Astronomy Quote by Andrea M. Ghez
“There's a large cluster of stars that are orbiting the center of our galaxy. And by measuring the motion of stars, and in particular, their orbits, we can figure out whether or not there's a central black hole.”
About This Quote
Observing stellar orbits around the galactic center allows scientists to infer the presence of a central black hole through gravitational effects.
In simple terms: Star motions reveal a central black hole.
Key Takeaway
Use orbital data to detect massive objects.
