Life Cycle of Antares Antares is currently a Supergiant star, which means it is in the middle of its life cycle. The larger the star, the shorter its life will be. This means Antares will not live very long in star years. It started out from a large cloud of gas and dust called a nebula. 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.
