Supernovae such as this one, named SN 1993J, give off blasts of cosmic rays that bombard the Earth and change the atomic make up of its surface rock. Researchers supported by the international CRONUS project will measure the effects of cosmic rays to determine the timing of ancient geologic events. The color scale represents the brightness of the radio emission detected by very large array radiotelescopes. Blue depicts the faintest emission; red depicts brightest.
