Last time we discussed the 10 amazing facts out of the 100 amazing and interesting facts of the universe. Today I am back with the next 10 amazing facts of this series. you could find the old ones below…

I hope you must have read the past two articles about the 100 amazing and Interesting facts of the universe. Each article contained 10 of the facts. Today also, we will discuss only 10 facts.
As we all know, our Universe is a realm of the mysterious and amazing objects. Each object has its own domain of mysteries that always amazes us by its mysterious deeds.
Again, for your information, these facts have been taken from the book 100 AMAZING FACTS ABOUT UNIVERSE by Faizan Aziz. You could get this book from the link above.
Now, I am not going to make you bored anymore. Rather we should start with the next part of the 100 amazing and interesting facts of the universe.
Can you See the Past? Ghosts in the Sky
I asked you a question in part 2, that was, can you see the past? Yes, we obviously can see the past.
Have you ever watched the sun? obviously you had. Now, tell me how much time do sunlight takes to reach the Earth? It’s 8 minutes and 20 seconds. So, the sunlight we get had emitted from the sun 8 minutes and 20 seconds before.
I hope you must have got my point. Whenever we see the sun, we see 8 minutes and 20 seconds back in the past. This is because of the time taken by light to reach our eyes.
Likewise, whenever we see the moon, it is not in its actual position. We actually see the moon’s position around 1 second before.
It would not be wrong if we say, we only see the ghost of those stars rather than their physical structure.
So this is our fact number 20. Whenever we see any celestial object, we actually see back in the time.
The Twinkling Stars may Be Dead
When we were kids we must have recited the poem, “Twinkle-Twinkle Little Stars” once in our childhood. All those stars are billions of light-years away from us.
Do you know, what is this twinling? Well, there are a large number of stars exploding each second in the universe and also forming a new one. This explosion and the formation seems to us like the twinkling of the stars.
So, the light emitted from those stars takes billions of years to reach us. By the time some of those stars may be dead as their nuclear fuel might be finished.
Most Massive and Luminous Star
Do you know which is the most Massive and Most luminous star in the Universe?
Well, there is a star located in the Large Magellanic Cloud. This Star is 8.7 Million times brighter than our sun. This is a Wolf-Rayet star located at the center of R136.
Due to its location at the center of R136, this star has been named as R136a1. Its actual location is at the center of the concentration of stars of the large NGC 2070 open cluster in the Tarantula Nebula.
This Star lies at a distance of 49.97 kiloparsecs (163,000 light-years) in the leading corner of the neighboring galaxy. This galaxy has many large nebulae with highly active star formation.
The Tallest Mountain in the Solar System
How many of you know, which is the tallest mountain in the solar system? Well, many of us will answer this question by “Mauna Kea” and some of us will say it is “Mount Everest”. But, both are incorrect answers.
The correct answer to the question is “Olympus Mons” located on Mars. Olympus Mons is the tallest mountain on any of the planet in the Solar System.
It is 26 kilometers tall, almost 3 times the height of Mount Everest. This mountain is sprawling to an area of 600 Kilometers across.
Unusual Characteristics of Uranus
Most of the planets in the Solar System spin on an axis similar to the Sun’s; slight tilts in a planet’s axis causes seasons as different parts become slightly closer or further from the sun during their orbit.
If we talk about Uranus, it exceptional in many ways like it spins at a tilt of 98 degrees, it rotates in the opposite direction compared to other planets. Due to this inclined rotation, it seems Uranus is rotating like a roller rather than spinning like a top.
This results in very long seasons – each pole gets around 42 Earth years of continuous summer sunlight, followed by a wintry 42-year period of darkness.
Uranus’s northern hemisphere enjoyed its last summer solstice in 1944 and will see in the next winter solstice in 2028.
The Search for Extra-Terrestrial Intelligence (SETI)
Scientists have started a project to discover whether intelligent life exists elsewhere in the Universe. How may we contact those extraterrestrial species?
This search includes looking for life on other planets and moons. for instance, some of Jupiter’s moon (such as Io) are promising places to look for evidence of primitive life.
The search for extraterrestrial life includes scientific research on Earth.
Life Has Generated more than Once
If scientists can discover evidence, life has generated independently more than once. It would suggest life could occur in more than one place, for more than one time.
For this reason, scientists are searching for evidence that life could have happened more than once on earth, with intriguing prospects for the universe as a result.
Billions of Stars in Our Galaxy
As we all know, our Sun is essential to us. It is the center of our Solar System. Our source of light and energy. But, it is just one of many, many stars that make up our home galaxy, the Milky Way.
Current estimates suggest there are around 400 billion stars sharing our galaxy. So, our sun is not alone, maybe neither we are.
Scientists are searching for extraterrestrial life on other planets. Those planets, they have acclaimed goldilocks planets. This is a category of planets that are in the habitable zone of the stars.
Planet Earth seems to have exactly the right conditions for life to exist. Its distance from the sun means the temperature is right. Water can exist as a liquid, solid and gas.
There are the right combinations of chemical compounds available to build complex life forms. Other planets having similar features are known as Goldilocks Planets.
In Milky Way alone there are estimated to be 500 million potential Goldilocks Planets. So, if life can exist in planets other than earth, there is a huge number of potential planets on which it might thrive.
If these numbers are applied to all the galaxies in the universe there could be a staggering variety of planets capable of supporting life.
Of course, we have no evidence life exists elsewhere, but if it does there are plenty of places for it to set up home.
Number of Galaxies in the Universe
Different calculations provide different numbers for how many galaxies there are in the observable universe. That is the part of the universe we can see from Earth with our current technology.
There may be many more but they are simply too far away for our telescopes to detect. Using data from the Hubble Telescope astronomers have calculated there are likely to be around 170 billion galaxies in the observable universe.
Largest Known Diamond of the Galaxy
Astronomers have discovered the largest known Diamond in our Galaxy. It’s a massive lump of a crystallized diamond called BPM 37093.
BPM 37093 or V886 Centauri is a variable white dwarf star. It has a high mass of approximately 1.1 times that of our Sun. It is about 50 light-years away from Earth, located in the constellation Centaurus.
So, we have discussed 10 amazing points out of the 100 amazing and interesting facts of the universe. we have discussed, ghosts in the sky looking in the past.
We learned the tallest mountain in the solar system is Olympus Mons. We also had a tour of the Large Magellanic Cloud and watched the most luminous star.
You have gone through the planets in habitable zones of the stars and knew about the number of potential planets suitable for having a life form.
This is not the end. Our universe is full of such mysteries. Even we haven’t searched all of them yet. We will be continued with a few more such facts in upcoming posts.
