Antares was born when the gas and dust became so dense and hot that nuclear fusion began and formed a protostar. It then changed into a massive star. Antares proceeded to its current stage as a supergiant. As it continues its death cycle, its next step will be to become a supernova and explode. The bottom cycle is Antares’s.
