The solar system fits in 'bubble'

A series of supernova explosions, though not strong enough to kill life on earth, have "wrapped" the solar system in a hot air bubble and exist today.

According to scientists, 10 million years ago, a series of supernova explosions "blew" a giant bubble into the interstellar environment in space. This area is called "Local Bubble" , Daily Mail reported.

Astronomers recognized the "Local Bubble" region in the 1970s and 1980s. However, its existence is still controversial.

Meanwhile, astronomers began to detect radiation from X-rays around the earth. This suggests that most solar systems are emitted by radiation from supernova explosions around interstellar space. Although explosions are not strong enough to destroy life on earth, they "wrap" the solar system in a hot air bubble and survive today.

To prove the hypothesis, in December 2012, researchers from the University of Miami, USA, launched a scientific experimental rocket from the launch of White Sands in New Mexico state into space. The rocket carrying an X-ray detector reached a height of 260km and moved over the atmosphere for 5 minutes. The results showed that 40% of the X-rays detected were derived from the solar system. According to the researchers, the remainder comes from the "Local Bubble" , the area left behind by the supernova explosion.

"This is an important finding. It helps us better understand the galactic region near the sun . Discovering is the basis for future models of galactic structures , " said Professor Massimiliano Galeazzi. know, and shared that he and his colleagues planned the next launch of the X-ray detector in December 2015.
