In the universe there is a huge number of luminous astronomical objects. There are so many that they can not be counted. Such objects are found in our galaxy, and there are hundreds of billions of them, scientists say. What are the brightest objects in the universe? Description and characteristics of some of them will be presented in this article.
Quasars
Considering what is the brightest object in the universe, you should pay attention to quasars. They belong to the class of astronomical objects, which are the most striking (in absolute terms) in the part of our Universe visible from the Earth.
According to scientists, the quasar is the active core of the galaxy, only at the initial stage of its development. In it, a black hole with super mass absorbs the surrounding material and forms the so-called accretion disk. It is he who is the source of the brightest radiation.
Studying the brightest objects in the Universe, scientists were able to establish the approximate radiation power of quasars. To imagine how bright they shine, an example should be given. So the quasar, called R136a1, is brighter than the Sun by almost nine million times. This is not the largest object of space in volume terms, but it is 256 times heavier than the Sun.
Description
From a photo of the brightest objects in the Universe, it is impossible to assess the strength of their brightness. However, scientists were able to do this with the help of calculations and created a special scale. According to her, the brightness of our Sun is 4.8 m, and the quasar R136a1 - 8.7 million solar brightnesses.
In addition to its colossal brightness, quasars give the strongest electromagnetic radiation. Only due to the fact that these stars are hundreds of light years away from us, planet Earth still exists.
Also, quasars are unique in that perishing, they form a supernova or hypernova. During the explosion, a huge amount of light and nuclear energy is released. In these few seconds, such an amount of light and energy is produced that our Sun would give in 10 billion years.
Conclusion
Studying the brightest objects in the Universe, it is necessary to talk about the theory that is put forward with regards to them. So scientists suggest that the light and energy emitted by quasars at the time of the birth of the hypernova (huge explosion), and an incredible amount of gamma radiation spread throughout the galaxy, thereby affecting everything with which they “come into contact”.
Among the brightest objects in the Universe is the first 3C 273 quasar discovered, which has an absolute value of -26m, which indicates its incredible brightness. He is four trillion. times brighter than the sun. These incredible meanings are very hard to imagine. It is even more difficult to say how much gamma radiation and light this quasar will produce at the time of the explosion, and what consequences it will entail.
To date, scientists only solve all the secrets that are hidden from man in space. What happens in other galaxies is hard to imagine. It is known that the supernova that we can see today was formed hundreds of years ago. Due to the fact that quasars are located at huge distances from the Earth, mankind is observing these processes only now.
