Astronomers recorded the most powerful explosion of a supernova in a previously unknown galaxy
In the vastness of what is there. Galaxies, star clusters, nebulae, star systems, planets — billions of different celestial bodies live in space your life. Only one of the types of stars in the observable Universe there are more than 10. Among them are red and white dwarfs, pulsars, brown dwarfs, neutron stars and . Speaking of supernova. It is through the explosions of these special stars there is life on our planet. And even you and me. Recently, scientists have discovered the largest supernova explosion in the entire history of observations. Moreover, supernova SN2016iet completely contrary to the understanding by scientists of how supernova should behave.
What is a supernova?
Among the different types of stars, supernovae stand out much. In the first place because they are very massive, and their brightness occasionally exceeding the brightness . As you know, every star has a life cycle. When the life of a supernova comes to an end, it explodes. The flash from the explosion of this type of stars can be so bright and strong that its power exceeds the explosions of other stars. Scientists explain that the processes that occur in supernovae at the latest stage of their evolution.
After the explosion of a supernova in space gets a tremendous amount of energy and chemical elements necessary for our life. In other words, the stars died for us. In addition, the explosions of stars are some of the most spectacular and powerful phenomena in the Universe.
looks like a conventional explosion of a supernova
In November 2016, the Gaia satellite of the European space Agency has discovered something intriguing. Astronomers used observational data over the past three years in an attempt to understand what they saw. Supernova Sn2016 defied their expectations. His research astronomers published in .
Unusual supernova
According to scientists, they observed the remnants of the most massive star destroyed in the explosion. SN2016iet unusual. This supernova has a large amount of energy, duration, unexpected chemical signatures and is not metal-rich environment. It's not like any of the things astronomers have seen before.
Initially, the researchers decided that data errors. However, according to lead study author Sebastian Gomez, a graduate student at Harvard University, after some time, scientists have determined that SN2016iet — it's an incredible mystery, located in a previously not registered in a galaxy a billion light years from Earth. For observations of the supernova has been used many telescopes, including telescopes from around the world.
Astronomers say this supernova is different — how it eventually changes the brightness, its spectrum, in which it is located, and even the location of the supernova in the galaxy is also unusual. Edo Berger, Professor of astronomy at Harvard University and co-author of the study said that sometimes astronomers see a supernova, which is unusual in any one aspect, but otherwise no different from an ordinary supernova. However, the star SN2016iet unique in all respects.

Before the explosion of mass SN2016iet was 200 times the mass of our Sun. Astronomers believe that it was formed by itself in 54 000 light years from the center of the dwarf galaxy. That itself is strange and unusual. From the point of view of lifetime of the star, this was short. The supernova lasted only a few million years, losing during this time 85% of its mass. Then, when the star exploded, its debris collided with the material that the star was thrown out over time, creating a strange kind of supernova that astronomers observing today.
What is a pair of a supernova?
Scientists believe they have received the first proof of the existence of steam-volatile supernova. For decades, astronomers assumed the existence of such stars, but until today the evidence was not discovered. Pair-instability supernova — it is a rare type of incredibly bright stars. After the explosion these stars dissipate in the space around the iron in an amount of up to 10 solar masses. In addition, scientists believe that SN2016iet is a way to die the most massive stars in the Universe.
Today, astronomers continue to observe this unusual star to learn more about how it was formed and how it might change in the future. Most of the supernova to disappear and become invisible on the background glow of galaxies-the home within a few months. But since SN2016iet very bright and isolated, scientists can study it for years.
