4. The sun makes up 99.86% of the mass of the solar system. Its size is such that 1.3 million Earths might be contained within.

5. There might be as many as three sextillion stars in the universe. That is 3 followed by 23 zeros, or 300,000,000,000,000,000,000,000. That is more than all of the grains of sand on Earth.

6. Ordinary, observable matter (like stars and planets) makes up a measly 5% of the universe. The other 95% universe is made up of invisible dark energy (68%) and dark matter (27%). That means there is 7. 95% of the universe that we don't know about yet.

Astounding information about the cosmos is presented here:

The size of the observable universe is 93 billion light-years, demonstrating the enormousness of the region beyond our solar system.

The number of stars in the universe—approximately 70 sextillion stars—is greater than the total number of grains of sand on all of Earth's beaches.


Not only are black holes filled with matter, but their gravitational pull is so powerful that not even light can evade them.


The cosmos is spreading in a straight line from its starting point; there is no discernible centre or boundary to it.


Despite appearances, the vast majority of the cosmos is empty space; in fact, atoms consist of 99.9999999999996% empty space.


General relativity states that gravity has the potential to distort time, which opens the door to the theoretical possibility of time travel.


The idea of the multiverse raises the intriguing prospect that our world is just one of many, each with its own set of physical laws.


The cosmic microwave background is the universe's oldest light, dating back to a period not long after the Big Bang (about 380,000 years ago) and revealing details about the early cosmos.


These selections show the vastness and enigma of our universe, which beckons for boundless investigation and revelation.
