Four Ways Astronomers See the Invisible: How Black Holes Are Actually Studied
Astronomers study black holes indirectly using four principal techniques: tracking stellar motion, detecting X-rays from accretion disks, radio interferometry imaging, and listening for gravitational waves. Each method reveals different physical phenomena and properties, making a combined approach essential for understanding these elusive objects.
