We know why you’re here; you’re looking for some incredible facts about space. Well, you’ve come to the right place. In this blog post, we’ll talk about some facts about space that will blow your mind.
With trillions of objects in several billion galaxies, the sheer vastness of space is utterly incomprehensible to the human mind. While we’ve been reading about the solar system for our entire lives, deep space is much more than that alone. It is a bizarre place with numerous “alien” planets and mysterious moons, and even things that we might not even know about yet. Space and everything in it is so out of this world, literally, that it eludes logical explanation.
So, now for the main event. We have listed some of the most incredible facts about space for you that will leave you utterly awestruck!
1. There Is Complete Silence In Space
Space is devoid of any atmosphere, which means that there is no medium for the sound waves to travel, and hence be heard. This means that there is complete silence in space. Radio waves, however, can travel through a vacuum, which is why astronauts make use of radios to communicate with each other when they’re out in space.
2. The Temperature of the Hottest Planet in Our Solar System Is 450oC
Water boils at 100-degree Celsius, which is the closest we ever get to such high temperatures under normal circumstances. Now, what if we told you that the hottest planet in our solar system has an average temperature of 450-degree Celsius? Now that is something!
The planet in question is Venus. Yes, Earth’s sister planet is the hottest planet that has been discovered to date, even though it is not the closest planet to our sun. Mercury is the closest to the sun but does not have any fixed temperature since it lacks an atmosphere. Thus there is massive fluctuation in its temperature.
Due to Venus’ thick atmosphere and its runaway greenhouse effect, the heat stays within the planet, which is why it is so consistently hot there.
3. We Can’t Count the Number of Stars in Space
Despite years and years of research, scientists still don’t know the number of stars out there in the vastness of space. We can approximate that the Milky Way is home to about 200 to around 400 billion stars.
But that’s just one galaxy. Scientists estimate that there might be billions and even trillions of galaxies in the universe. Multiply the estimated number of galaxies by the estimated number of stars in our Milky Way, and you get a number that’s truly uncountable!
4. Mars May Have Had Life At Some Point
How many times have you seen a movie featuring aliens? The concept of life on a planet other than Earth has been under investigation and research for many years, and according to some evidence, Mars might just be that planet.
In 1986, NASA retrieved a rock from Mars, which they thought could be fossils of microscopic living organisms. This formed the basis of the theory that there might have been life (at least microbial life) on Mars at some point in its history.
5. Neutron Stars Can Spin At An Incredible Rate of 600 times/Second
Neutron stars are the smallest and the most abundant stars in the universe (that we know of). These stars have a radius of 20 km or 12.5 miles, but that’s not what makes these stars special. Even though neutron stars are that tiny, they have a mass that’s 1.5 times the mass of our sun!
Just to put that into perspective, if you were able to scoop up even a teaspoon of a neutron star (you’d be killed by its magnetic field long before you got anywhere near the star), that one teaspoon would weigh about one billion tons!
So, what creates these monsters of space? They’re formed after a star goes supernova! When the star collapses in on itself, the neutrons are squeezed so tightly that there isn’t any room for them to move. What you’re left with is a small, dense star that’s made entirely of neutrons, hence the name.
What’s more, they can spin at an incredibly fast rate of 600 to 712 times per second!
6. There Might Be A Planet That Is Made Out of Diamonds
According to research conducted by the scientists of Yale University, there is a planet called 55 Cancri E, which is 8 times the mass and 2 times the radius of Earth. The gravity of this planet is so strong that scientists think that it might have a surface made up entirely of diamonds and graphite.
Although this planet is 40 light-years away from the Earth, it is still visible in the constellation of Cancer. How unbelievable is that?
7. The Footprints Of The Apollo Astronauts Will Stay on the Moon for Years to Come
There is no atmosphere around the moon, which means there is no wind that can erode away the surface or any water that can wash the Apollo astronaut’s footprints away. It implies that the footprints that the Apollo astronauts left behind on the moon, along with the discarded material and rover-prints, are likely to stay on the moon’s surface for generations to come.
8. The Sun Accounts for 98% of the Total Mass of Solar System
There is a reason why we call the sun the king of the solar system. It’s a massive ball of burning gases that accounts for 98% of the total mass of the entire solar system. The sun is a G-type main-sequence star. Our sun fuses around 600 million tons of the lightest element in the universe – hydrogen – every second and converts approximately 4 million tons of matter into energy in the form of heat.
When the sun finally dies – don’t worry; it’s not happening for another 5 billion years at the least – it will turn into a red giant that would envelop the Earth and all its contents.
9. A Single Day On Venus Is Longer Than A Year On Earth
Back to Venus we go! The rotation of Venus is fairly slow. How slow? It’s so slow that it takes Venus 243 Earth days to complete a full rotation and 226 days to complete a single revolution around the sun.
The sun “rises” once every 117 Earth days on Venus, which means the sun only rises twice in the entire year on Venus (which technically is the same day on Venus – trippy, right?). Moreover, the direction of rotation of Venus is clockwise, so it’s in retrograde. Therefore, the sun rises in the west and sets on the east.
10. The Size of Jupiter’s Red Spot Is Shrinking
Jupiter is famous for its massive red spot, which once was big enough to fit in three Earths. However, over the past few decades, the spot has been shrinking in size and now is big enough to fit only a single Earth.
What’s more surprising is the fact that although it is decreasing in width, it is increasing in height! Scientists are still dumbfounded as to why this is happening.
Space is a massively vast, and it’s unlikely that we’ll ever uncover all of its secrets. Even after spending decades studying the space, we haven’t even scratched the surface when it comes to facts about space. Space is mysterious, and that’s why we are so eager to learn all we can about it!
