In the vast expanse of space, stars are constantly vibrating due to sound waves traveling through their interior. These waves can ripple around the entire circumference of the star or dart right through its core, and they can be detected by scientists studying them. In the Sun, for example, a typical wave completes one cycle in just five minutes.
Red giants, which are much larger than the Sun, have lower-frequency waves that can last for weeks to months. By studying stars of different ages, scientists can gain insights into what will happen to our own Sun as it ages. This research provides valuable information about the internal structure and evolution of stars.
Analyzing these sound waves allows scientists to better understand the life cycles of stars and how they change over time. Through this study, we can gain a deeper understanding of the universe and our place within it.
