4. Origin and Usage:
The word "nova" comes from the Latin "novus," meaning new. Novae are astronomical events that occur in binary star systems, where one star is a white dwarf and the other is a main-sequence star. The white dwarf pulls material from the main-sequence star, which accumulates on its surface until a thermonuclear explosion occurs, causing the star to suddenly increase in brightness. Novae have been observed by humans for thousands of years, and they continue to be an active area of research in astronomy.
