Summary:
- NASA's exoplanet-hunting spacecraft, TESS, has detected a unique phenomenon - a red giant star "singing" to its partner black hole.
- The red giant star is pulsating and sending out vibrations that can be detected by TESS, providing insights into the star's internal structure and its interactions with the black hole.
- This discovery helps scientists better understand the complex relationship between stars and black holes, and how they influence each other's behavior over time.
