Radio signal from HD 164595

HD 164595 is a star located about 95 light-years away from us. Its radio signal was detected by a large radio telescope in 2015. Radio signals from stars are kind of like light coming from them, but instead of being made of colors that we can see, it's made of sound waves like a cell phone signal. This signal is really interesting because it is the first signal detected from a star that has been seen with a radio telescope like this, which means it's the first signal from something far away that we have detected with this kind of technology. It might mean there's something interesting on a planet around this star, like maybe some kind of life that is sending out a signal. That's why scientists will keep looking to see if they can find something to explain why this signal came from HD 164595.
