If you feel consumed in the drama of the world, let these powerful facts about the universe ground you in the truth that life is so much more—maybe more than we could ever imagine.
“The cosmos is within us, we’re made of star stuff. We are a way for the cosmos to know itself.” – Carl Sagan
Life is more exciting, and possibilities are vast, when we think on a larger scale. It’s easy to get caught up in the goings-on of the world we live in, overwhelmed by all there is to know, to do, and to be; no matter how tired or withdrawn or stressed out we feel, the world just keeps on spinning. This might make us feel more separate from where we’d like to be and how we’d like to feel, but today is a reminder that you’re part of everything, and everything is part of you.
Neil deGrasse Tyson, astrophysicist and science communicator, once said something that really struck me: “Many people feel small because they’re small and the universe is big, but I feel big, because my atoms came from those stars. There’s a level of connectivity. That’s really what you want in life: You want to feel connected; you want to feel relevant; you want to feel like you’re a participant in the goings-on of activities and events around you. That’s precisely what we are, just by being alive.”Separation is not true; just by being alive, you're part of everything and everything is part of… Click To Tweet
Take a step back. In the picture below, taken by the Hubble telescope, there are thousands and thousands of galaxies, each containing millions of stars, each with their own planets. This picture is just a tiny fragment of what we can see in the night sky, a partial vision of the whole.
There are more stars in space than there are grains of sand on every beach on Earth. Let’s not lose our appreciation for the miracle of life, and let’s embrace again the childlike wonder that sees beyond the obvious frustrations of humanity; there’s more at play than pain and pleasure.
Here are some facts about the universe that have me shaking my head in wonder…
23 Fascinating Facts about the Universe
1. When we look up into the starry sky, we are only seeing something like 0.000003% percent of what’s out there. In fact…
2. 90 percent of the Milky Way Galaxy is invisible.
3. Within the distance between Earth and the moon, you can fit every planet in our Solar System.
4. Our Solar System takes approximately 225 to 250 million years to rotate around the Milky Way. The last time Earth was in its current position, dinosaurs were just beginning to roam the Earth.
5. 30 light years away in the constellation Leo, there is a planet covered in burning ice. “… Extreme pressure forces the water to stay in solid form, even though the temperature exceeds 570° F (300° C). The outer layer of the solid water is superheated and comes off as vapor.”
6. If you could compress the Earth down to the size of a marble, it would collapse in on itself and become a black hole.“You are the Universe, expressing itself as a human for a little while.” – Eckhart Tolle Click To Tweet
7. A black hole is a great amount of matter packed into a very small area, resulting in a gravitational field so strong that nothing, not even light, can escape. Think of a star ten times more massive than the Sun squeezed into a sphere approximately the diameter of New York City. And we can’t see it.
8. Some say that *if* you could look out from inside a black hole, you would be able to see the entire universe in one small patch of the sky – including the back of your own head.
10. A white dwarf star is a small star, about the size of Earth, and one of the last stages of a star’s life. Stars as small as our planet are that tiny because they are nearing their own destruction, which will lead to the birth of more stars.
11. In billions of years, when our sun is at the end of its life, it will become a red giant star (bigger and cooler), then it will turn into a glowing ring of gas (called a planetary nebula), and finally a white dwarf star.
12. W26 is one of the biggest known stars in the universe; it’s about 1,500 times wider than our Sun. The red supergiant star is nearing the end of its life.“Everything in the universe has a rhythm, everything dances.” – Maya Angelou Click To Tweet
13. According to the best estimates of astronomers, 275 million new stars are born every single day.
14. There could be anywhere up to 400 billion stars in the Milky Way galaxy and up to 50 billion planets. If even 1 percent of those are in their systems’ Goldilocks zone, then there are 500 million planets in our galaxy alone capable of supporting life.
15. The Milky Way is part of a small group of nearby galaxies called the Local Group. There are about three dozen galaxies in the Local Group.
16. Our galaxy is at least 100,000 light-years in diameter, making it the second-biggest in our Local Group of galaxies.
17. At approximately 2.5 million light years away, the Andromeda Galaxy is our closest massive galactic neighbor. If it were visible to the naked eye, it would be about six times larger than the moon in the night sky.
18. We are a far-flung part of the Virgo Cluster, the nearest big cluster at about 60 million light years away and boasting a collection of about 2,000 galaxies, many of which are as large or larger than the Milky Way. Its total mass may be around a quadrillion times the mass of our Sun.“Look deep into nature, and then you will understand everything better.” – Albert Einstein Click To Tweet
19. Our galaxy is currently eating several other, smaller galaxies. They’ve been ripped into long curving arcs of stars that orbit the center of the Milky Way
20. If you shrunk the sun down to the size of a white blood cell and shrunk the Milky Way galaxy down using the same scale, the Milky Way would be the size of the United States.
21. About 1 percent of the static on your television is caused by Cosmic Microwave Background (CMB) radiation left over from the Big Bang about 13.7 billion years ago.
22. Every atom in your body was formed in stars or in the explosive aftermath of the Big Bang, billions of years ago, trillions of miles away. You live because stars died.
23. It is concluded that 93 percent of your body mass is, in fact, stardust.
