Space probes are unmanned spacecraft designed to explore planets, moons, asteroids, comets, and other objects in our solar system (and even beyond). They collect information using cameras, instruments, and sensors, then transmit that data back to Earth via radio waves.

Some famous examples include:

* Voyager 1 & 2: These probes have travelled further than any other human-made objects, leaving our solar system and entering interstellar space.

* Juno: Currently orbiting Jupiter, sending back incredible images and data about the giant planet.

* Cassini: Orbited Saturn for 13 years, studying its rings and moons.

* New Horizons: Flew past Pluto and is now exploring the Kuiper Belt.
