How to survive in the galaxy
Recently, astronomers have mapped out the most suitable environment for life in the Milky Way in the past 13 billion years. The Milky Way is a dangerous place, full of stars and gamma-ray bursts, which may strip off the atmosphere of a planet and threaten life on the planet. An analysis showed that the safest areas around the galaxy have moved from the periphery to the center of the galaxy over time.
