PSR B1913+16
PSR B1913+16 is a special star that sends out a constant "tick-tock" sound that scientists can hear using special equipment. This sound is actually a signal that tells us a lot about the star itself and how it interacts with another star that is right beside it.
Think of it like playing catch with a friend. You throw a ball back and forth, but sometimes when the ball is thrown it might hit your friend's hand and bounce back a little bit. PSR B1913+16 is like one friend throwing a ball of light back and forth with another friend that's really close by. But, because these stars are super heavy and moving really fast, when the ball of light hits the other star it doesn't just bounce back a little bit, it actually causes the stars to move towards each other a tiny bit.
These movements are really small, but scientists can measure them and use the information to figure out things like how big the stars are, how fast they're moving, and even what they're made of! It's kind of like taking a really detailed photo to learn about something, but instead of using light to take the photo, scientists use sound waves.
Overall, PSR B1913+16 is a very special star that holds a lot of secrets that scientists are still trying to uncover. It might seem small and far away, but it actually holds a lot of importance for understanding how the universe works.
