“Corona”Virus eh? Pretty flippin’ slick!
Corona: The glow around a conductor at high potential.

A Cepheid variable (/ˈsɛfiːɪd, ˈsiːfiːɪd/) is a type of star that pulsates radially, varying in both diameter and temperature and producing changes in brightness with a well-defined stable period and amplitude. … This discovery allows one to know the true luminosity of a Cepheid by simply observing its pulsation period.
