In this illustration, the Milky Way is dotted with green bubbles, which highlight the places where life has spread beyond the solar system where it originated, creating a cosmic oasis, in a process known as panspermia. A new study hypothesizes that we may be able to identify the pattern of the Premium Lantern, if indeed it did occur. redit: NASA/JPL/R. Hurt We only have one example of a planet that is home to life - Earth. However, in the next generation, it may be possible to discover signs of life on planets orbiting distant stars. If we find life, new questions will arise, for example, did life arise spontaneously or did it spread from somewhere else? If life crossed the vast expanses of interstellar space a long time ago, how would we be able to tell? A new study by the Harvard-Smithsonian Institute for Astrophysics, concludes that if life could pass between the stars - in a process known as panspermia, it would spread in a characteristic pattern that we could potentially discover. redit: NASA/JPL/R.
