Technosignature

Technosignature is a way to look for signs that there is another type of technology existing in the universe besides what humans have created. Scientists use special instruments to look for things like radio waves and light that could come from a species that is not from our planet. Scientists also look for events that happen in space, such as exploding stars. When they look for these things, they are looking for signs that tell us if there is something out there!
