Data from the WISE infrared telescope clearly indicate the existence of a ninth planet in our Solar system – scientists at the University of Louisiana are absolutely sure of this.
Astronomers believe that in our solar system there may be an incredible number of celestial bodies of different sizes, about which we know almost nothing. This includes planets and comets that move in long-period orbits. Proof of the existence of such objects will be crucial for all earthlings. Now scientists are on the threshold of the discovery of the Millennium, because they believe that they have discovered the ninth planet Tyche, which by all calculations should exist in our star system!
So it exists! But where did this most mysterious planet come from and why couldn’t it have been found earlier? It’s all about the Oort cloud, whose existence has been proven only theoretically. Astronomers believe that this is a giant cloud located at a distance of up to 1 light year from our Sun, which contains trillions of celestial bodies of large and small sizes. When the outer edge of the cloud is affected by the gravity of passing stars, celestial bodies break out of their orbits and rush through the universe. At the same time, their trajectory necessarily passes through our solar system. This is how comets appear within our borders. Continue reading
Our universe is really huge. Pulsars, planets, stars, black holes, and hundreds of other objects of incomprehensible size that are located in the Universe.
And today we would like to tell you about the 10 biggest things. In this list, we have compiled a collection of some of the largest objects in space, including nebulae, pulsars, galaxies, planets, stars, and more.
Without further delay, here is a list of the ten biggest things in the Universe.
10. The largest planet.
The largest planet in the Universe is TrES-4. It was discovered in 2006, and it is located in the constellation Hercules. A planet called TrES-4 orbits a star that is about 1,400 light-years away from the planet Earth.
The planet TrES-4 itself is a sphere that consists mainly of hydrogen. Its size is 20 times the size of the Earth. Researchers claim that the diameter of the discovered planet is almost 2 times (more precisely, 1.7 times) larger than the diameter of Jupiter (it is the largest planet in the Solar system). The temperature of TrES-4 is about 1260 degrees Celsius.
9. The huge star. Continue reading
Solar system. Planets of the solar system
Its center is a huge star called the Sun. It is the closest star that is billions of years gives us light and heat. Without it, impossible would be life on the planet. Around it revolve the planets, of which eight are known today, as well as other celestial objects.
Schematically, the structure of the solar system is as follows:
Man is always interested in the question thus arose our solar system. But it was a long time before scientists were able to answer this question. There were many versions and assumptions on this issue. And today, astronomers are continuing their investigation.
According to a hypothesis of Kant-Laplace five billion years ago there was only a gas cloud. It moved through the universe, but at some point he undergoes certain processes. Then there is compression and then begins the rotation, the center of rotation is the fastest. The temperature at the center of the cloud began to grow and formed a protostar that later became the Sun. The nebula continued to spin, and the star are unable to absorb all the substance of the nebula, they are attracted, experienced, forming planetesimal. One of them appeared on the planet.
