SUMMARY: Living at the centre of the Milky Way would be beautiful, but dangerous, according to research from the Harvard Smithsonian Center for Astrophysics. Every 20 million years or so, a ring of gas and dust 500 light-years away from the middle of the galaxy collapses, beginning a furious period of star formation, which then sets off a series of supernovae. A planet in the area would be completely sterilized of life as star after star explodes. The next starburst period in the Milky Way is likely to happen in about 10 million years, but don't worry, we're far enough away that nothing would happen to the Earth.
