Flashcards
Front shock waves
Front shock waves
Powerful waves of energy released when a supernova explodes. They travel outward, pushing against the surrounding interstellar gas.
Reverse shock waves
Reverse shock waves
Waves of energy that travel backward towards the center of a supernova explosion. They form as the outward shock waves interact with the expanding outer layers.
Interstellar medium
Interstellar medium
The gas and dust that exists between stars in the galaxy.

Study Notes
Supernova Explosion Shock Waves
- Supernova explosions send powerful shock waves into the interstellar medium (ISM).
- These front shock waves carry tremendous energy, heating the surrounding gas significantly.
- Reverse shock waves travel back towards the explosion's center.
- Expanding outer layers of the supernova entrain/drag surrounding material from the star.
