Episode notes
Brightest Star Known
- The brightest star ever discovered is 8.3 million times brighter than the Sun.
- Stars like R136A1 burn hotter and faster due to their extreme mass and density.
Quasars and Blazars Brightness
- Quasars are trillions of times brighter than the Sun and emit powerful jets.
- When a quasar's jet points at Earth, it becomes a blazar, appearing even brighter due to relativistic effects.
Gamma-Ray Bursts Origins
- Gamma-ray bursts are the brightest explosions observed, emitting enormously high energy photons.
- They were first discovered by military satellites monitoring nuclear tests during the Cold War.
