Scientists can use cosmic background radiation to look at the earliest moments of the universe and they look around at the galaxies near our own to study its recent history. But it is the in-between period, known as the “teenage years” of the universe that is difficult to study. Scientists are hoping that the newly developed “spectral siren” method can help them do exactly that.
