There is nothing else besides the universe. It encompasses the entirety of space and every bit of matter and energy in it. You are a part of it, and so is time.
The cosmos includes not only Earth and the Moon but also every other planet and each of its dozens of moons. The planets orbit the Sun, just like asteroids and comets. Most of the billions of stars in our galaxy have their worlds, or exoplanets, just like our Sun does.
All galaxies, including our Milky Way, are assumed to be home to supermassive black holes. There are billions of galaxies in the observable universe. The cosmos consists of everything, including the stars in all the galaxies and the other stuff that astronomers can’t even view. Just put, it’s all there is.
We call the total of all things in the cosmos the universe. In addition to trillions of stars, galaxies, black holes, and gigantic clouds of gas, it contains countless other intriguing objects.
Many of us have always found the cosmos to be a fascinating mystery. Every one of us has wondered about many secrets of the cosmos and been fascinated by its constituent parts. The term “universe” refers to the total of all known astronomical objects.
It consists of many extraordinary objects, including trillions of stars, galaxies, black holes, and vast clouds of gas. Because of this, we have compiled a list of some of the most fascinating and crazy astronomical facts that we think you’ll enjoy reading.
1. Nothing Can Be Heard In Space
This is understandable because there is no medium for sound to travel through and be picked up in outer space. Since radio waves can be sent and received even in areas, astronauts use radios to keep in touch.
2. The Exact Number of Stars in the Universe Is a Mystery
How many stars are out there? That number is entirely unknown. Scientists and astronomers believe the Milky Way is home to between 200 and 400 billion stars. That means the number of galaxies in the cosmos is in the billions.
3. The 240s B.C. Marked the Beginning of Chinese Records of Halley’s Comet
After 164 BC, every time a comet was spotted, it was recorded. In 2061, we will be able to catch a glimpse of the next Halley Comet.
4. For The Next Hundred Million Years, the Footprints on the Moon Will Remain
There is no wind or water on the moon to erode the surface or wipe away the imprints because there is no atmosphere. So the Apollo astronauts’ prints, combined with the space prints, and rover prints, will be there for millions of years.
5. The Price Tag for NASA’s Spacesuit Is $12 Million
The price tag for a NASA spacesuit is roughly $12,000,000. However, the backpack and control module accounts for 70% of the price.
6. Water Floats Around In Space
Around 10 billion light-years distant, astronomers discovered a gigantic water vapor cloud that contains 140 trillion times the mass of water in all the oceans on Earth. It’s the most significant water find ever made.
7. The United States of America Is Larger Than Pluto
Pluto’s orbit makes it far smaller than the United States. If you walk around the equator of Pluto, it would be the same distance as going from London to Denver.
8. The Moon Is Traveling Away From Earth
Every year the moon migrates away from Earth by 3.8 cm. Scientists do believe that, ultimately, the Moon will migrate out of the field of Earth’s Gravity. However, this won’t happen for the next billions of years to come.
9. The Red Patch on Jupiter Is Fading
The red spot on Jupiter has diminished over the past many decades. The iconic red spot is a gigantic whirling storm that used to be able to fit three piles of earth. Nonetheless, as of recently, just one planet can enter, so the reports go.
10. The First Ever Photographed Black Hole Is Three Million Times Larger Than Earth
In April 2019, scientists revealed the first-ever image of a black hole, which depicts a ring of dust and gas surrounding the object. According to reports, it’s a whopping 310,000,000,000,000 kilometers from Earth. The photo was taken by the Event Horizon Telescope, an interconnected array of eight telescopes, and was made possible by an algorithm developed by computer scientist Katie Bowman.
