Question 2

Process of Science: In the discovery of quasars, the radio source 3C273 was found to have strong emission lines at wavelengths that did not correspond to any known element on Earth.
 
  Suppose a scientist postulated that they had discovered a new element that only existed in these powerful radio sources. How would you test this?
