In a move that reveals that the world still hides many secrets, the site of the newspaper "Die Welt", German astronomers, has discovered three new planets outside our solar system, adding that one of these planets could live in the future.
Astronomers, including Germans from the University of Göttingen, have discovered the planets orbiting around the GJ 357 star, according to one of the German planets, one of the qualified planets hot because of its very high temperature.
The first observation of these planets took place in February using NASA's TESS satellite, one of the discovered planets, one of the discovered planets, GJ 357. b "is about 22% higher than the Earth.
"Although we can not live on this planet, it is a landmark for the exploration of Earth-like planets," said Stefan Drezler of the Institute of Astrophysics from the University of Göttingen.
Astronomers have called the rest of the planets GJ 357 c and GJ 357 d, he said, adding that the planet GJ 357 d was very cold and had a temperature of -53. The planet "GJ 357 c" has a mbad of at least 3.4 times the mbad of the Earth and its temperature is about 130 degrees.
Astronomers predict that in the future, the planet "GJ 357 d", which revolves around its star every 55.7 days, will be able to live at 20% of the distance from the Earth to the Sun, according to the second German channel ZDF.
The same source cited astronomers who said "if the planet" GJ 357 d "dense atmosphere, will require It is possible to conduct future studies to identify it because it could contain enough heat to warm the planet and allow the emergence of liquid water on its surface.

The first images of the planets of the solar system
Solar system
The solar system is composed of eight or nine planets, because only a few scientists consider Pluto to be a planet. The World Astronomical Union withdrew its recognition from Pluto Planet in 2006. The scientists were able to get the first close-up images of Pluto in 2015. The first images of Pluto were very old and date back to 1960.

Mercury
Mercury was the first astronaut to visit it in 1973. Mercury was the closest planet to the sun in the solar system and the distance from the sun is between 46 and 70 million kilometers. What the planet takes to turn around the sun is always uneven.

Venus is the second planet in the solar system near the sun. The Mariner 10 probe also sent this image in 1974, and the US Department of Space and Space (NASA) has increased the color depth of the image to display the clouds covering the atmosphere of the planet, consisting of carbon dioxide. The probe was exposed to several technical problems during its exploration of Venus, which lost a lot of energy.

Earth
The Earth is the third planet in the solar system in terms of distance from the sun. The first complete images of our planet were photographed by the lunar orbiter on August 1, 1966, three years before the first person landed on the moon. The Apollo trip to the moon has benefited from a series of photos taken by the lunar orbiter.

This image of Mars was the first image taken by a space probe. Mariner 4 took the picture on July 15, 1965. This image surprised scientists waiting for seas, valleys and mountains on Mars. The image showed the presence of nozzles on the surface of the planet similar to the craters of the moon.

The Pioneer 10 was the first image of the giant planet Jupiter, which was taken at a distance of 130,000 km from the planet in 1973. While NASA Juno was approaching 5,000 km from the planet in July 2016. Qatar The planet spans about 143,000 kilometers, the largest planet in the solar system, with a mbad of about two and a half times the total mbad of the solar system.

Saturn
Saturn is the sixth planet in terms of distance from the sun and the second largest planet after Jupiter. The Pioneer 11 wore this picture in 1979. The moon Titan, one of Saturn's moons, appears at the top left of the picture. The probe nearly collided with two moons of Saturn during the flight.

Uranus
These are the first images of the planet Uranus. The rings of the planet are visible on the image taken by the Voyager 2 spacecraft in 1986. Uranus is the coldest planet in the solar system and its temperature is minus 221 degrees Celsius. The "Pioneer 11" probe is crushed during Saturn's pbadage, forcing scientists to fix the remote camera from the ground.

Neptune
The Voyager 2 spacecraft also captured rare images of Neptune in 1989. Neptune orbits several cloud fields, the farthest from the planets, since Pluto is not part of the group. Neptune is 4.5 billion kilometers from the sun, 30 times the distance between the Earth and the sun.

Pluto
On July 13, 2015, the US Department of Aeronautics and Space (NASA) presented images of Pluto. Scientists celebrated the images of Pluto, although they are not considered a planet in the solar system. The New Horizons spacecraft also halted a five billion kilometer flight to the edge of the solar system to capture the situation.
