Let us start with a new set of amazing and extraordinary facts of the universe.
As I told earlier, we all are familiar with the truth and that is we all are surrounded by a lots of fascinating things. we even can’t imagine, How fascinated those things are!
We, the dwellers of the earth only realize them and be wondered from afar distance with those amazing and extraordinary facts of the universe.
So, I am going to start with the next extraordinary and amazing facts of the Universe without wasting any time.
The End of the Universe
It is said, “everything which is born, must die once.” With the passage of time, everything has a lifespan.
Planets, Stars, Galaxies will all eventually cease to exist. With the Cease of planets, stars and galaxies, the universe and time itself will come to an end someday.

With the expansion of the universe, the matter becomes more dispersed. The gases and material that make up stars will be scattered over larger distances.
In this process of expansion and scattering, a day will come when the density of the universe will become very Low. It will be so low that it can not even be able to produce any new star.
Stars Changing its Form
By this time all the large stars and smaller sun-like stars will be gone. All that which left will be their burnt-out remnants in the form of black holes and black dwarfs.
There will be the chance of being remained is only one type star and that is Red Dwarf. Red Dwarf is a small dim star that burns its fuel at a very slow rate. It allows it to exist for trillions of years.
Any intelligent life that is lucky enough to be on a planet that orbits a Red Dwarf will look up at a black night sky, void of any bright points of light.
Birth of a White Dwarf
These Red Dwarfs also do not have an infinite lifespan. It too will eventually burn themselves out and will become faintly glowing ember known as a White Dwarf. these tiny points of light will only be left in the entire Universe.
The Universe will exist with its white dwarfs for trillions of years. Just imagine what will be the impact of that small amount of light emitted by the white dwarf.
It will be just like a firefly in kilometers of the darkness of the darkest night. This light will eventually fade away as there will be only darkness.
Birth of a Black Dwarf
The earlier light-emitting white dwarfs will lose its all property of emitting light in the darkness and will convert into a black dwarf.
A Black Dwarf is an incredibly dense object made from the cold ashes of a long-dead star. This is the last stage of any star’s life cycle.
These too will be broken down and dispersed until eventually absolutely no matter will remain in the Universe, not even a single atom.
The Universe will be a cold, empty unchanging void as time itself will come to an end. This can seem like a very depressing future but the good news for us is that it won’t happen for a very, very long time.
The Universe will continue to form new stars and galaxies for trillions of years, if you consider that at the moment it is only 13.7 billion years old you begin to realize that the Universe is just in its infancy, a baby if you like. Its future in a sense has just begun.
Everything has its own origin. So do galaxies have.
In the view of most astronomers, galaxies formed just after a cosmic “big bang”. This “big bang” began the formation of the universe long ago around 10 billion to 20 billion years.
In the milliseconds after that explosion, clouds of gases started to coalesce, collapse, and compress under gravity to form the building blocks of galaxies.
Scientists have divided ideology on how galaxies first formed. Some believe that smaller clusters of about one million stars, known as globular clusters, formed first. Later gathered into galaxies.
Others believe that galaxies formed first and that only later did the stars within them begin to gather into smaller clusters.
So, it was just a glimpse of the origin of the galaxy. We will explore it more some other day in some other specific article.
Some galaxies occur alone or in pairs, but they are more often parts of larger associations known as groups, clusters, and superclusters.
Galaxies in such groups often interact and even merge together in a dynamic cosmic dance of interacting gravity.
Mergers cause gases to flow towards the galactic center, which can trigger phenomena like rapid star formation.
Our own Milky Way may someday merge with the Andromeda galaxy—just two million light-years away and visible to the naked eye from Earth’s Northern Hemisphere.
These intergalactic processes may be part of natural evolution by which irregular galaxies transform into one of the other shapes, and by which spiral galaxies eventually become elliptical galaxies—as scientists believe they must.
TYPES OF GALAXIES
Galaxies are classified into three main types: spiral galaxies, elliptical galaxies, and irregular galaxies.
Spiral galaxies, such as the Milky Way, consist of a flat disk with a bulging center and surrounding spiral arms. The galaxy’s disk includes stars, planets, dust, and gas—all of which rotate around the galactic center in a regular manner.
This spinning motion, at speeds of hundreds of kilometers per second, may cause matter in the disk to take on a distinctive spiral shape like a cosmic pinwheel.
Some spiral galaxies obtain even more interesting shapes that earn them descriptive names, such as sombrero galaxies. Older stars reside in the bulge at the center of the galactic disk.
Many new stars also form in spiral systems, and their disks are surrounded by a halo, which scientists believe is rich with mysterious dark matter.
Elliptical galaxies are shaped as their name suggests. They are generally round but stretch longer along one axis than along the other. They may be nearly circular or so elongated that they take on a cigar like an appearance.
Elliptical galaxies contain many older stars, up to one trillion, but little dust and other interstellar matter.
Their stars orbit the galactic center, like those in the disks of spiral galaxies, but they do so in more random directions. Few new stars are known to form in elliptical galaxies.
The universe’s largest known galaxies are giant elliptical galaxies, which may be as much as two million light-years long. Elliptical galaxies may also be small, in which case they are dubbed dwarf elliptical galaxies.
Galaxies that are not spiral or elliptical are called irregular galaxies. Irregular galaxies appear misshapen and lack a distinct form, often because they are within the gravitational influence of other galaxies close by.
Number of Exoplanets
What is an Exoplanet?
An Exoplanet is a planet orbiting other sun or simply located in some other solar system. That Solar System may be in our galaxy or in some other galaxy of the universe.
If we broaden our scope there may billions of exoplanets. But, do you know, how many of those have we identified yet?
As per the report from Nasa on Exoplanets, there are more than 4000 exoplanets discovered and confirmed.
Saturn’s Moon Titan
Saturn has many Moons. If we look closure it looks like the Saturn has it’s own system like the solar system.
Titan is the largest moon of Saturn. If we compare in the whole of the Solar System, it the second largest natural satellite after Ganymede.
Cost of a spacesuit
Do you know, how much a spacesuit costs?
Well, it costs, 12 million US Dollars. The biggest share of it is its backpack and the control Module.
Its backpack and the control module itself costs around 70% of the total cost.
British astronomer Edmond Halley once predicted a comet. He predicted that the comet would return in 1758.
You won’t believe, the comet returned as Halley predicted. It has been 16 years of the death of Halley.
It was the first time that the arrival of a comet was predicted. This prediction was made by Edmond Halley that’s why the comet was named after his name. Now it is being called “Halley’s Comet”.
This comet can be visible after each 75-76 years. The last time it was visible from earth was 1986 and the Next arrival would be either in the year 2061 or in 2062.
Saturn is the most beautiful planet of our Solar System. Well, what makes it beautiful? It is its rings.
Its rings make the Saturn most beautiful planet of the Universe. How does its rings are made?
Well, its rings are made off Ice, dust and tiny rocks. These rings orbit the Saturn around its equator.
It looks like a ballet dancer is showing her skills by wearing ring on her waist.
No doubt, we are surrounded by many amazing and extraordinary facts of the universe. Here we have discussed 10 of them.
It’s not easy for us to always unaware of those extraordinary facts of the universe. They will somehow chase us and stick to us. we will be merely compelled to believe it to be true.
