Corona is a Spanish word for crown and is commonly used to describe the crown-like appearance of the sun's corona during a solar eclipse. It refers to the outermost layer of the sun's atmosphere, which is only visible during an eclipse or by using specialized equipment. In recent times, the term "corona" has become widely recognized due to the global COVID-19 pandemic caused by the novel coronavirus. The virus was named "coronavirus" because of its crown-like appearance under a microscope, with spike proteins surrounding its surface. As a result, the term "corona" has taken on new significance and is now associated with the pandemic that has affected millions of people worldwide.
