Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! A new study suggests a terrifying possibility: our signals to Mars may have put us on an interstellar map for all to see. So let's review past signals we have sent to space with the infamous arecibo observatory, signals we have received aka the mysterious "wow" signal, and everything you need to know about radio leakage and the waterhole - the frequency range where we are most likely to detect life.
