What is an alien probe?

 An alien probe is a hypothetical spacecraft sent by an extraterrestrial civilization to explore and study other planets or solar systems. The concept of alien probes has been a topic of science fiction for many years, but there is no concrete evidence that they actually exist.

In science fiction, alien probes are often depicted as autonomous machines with advanced artificial intelligence and technology, capable of gathering data and transmitting it back to their home planet. They may be designed to be stealthy and undetectable, or they may be equipped with powerful sensors and weapons.

In some cases, alien probes are depicted as being sent to Earth specifically to study humans or to make contact with us. These probes may be programmed with a set of directives or protocols, or they may be designed to make decisions based on their own advanced artificial intelligence.

While the existence of alien probes is purely speculative at this point, some scientists have proposed the idea of sending out our own probes to explore other star systems. These probes, sometimes called "interstellar probes," would be designed to travel vast distances and gather data about other planets and civilizations.
