Stellar phenomena refer to various events and processes that occur in stars and their environments. These include the birth of stars from clouds of gas and dust, their life cycles, and their eventual death, which can result in spectacular explosions known as supernovae. Other phenomena include the formation of nebulas, which are colorful clouds of gas and dust, and the creation of black holes when massive stars collapse. Additionally, stellar phenomena encompass the interactions between stars, such as binary star systems, where two stars orbit each other. Pulsars, which are rapidly spinning neutron stars emitting beams of radiation, and solar flares, sudden bursts of energy from the surface of the Sun, are also fascinating examples of these cosmic events.
