the star is just a ball of hot gas and would be impossible to stand on.



14. A full NASA space suit costs.

An astronaut suit does cost a fortune. It’s approximately 12 million US dollars. However, you can say that it’s expensive, but really, the suit is worth every penny. It weighs 21 kilograms and comes built with several costly materials and diverse layers. It also takes years to make a single suit. While the entire suit costs a cool $12m, 70% of that cost is for the backpack and control module.


Space-Craft have visited all the known planets in our solar system.



15. Space Is Completely Silent

There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.


Space for many is a weird & wonderful thing. The great unknown is something mankind has always observed and tried to learn from - by understanding our galaxy we may be able to understand our place in it, and how this world came to be.
