Celestial body is the brightest invisible universe before the naked eye

A type of quasar called blazar is still a great mystery for scientists because of their difficult-to-explain light-emitting mechanism.

According to astronomers at Boston University, America, the universe is not an eternal night, but it is filled with light from mysterious objects called blazar. However, the radiation emitted by these blazars is not visible light but invisible radio waves and gamma rays to humans.

Blazar is a small quasar that emits powerful gamma rays and radio waves at the center of a giant elliptical galaxy. When the first blazar was discovered in 1962, astronomers were extremely confused. They do not know what it is and have never seen anything similar. So far, astrophysicists have observed thousands of blazars in the universe, The Epoch Times reported on February 22.

Researchers at Boston University are trying to understand how blazar shines and where they get energy. The most acceptable hypothesis is the blazars that take energy from a supermassive black hole that is hundreds of millions more massive than the Sun.

The problem is why energy can move from black holes to blazars while the gravity of black holes is so strong that even light cannot escape. According to scientists, black holes swallow everything that is near it. When the amount of material absorbed is too large, they will friction in the middle of the black hole and heat up and reverse the charged particles, magnetic fields and other radiation.

When one of the radiation is directed at Earth, the telescopes acquire them in the form of a blazar."Black holes suck almost everything from their surroundings, but somehow they also emit outside," said Alan Marscher, a professor at Boston University.

Even so, the blazing phenomenon of blazers still has many mysteries. Astrophysicists predict that all gamma rays come from the black hole in the center of blazar. However, in recent observations, the Marscher's team discovered that the majority of gamma rays emitted from a light-distant black spot several years ago.

This strange fact leads scientists to a new set of ideas. With the help of computers to simulate experiments, they hope to soon be able to conduct verifiable observations with modern telescopes.
