Astronomers have searched the entire Milky Way galaxy to identify safe places to live. Looks like we’re in a good place.
But if the current plague wants you to breed on another planet, new research suggests, it would be better to go to the center of the galaxy.
The new discovery was made by a team of Italian astronomers studying the location where a powerful cosmic explosion was killed. Explosions like supernova explosions or gamma rays create particles and radiation that break up DNA and destroy life. Therefore, the most habitable areas should be areas that are free from frequent eruptions.
“The powerful cosmic explosion should not be ignored. These events play a life-threatening role in the Milky Way galaxy, ”said Ricardo Spinelli, lead author of the study and astronomer at the University of Inspia in Italy.
In the youth of the Milky Way, the edges of the galaxy are safe
Astronomers have not only discovered the most dangerous place in the galaxy, they have also identified the safest part of the Milky Way in its 11 billion year history. The results show that we are currently on the threshold of “big residential real estate”. But in the Milky Way’s youth, the edges of the galaxy were safe.
Many factors make a planet habitable. For example, a planet must be in an “Ecosystem” (ZLC), where the temperature and activity of its host star are neither too high nor too low, but perfect. In addition, the galaxy of life has to deal with harmful radiation from outer space.
Fierce cosmic events, such as supernovae and gamma-ray bursts, throw particles into space at the speed of light. Not only can they kill all known life forms, these particles can also erase the planet’s atmosphere. After such an event, scientists hope there will be no traces of life on planets orbiting nearby star systems.
Our galaxy is becoming increasingly friendly
“For planets close to stellar eruptions, complete contraception can be trusted. For those who are at a greater distance, the mass damage is greater, “said Spinelli. Direct science.
The authors also write that gamma-ray eruptions may have played a key role in the Artevician-Silurian mass extinction 450 million years ago, the second largest mass extinction in Earth’s history. Although there is no conclusive evidence, researchers believe that this is possible with respect to Earth’s position in the galaxy.
Until 6 billion years ago, most galaxies were sterilized by violent eruptions. As the Milky Way galaxy ages, such eruptions become less frequent. Fortunately for us, our galaxy is becoming increasingly friendly. In the future, there will be fewer cases of mass disappearances and they will be less serious.
