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.

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.

A scene from the upcoming film “the Martian”.
In the United States selected an international team of scientists from six volunteers to participate in a new experiment simulating conditions on Mars. Within 365 days they will be completely isolated from the outside world on the slopes of a sleeping volcano Mauna Loa in Hawaii, which resembles the landscape of the red planet.
This is the fourth such experiment in 2020. The first two groups was in seclusion in self-contained complex in Hawaii for four months, the third managed to survive in isolation for up to twice as long – eight months. New group aims to raise the bar, “duration of survival” in the conditions simulating the Martian, to a new level. By the way, the experiment begins next week – August 28.
“The longer becomes each mission, the better we understand what are the risks from space travel,” said scientific project Manager Kim Binsted.
The organizers of the experiment hope that it will help to prepare the first manned Martian mission, which, according to estimates of NASA, will take place in 2030-ies. Continue reading
