10 unbelievable discoveries in the universe

Exploring the universe is always the desire of people to learn about the world outside the earth. In that journey, people discovered important objects in the universe that marked the culmination of wisdom and far beyond human imagination.

Extreme asteroids

In early 2013, the Kepler Space Observatory (NASA, USA) discovered a star system of three planets, including one outside the Solar System that is considered to be the smallest until time. present. This asteroid pole is named by scientists as Kepler 37-b . Its size is smaller than Mercury and is only 200km larger than the moon's diameter. According to scientists, most planets outside the Solar System are much larger than Earth, and are usually the size of Jupiter.

All three planets orbiting a yellow star like the Sun, located 210 light-years from Earth. The temperature on the surface of this tiny planet reaches 420 degrees Celsius, making water and life impossible to survive.

Based on their small size and overheating surface, astronomers consider the planet Kepler-37b does not seem to have an atmosphere . Along with that, Kepler-37b only took 13 days to complete an orbit around the parent star.

Super giant Fermi bubble of the Milky Way

If we rotate the Milky Way horizontally, we will see giant Fermi bubbles stretching across the North and South planes of the center of the Milky Way. The Fermi bubble is two super-giant globules , up to 50,000 light-years in diameter, equivalent to ½ of the Milky Way's diameter. A beam of light with a velocity of more than 1 million km / h will take up to 50,000 years to be able to move from this gamma-ray "bubble" edge to the remaining gamma-ray edge.

NASA astronomers have so far not found the origin of the Fermi bubble. Hypothetically, the Fermi bubble formed from the gas erupting from the supermassive black holes in our Milky core.

Theia

More than 4 billion years ago, our original Solar System looked very chaotic and extremely dangerous. At that time, in the Solar System only scattered stones and ice, so the collision occurred very often.

One of the most popular theories about the birth of the Moon is thought to have originated in one of these maximum collisions. According to scientists, the original Earth collided with a planet of the same size as Mars. After the remaining debris collision was in the Earth's orbit and formed the Moon as it is today.

If the collision occurs more directly, or closer to the two poles, or the equator, there is another outcome. At that time, the Earth must have been completely erased.

Sloan giant galaxy wall

The Sloan Great Wall (Sloan Great Wall) is a super-giant galaxy wall , gathering hundreds of millions of large and small galaxies in the universe. This is considered one of the largest structures in the universe so far, with a diameter of up to 1.4 billion light-years. According to scientists, the Sloan Great Wall is a direct result of the Big Bang and can be observed under short wavelengths .

Minimal black hole

There is nothing more frightening and dangerous than the black holes in the universe, they are dubbed the " death holes " or "horrifying killer " in the vast universe. Astronomers have discovered many supermassive black holes , billions of times larger than the Sun. If the black hole was discovered by astronomers previously with a mass of 14 times that of the Sun, this minimum black hole is only 3 times larger than the Sun. The scientific name is IGR , this black hole belongs to the Scorpion constellation in the Milky Way. Although small, the black hole IGR can still easily attract planets when straying in space.

Ultra small galaxy

Galaxies are known for their giant structure, which gathers trillions of stars interspersed with dust, gas and dark matter. However, in 2009 American scientists discovered a tiny galaxy called Segue 2 . This dwarf galaxy contains only about 1,000 stars, becoming one of the smallest and faintest satellites in our Milky Way galaxy.

The discovery of Segue 2 has a great significance for mathematics and astronomy, helping us better understand the formation of galaxies and add evidence of the existence of black holes .

The largest impact system of the Solar System

Since we embarked on a thorough study of Mars , there has been a lot of controversy regarding finding out why the surface of Mars is so irregularly irregular. The reason for this is because, according to scientists, the largest solar system is found on the Borealis basin of the northern hemisphere in Mars. This hole is up to 8,500 km (40% of the area covered by the Martian surface). The second largest impact crater The Solar System is also in Mars but is 4 times smaller. Scientists conclude that, in order to have such a large crater, objects that collide with Mars must be larger than Pluto.

The most recent point in the Solar System

Scientists have discovered asteroids whose scientific name is 2000 BD19 is the closest object to the Sun compared to other planets, especially Mercury, in the solar system. Because it is near the Sun, asteroids with this smallest orbit have tremendous heat. The temperature at 2000 BD19 can melt zinc and lead. Thanks to the discovery of this most recent asteroid, scientists have taken a step forward in understanding the factors that can change the trajectory of a planet, which can then be studied in detail. objects closer to Earth.

Very old quintessence

Quasars are the brightest and most distant objects in the visible universe, they are also called 'star-like sources of radiation' . Astronomers discovered a quasar and named it ULAS J1120 + 0641 . ULAS is considered the oldest standard in the universe. It appeared about 800 million years after the Big Bang . It is known that quasars originate from super heavy black holes , flying in space at 240,000 km / sec, equivalent to 80% of the speed of light.

Saturn's Titan moon

The Cassini space probe once sent to Earth the magnificent images of Saturn's moon Titan surface. This 1000km area of ​​the Northern Lunar Pole, without water, exists but is filled with liquid methane and ethane. Titan is Saturn 's largest satellite, 50% larger than the Earth's Moon. Because of the special atmosphere, mostly nitrogen, scientists are taking a lot of time to understand its origin.
