Episode notes
Voyager 2 Reconnection
- NASA lost contact with Voyager 2 after sending a faulty command.
- They re-established contact by sending a stronger signal, essentially "shouting" across billions of miles.
Voyager Missions
- Voyager 1 and 2, initially designed for a four-year mission, now explore interstellar space.
- They carry golden records containing images, music, and greetings, intended for potential extraterrestrial life.
Trumpetfish Shadowing
- Trumpetfish use a hunting technique called shadowing, where they swim closely behind other fish.
- Researchers used 3D-printed fish models to study this behavior and found it helps trumpetfish get closer to their prey.
