The recording of an asteroid explosion began 170 years ago

NASA has captured great images of a giant star known as ETA Carina during its slow-motion gust. Surprisingly, the Hubble Space Telescope, with its Wide Field 3 camera, emits ultraviolet light as well as flammable and bright star gases, while red, white and blue glow.
And ETA Carina, is the biggest star of the binary solar group, and astronomers think she weighed more than 150 suns.
The glow of the star began 170 years ago when she was hit by a gigantic explosion, dubbed Big Bang, making her the second brightest star in the world for over a decade.
ETA Kareena remained so glamorous for a moment that he became an important star in the navigation charts of South Sea sailors.
But the star has faded since its explosion, and it is now difficult to see it with the naked eye. Astronomers have been speculating for decades that he is on the verge of destruction.
But the glow of the star is not over, which means that it still exists, which is recorded by the Hubble Telescope.
The explosion took the form of a group of cages with dust balloon, gas and other reflections of the explosion of the star.
The blue color of the images is the result of ultraviolet radiation, due to the inflammation of the magnesium contained in the gas.
However, astronomers who studied the images were surprised to find gas in places never seen before in the interstellar areas of gas and dust balloons, as well as in other bright red glow.
"We have discovered a large amount of hot gas emitted by the large eruption, but the material surrounding Eta Carina has not yet been touched," said Nathan Smith, of the Steward's Observatory. University of Arizona.
Smith explained that most of the gas emissions had been located in places that scientists thought were empty cavities, but that these emissions are fast and increase speculation about the energy of a gas explosion. already powerful stars.
He pointed out that the newly discovered gas is important to understand the beginning of the explosion, because it represents a fast and active matter emission, perhaps expelled by the star shortly before the day. explosion.
However, astronomers still need more monitoring to measure the speed at which these emissions move and when they are deprived of food.
Scientists use ultraviolet light research technology for hot gases to study other stars and gas clusters called nebulae.
