Okay kiddo, have you ever seen a laser before? It's a beam of light that can be very strong and powerful. Scientists use something called Laser SETI (Search for Extraterrestrial Intelligence) to try to find if there is life on other planets.
Laser SETI works like this - they have special cameras that look up at the night sky and watch for strong laser beams. They think that if there are aliens out there, they might be using laser beams to communicate with each other or even visit other planets.
So, the Laser SETI people are trying to pick up these laser beams and see if they're coming from another planet. They're kind of like space detectives, trying to figure out if there's anyone out there like us!
It's a really exciting science because it could mean we're not alone in the universe. And maybe one day, if we do find life somewhere else, we can meet them and learn about their world!
