The vast universe contains many mysteries waiting to be discovered. How many stars in the universe, the earth is shaped ... are the mysteries of the universe has a strong attraction to all those who love exploring the universe. The interesting revelations about the universe below will hopefully inspire passion, explore the world around you.
- It is possible to have more than 500 million planets in a living galaxy
The planets can meet the minimum need for life where temperatures need to be at acceptable levels, water exists in both liquid and gaseous states, with the combination of chemicals available to build life.
According to scientists, there are more than 500 million planets in the galaxy that can meet those needs. They call planets in the habitable zone of a star, "Goldilocks Planets."
If this is correct then the potential for extraterrestrial life is enormous.
2 . All galaxies, planets and stars account for only 4% of the universe
All that we see in space is only 4% of the universe, the other 96% we can not see. We can not even determine what the rest of the universe is. Some scientists call it dark energy or dark matter.
With mathematical formulas, we can estimate the gravitational force of these realities, which is theoretically, there is no way to decipher them. That remains a mystery to challenge the scientists.
3 . The solar system takes 225 million years to orbit the Milky Way
The Milky Way is a spiral galaxy that resembles a wreath and is always spinning. It is spinning at about 168 miles per second (269 kilometers per second) or about 600,000 miles per hour (960,000 kilometers per hour). The solar system is about 28,000 light-years from the center of the Milky Way and it would take 225 million years to orbit the Milky Way.
4 . Is there a "human cannibal universe"?
The definition of "human cannibalism" is to indicate that a galaxy collides with a star or planet and "swallows" them.
The Andromeda Galaxy (or galactic galaxy), the spiral galaxy closest to our Milky Way galaxy, has been suspected of becoming a "predator" that has "gobbled" smaller galaxies and more distances. close to it.
According to Alan McConnachie of the Herzberg Institute for Astrophysics, "there is evidence that Andromeda's" leftover food "is the remnant of the stars and tiny galaxies that are too close. with this "giants".
5 . Days on Earth began longer
By convention a day is equal to the time that Earth orbits its axis. Earth's daily average increases by a few milliseconds per year but the rotation of the Earth's axis is influenced by many factors including the luminous effects of the Moon.
In addition, disasters such as earthquakes or tsunamis can affect the rotation of the Earth's axis and they can add or remove a few milliseconds that day on Earth increases each year.
One example is the 2011 Japan Earthquake that shortened our day to 1.8 million seconds. Since the days on Earth are continually prolonged, it is estimated that the dinosaurs still exist, the Earth date is only about 22 hours.
6 . The sunlight that hits your face is more than 30,000 years old
So far, the Sun is estimated to be 4.6 billion years old and is undergoing the last 5 billion years before burning up helium, becoming a giant red star. After about a billion years as a red star, the Sun will shrink as a white dwarf.
The sun's rays take about eight minutes to travel through 93 million miles (150 million km) to Earth. These rays, though, were formed over a period of more than 30,000 years ago at the core of the Sun through a high level of nuclear fusion as the Sun consumed helium and hydrogen.
7 . Ability to have more than one universe
The view that we are living in the universe that is one of many existing universes is increasingly accepted. It is derived from the theory of eternal inflation. This theory suggests that after the Big Bang explosion, space and time expanded at different speeds and in different places. This can lead to the existence of individual bubble universes.
Many scientists have proposed the existence of parallel universes.
8 . Are we made of the dust of the stars?
Earth was born from the Sun. This nebula consists of hydrogen and helium created from the Big Bang and other heavier elements made from dead stars.
"The nitrogen in our DNA, the amount of calcium in our teeth, our iron in our blood, all made from the dust of the dead stars," said researcher Carl Sagan.
If you look up at night sky stars, think of the deep connection between us and them. If not for the death of the stars we will not have life.Earth was born from the Sun. This nebula consists of hydrogen and helium created from the Big Bang and other heavier elements made from dead stars.

9 . About 4,800 stars are produced per second
In a galaxy, the total mass of stars formed in a year is equivalent to about three solar masses (the mass units used in astronomy to determine the mass of stars or large bodies).
The unit of mass of the Sun is essentially the mass of the Sun and is equivalent to the source of enough material to form about three suns per year. That means that each day there are about 150 billion or 400 million stars formed equal to 4,800 stars produced per second!
