10+ interesting facts about space

I always wanted to be an astronomer when I was a kid. It is like my dream that never came true. Mostly because when I was in high school I found out that I was terrible at math, and that crushed my dreams. Although, I still read a few books about astronomy and watched some documentaries about space. Carl Sagan, for instance, is a sacred word inside my house. And I know some of you had the same dream, or when you were kids you dreamed of being an astronaut. This is why I decided to make a list of the most intriguing facts of space. I hope you like them!





The first person that looked into space with a telescope was named Galileo Galilei. This happened 400 years ago. Ever since science has made major breakthroughs in terms of science and astronomy

Smell the roses


The smell of flowers depends on several factors such as the environment, the temperature, the humidity, and the age. This is why flowers, especially roses, have such a different smell in space than they do on planet Earth



As a matter of fact a long time ago the smell several roses were grown within the space shuttle called discovery it was sold a perfume by a Japanese company named Shisedo. The perfume was called Zen it was a huge success



Many people don't know this space is quite flexible, actually. It has been expanding at a rate able to measure the beginning of times. In 1895 a rocket Russian scientist named Constantine was the first person ever to talk about the idea space elevators, which was a sort of space transportation system



You have seen the Star Wars The Empire Strikes Back scene where Han Solo navigated through an asteroid belt but as a matter of fact, asteroids measure 400.000 miles. They are quite big and it is impossible with one asteroid.



Let's keep talking about wrong space scenes in movies. There is no sound in space. In the film 2001 a Space Odyssey it is also the scene of Bowman since he should have exhaled air in order to enter again to the ship after being locked out by Hal



The first animal sent to space was a dog named Laika, she was launched on the ship from soviet precedence named Sputnik 2 in 1957. She died within a week due to the fact that she died of running out of air



If you boil water on Earth it will create several little bubbles, but if you do it in space it will produce a giant bubble. This is because there is no existence of the convection and buoyancy there usually comes with gravity

Big Bang


The Big Bang theory states the idea of an "inflation theory", that means there was a fraction of a moment after the dawn of creation, right after it, when the entire universe literally made a sudden dramatic expansion.

It starts with a bang


The entire part of the "bang" lasted only seconds (about 30 of them or one million million million million millionths of a second), but it created the entire universe from something that could fit into a hand into something at least 10,000,000,000,000,000,000,000,000 times bigger.



The first American person to be sent into space was Alan Shepard, he was launched aboard the Mercury 3 space shuttle back on May 5, 1961. It did not enter orbit but traveled 116 miles before safely parachuting into the Atlantic Ocean



If you have a flame right here on Earth, it will rise. But if you do it in space, it will move outward from its source in several directions. Since space lacks gravity, the expanding hot air experiences equal resistance in all directions.

Guy Bluford


The first African American to be launched into Space was Guion "Guy" Bluford, Jr inside the space shuttle Challenger in 1983 alongside 3 other shuttle flights (one inside a Challenger and two on Discovery).



Like we said before, some cool things happen in Space. Again, for the lack of gravity and there isn't convection, the body heat won't rise off the skin. That means your organism will try to remain cool by itself but the sweat won't drip



Another strange result of not having gravity is that your body fluids rise higher in the body than they do on Earth, what does that mean? You have more fluids than the habitual inside the skull pressing on your eyes.



There are several types of colonies of bacteria that can grow so much faster in space. For example, Astro E-coli colonies grow almost twice as fast as E-coli on Earth, and salmonella grows much faster and even stronger while being on a space shuttle than on Earth



In space you do not have what it is called "buoyant force" What does that mean? Nothing can push bubbles up and out of carbonated drinks in space.

Sally Ride


Sally Ride was the first American woman to be sent into space back in 1983. She was launched into the space shuttle Challenger on June 18, 1983. Not only that, she was also the youngest American in space.

Collapsed Universe


There are some astronomers that believe and speculate that the singularity that became the Big Bang was the remains of an earlier collapsed universe, so that would mean our universe on a loop of expanding and collapsing universes.



The scientific community thinks that we can look into the period of time (those 10-43 seconds after the Big Bang) when the universe was so small that the only way to see it was under a microscope.

More numbers


Astronomers believe that at one ten-trillionth of a trillionth of a trillionth of a trillionth of a second after the Big Bang, the gravity simply emerged, and it was joined rather earlier than later by electromagnetism as well as strong and weak nuclear forces.

How many Bangs?


Part of the NASA staff stated that there might have been other "big bangs", even trillions and trillions of them spread across eternity. The only reason why we exist in it is pure coincidence and being the right particles at the exact time and moment. That's it.



There are several hypotheses within the astronomer's community for possible scenarios that created our entire universe: 1) we have a closed universe, and eventually, it will collapse into another singularity



The other two theories are that we have an open universe and it will keep expanding forever until everything is so far apart that the universe becomes inert and dead. And the other says that we have a flat universe

Bending Universe


A person will never, ever even try to travel to the edge of the universe. If someone traveled outward in a straight line indefinitely, he would come back to the part where he began.

Dark matter


There is a general agreement amongst scientist that nearly ¾ of the universe is missing in the form of dark energy and dark matter (it can't be been seen or measured) This is much needed in order to balance out the mathematics of the universeç

Supermassive black hole


What is a black hole? This question was asked for several years. A black hole is created when a large star explodes and the leftover remains of the core collapse into an object so small and dense that its gravity becomes too strong for even the fastest thing in the universe.

Dark matter


Dark matter, something that goes alongside with dark energy (it always does) is the "glue" that holds the universe together. But it can't be measured, although it is possible to detect it rather than the dark energy

Cosmic Rays


Cosmic rays are mostly particles with a huge amount of energy that flows throughout our solar system from deep in outer space, but it is impossible to figure out how they are originated or where did they come from

Solar System


If you make a diagram of the solar system on a scale, if the Earth is the size of a small pea, Jupiter would be over 1,000 feet away from Earth and Pluto would be a mile and a half distant, with the size of a bacteria



Pluto is far away and very much distant, but it is not located on the edge of our solar system. The edge is believed to be beyond past from the Oort cloud, which, and it takes 10,000 years to reach.



Our nearest location in space beside the solar system, is the Proxima Centauri (and it is also part of a cluster called Alpha Centauri), is 4.3 light years away (a hundred million times farther than a trip to the Earth's moon).

Milky way


It is impossible to figure out how many stars the Milky Way has, it is estimated that the range goes from 100 billion to 400 billion). Besides, it is not the only galaxy, there are 140 billion galaxies

How old is the Universe?


The same theorists that believe in the Big Bang estimated that the Universe is almost 13.7 billion years old, and it would take you 156 billion years to cross it entirely across. The diameter would be larger than its age because it has been expanding since then

Carl Sagan


The famous and popular astronomer called Carl Sagan stated many times than the approximated number of probable planets in the universe is at 10 billion trillions. This sounds like a lot of time that we don't have.



Several officials from NASA stated many times during press conferences that the astronauts they launched to space never had intimate relationships on the International Space Station or during any space shuttle missions.

Space observatory


It is believed that the first space observatory may have been Stonehenge. It was built around 2600 B.C., and the Britons made stones that marked critical positions of the sun and moon throughout the year.

Outer Space


The first person to use the term nowadays known as "outer space" was in Lady Emmeline Stuart-Wortley's 1842 epic poem The Maiden of Moscow. It served as a description of the region beyond Earth's sky.



The temperature of the cosmic background radiation from microwaves that permeates the entire universe is 2.7° K (-270.45° C). Also, the star that shines the most is R136a1 in the Large Magellanic Cloud.



The oldest known star is the red giant HE 1523-0901. At 13.2 billion years old, it is almost as old as the universe itself. The Light from the stars, called photons takes 8 minutes 22 seconds to reach Earth from the surface of the sun

Visible points in the sky


There are "only" 6,000 stars visible to the naked eye from Earth, and only 2,000 can be seen from any one spot. But, if you don't use an element, like binoculars, the number of stars that can be seen from a single location is about 50,000.



Do you like eating because it tastes good? Well…if you become an astronaut, the will be a problem for you. Since there is no gravity and that diminishes the sense of taste. Maybe that is why they eat such terrible meals up there.



NASA launched a space shuttle named Challenger in 1986, that due to mechanical problems it exploded and everyone died. Scientist believe that astronauts survived for about two minutes after the initial fireball

Fly me to the moon


Right after Neil Armstrong and Buzz Aldrin returned to Earth from the moon, they had to stay under quarantine for 21 days because it was plausible they might have brought back with them some space plague.



Do you feel like you are not that tall? Well, you should become an astronaut since they can grow up to 3% taller if they spend at least six months within the International Space Station.

Adjust yourself


When astronauts return to Earth after spending a few months in space, they have a difficult time adjusting to gravity and they will often forget that things fall if you drop them.



Did you get lost in space? They have their own GPS. They use 88 named constellations to find their ways around the night sky, such as Orion, the zodiac signs, and Ursa Major

Star Trek


There are more than 100 ashes of human beings that were launched into space, including Star Trek creator Gene Roddenberry, psychologist/writer Timothy Leary, and Clyde Tombaugh, the man who discovered Pluto.

Shooting Stars


The actual "shooting-stars" that are not the meteors, are called hypervelocity stars and are as rare as one in 100 million. They were discovered back in 2005, and these stars shoot out of a galaxy at nearly 530 miles per second

Yuri Gagarin


The first human that was launched into space was a Soviet astronaut named Yuri Gagarin and orbited Earth in the space shuttle named Vostok 1 in 1961. The next year after that, American astronaut John Glenn, Jr., became the first American to orbit Earth
