This review describes obervations of hot coronae around early-type galaxies. The observations show that early-type galaxies have 0.5-4.5 keV luminosities up to nearly 10 to the 43rd ergs/sec dominated by thermal emission from 10 to the 10th solar masses of hot (about 10 to the 7th K) gas. Calculations which model the evolution of the coronae are presented. These models can explain the present epoch observations as well as predict the coronal properties at large redshift.
