What are some mind-blowing facts about the universe?

 The best facts there is:

1.. When you look into the night sky, you are looking back in time.

The stars we see in the night sky are very far away from us, so far the starlight we see has taken a long time to travel across space to reach our eyes.

2.. There’s a giant cloud of alcohol in Sagittarius B.

Sagittarius B is a vast molecular cloud of gas and dust floating near the center of the Milky Way, 26,000 light-years from Earth, 463,000,000,000 kilometers in diameter and, amazingly, it contains 10-billion-billion-billion liters of alcohol.

3.. Our solar system’s biggest mountain is on Mars

Olympus Mons on Mars is the tallest mountain on any of the planets of the Solar System. The mountain is a gigantic shield volcano (similar to volcanoes found in the Haiiwain Islands) standing at 26 kilometers tall and sprawling 600 kilometers across.

4.. Neutron stars are the fastest spinning objects known in the universe.

The fastest spinning known pulsar is the catchily-titled PSR J1748-2446ad, which has an equator spinning at 24% the speed of light, which translates to over 70,000 kilometers per second.

5.. Our Galaxy Is on a Collision Course with the Andromeda Galaxy

Even though these two conglomerations of stars are destined to smash together, you shouldn’t lose any sleep over the incident. The impending impact won’t happen for another 3 billion years.

6.. Stellar Nursery

By using observed star formation and supernova events within the Milky Way, astronomers have estimated that 275 million stars are born and die throughout the observable universe each day.

7.. Quasar Query

Quasars occur when gas swirls around a black hole very quickly, and friction causes it to heat up, emitting light. Astronomers have a discovered a group of 73 quasars that are over 6.5 times larger than the average quasar group. This structure is over four billion light-years wide, and actually cannot be explained by the Theory of General Relativity. Theoretically, it shouldn’t even exist.

8.. There are probably more than 170 billion galaxies in the observable universe.

Using data from the Hubble Telescope astronomers have calculated there are likely to be around 170 billion galaxies in the observable universe.

9.. We are all made of stardust

This may sound fanciful, but the reality is almost every element found on Earth was created in the burning core of a star, all the stuff that makes up life on Earth, therefore our bodies are made from stardust.

10.. Long Galactic Year

It takes 24 hours for Earth to rotate on its axis to make a day, and 365 days to orbit around the sun for a year. It takes around 230 million years for our solar system to complete a single orbit around the Milky Way.
