Ever thought about how far our TV, radio, and radar signals have traveled? Turns out, Earth’s radio “bubble” is now 238 light-years wide! That means any aliens chilling near Proxima Centauri could already be tuning in to our cosmic mixtape. Most of our signals are just background noise by the time they get that far, but a few powerful transmissions could be heard thousands of light-years away. Kinda wild to realize we’re already making our mark on the galaxy! #Science #space #science
