The universe is far stranger than what our eyes alone can see.
Behind every streak of light or swirling galaxy lies a story shaped by forces beyond imagination.
From the quiet drift of rocks in space to colossal galactic encounters, the cosmos constantly challenges our idea of what’s ordinary.
In this article, we uncover astonishing truths about galaxies, meteors, and the asteroid belt, which reveal just how mysterious and surprising our universe is.
5 Random Fun Facts About the Universe
1. Galaxies can collide and merge into larger galaxies.
What do people usually think?
When the topic of a galactic collision comes up, they tend to think of it like two planets that are solid hitting one another.
They visualize two spheres, which resemble Earth, hitting like a car crash and making a massive impact.
Here is the astonishing reality:
Instead of a “car crash” type of collision, galaxies collide in a way that is not solid.
Instead, the gas clouds in galaxies are compressed, which leads to the birth of new stars.
Sometimes, if two galaxies can’t go through each other, they combine into one giant galaxy.
The new galaxy looks different from the two that joined.
Additionally, according to research presented by the Associated Press, there’s a 50% chance that the Milky Way itself is on course to collide with the Andromeda Galaxy in about 10 billion years.
2. Meteors are tiny, but they burn bright due to friction in Earth’s atmosphere.
What do people usually think?
Many people believe that shooting stars are those actual stars that have fallen from the sky—an occurrence that we wish upon.
However, what if these shining lights are not stars?
Here is the astonishing reality:
Meteors are not stars at all. These are tiny fragments of rocks that drift through space, hit our atmosphere, and which we once thought were shooting stars.
When these rocks enter the Earth’s atmosphere, friction with the air generates intense heat, causing them to glow brightly.
However, when these fragments of rock are in space, they are called meteoroids, but when they land on Earth, these pieces are known as meteorites.
3. Some Martian meteorites have landed on Earth.
What do people usually think?
People usually think that all meteorites that have landed on Earth are just random fragments of rocks in space.
What if I told you that some meteorites came from Mars?
Here is the astonishing reality:
The small fragments of rocks, also known as Meteorites, are not just random rocks.
According to NASA Science, most fragments of rocks found on Earth were from splintered asteroids, while some of these tiny rocks are from Mars or the Moon.
For instance, the Martian meteorite was formed when fragments from the planet Mars were blasted off its surface due to its powerful impact.
Since Mars’s composition includes weaker gravity and a thinner atmosphere, it is easier for the rocks to shatter into space.
4. No meteorites from Mercury have ever been confirmed on Earth.
What do people usually think?
We often conclude that if some meteorites come from Mars and the Moon, then Mercury, too.
But that kind of logic doesn’t work in this case.
Here is the astonishing reality:
Scientists confirmed that no meteorites have been found to have originated on Mercury.
Its location and strong gravity make it harder for rocks to break and reach the Earth’s atmosphere.
Candidates like Northwest Africa 15915 and Ksar Ghilane 022, the two well-known meteorites, are still examined to clarify claims about their connection to Mercury.
5. The asteroid belt isn’t crowded — objects are spaced very far apart
What do people usually think?
The asteroid belt is a famous demarcation separating the rocky planets from the gas giants.
Movies portray it as a region between Mars’ and Jupiter’s orbits, filled with millions of colliding debris.
A scary and chaotic place. This is how we envisioned the asteroid belt.
But what if I told you that we are wrong?
Here is the astonishing reality:
The asteroid belt lies between 2.1 and 3.3 AU from the sun.
It is home to millions of irregularly shaped space rocks, called asteroids.
But despite the sheer number of asteroids within the region, the asteroid belt is mostly space.
It is because asteroids are relatively small.
One asteroid can be as small as 10 meters across. One of the largest known asteroids is Vesta, which measures 530 km in diameter.
What’s even crazier is the fact that if you fly your spaceship through the asteroid belt, the odds of you encountering an asteroid are only one in one billion!
Wrap-Up
From galaxies colliding in silence to meteors burning brightly in our skies, each phenomenon shows us that space is both violent and beautiful in ways we can barely comprehend.
Even the asteroid belt, often imagined as chaos, is instead a vast expanse of emptiness punctuated by scattered fragments.
These discoveries remind us that the truth of the cosmos is far more fascinating than fiction.
