Out-Of-This-World Facts About Space
It's a universal experience to have stared up at the heavens, and wondered what is out there. Few of us can spend much time under a canopy of stars without marveling at our own seemingly inconsequential size in comparison to such endless space.
Perhaps that's why so much of human thought has been driven by the desire to understand more about our place among all those bright lights. From the time of philosophers like Eratosthenes and Aristotle, who used the mysteries of the solar system to drive their pursuit of knowledge, to more recent heroes like Stephen Hawking, we have been captivated as a species by the cosmos.
So if you, like so many before you, often find yourself wondering at the vastness of eternity... you've come across the right article. We've written this for you, to answer as many questions as we can with this ultimate list of facts about outer space
Happy reading.
Space Facts
1. Minor temperature differences.
Upsilon Andromeda B, an extrasolar planet approximately 44 light-years away from the Sun, also only faces one side to its star.
It has what you might think of as the planetary-equivalent of a split personality: One side of the planet is hot as lava, while the other one is consistently below freezing.
If you've ever taken a shower at a friend's house, and found yourself utterly bamboozled by their Rubiks Cube of a hot/cold water knob, you will known what life is like on Upsilon Andromeda B. Or rather, what life isn't like on Upsilon Andromeda B.
You know...cause you'd be dead.
2. Kaboom!
If you placed a pinhead-sized piece of the Sun's core on the Earth, you would die from standing within 145 km (90 miles) from it. Why? Basically, it contains a wack ton of energy, and it'll blow up like a freaking nuclear bomb.
3. Is there anybody out here?
Space is not a complete vacuum. There are about 3 atoms per cubic meter of space. Massive understatement of the century: that's not a lot.
To put it in perspective, at sea level, there are approximately 2.5 x 10^25 air molecules in a cubic meter of air. That's 250,000,000,000,000,000,000,000,000 atoms.
