Astronomers have searched for the safest place in the Galaxy and found the best spot. According to the new research, the past year has seeded the thought of relocating to another planet so people might look at the center of the galaxy.
Italian astronomers made research about the locations where powerful cosmic explosions may have killed off life. These explosions, such as supernovas and gamma-ray bursts, spew high-energy particles and radiation that can shred DNA and kill life. Regions that are more hospitable to life will be the ones without frequent explosions. Riccardo Spinelli, an astronomer at the University of Insubria in Italy and the lead author of the study said that the cosmic explosions are not negligible for the existence of life in our galaxy throughout its cosmic history.
The Italian astronomers also identified the safest places in the Galaxy. Many factors make a planet habitable. Every planet needs to be in a Goldilocks zone, where heat and activity from their host star aren’t too much or too little, it must be perfect. But in addition to these local conditions, life also has to combat harmful radiation coming from interstellar space.
The gamma-ray burst may have played a leading role in the Ordovician mass extinction event around 450 million years ago. About 6 billion years ago, the Galaxy was regularly sterilized by massive explosions. As it became old those explosions reduced. Today, the mid regions, forming a ring from 6,500 light-years from the galaxy’s center to around 26,000 light-years from the center, are the safest areas for life. Closer to the center, supernovas and other events are still common, and in the outskirts, there are fewer terrestrial planets and more gamma-ray bursts.
