10 Biggest Things in the Universe

10 Biggest Things in the UniverseOur 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.

Solar system

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.

Comets of the centuries

In the fall of 2020, after Amateur astronomers Vitaly Nevsky and Artem Novichonok first observed the comet ISON, astronomers had expected that she would become a “Great comet” − a rare visitor, perhaps the brightest comet of the twenty-first century.

Alas, severely battered during the close approach to the Sun in November of this year, ISON no longer promises such a bright future. To the naked eye from the Ground to see it would be impossible − but hopes not worth it to lose. Somewhere in the dark depths of space, probably unnoticed by anyone else is racing the comet, which will deserve the attention and present us with an unforgettable sight. This has always been the Large comets appear about once a decade, and every century one of them was especially bright.

Comet ISON

We will tell you about these “comets of the century”, since the sixteenth century. It is interesting that they flew as a rule, in the second half of your century, and has had an average of once every 97 years. Given this, we can calculate that if the comet of Ikeya-Seki (C/1965 S1) visited the Earth in 1965, following a visitor, you can wait until 2029.

However, to predict what particular impossible: a Big comet can appear quite unexpectedly, at almost any time. The message we may hear tomorrow.
