There is no information in it, it looks like a continuous wave of radio energy coming from space. It is on a frequency that might be a natural one for any intelligent civilization to consider broadcasting on, and it is a narrowband signal, meaning it only covers a small range of frequencies.
It's a pretty easy signal to generate, even back then. I believe they've made efforts to scan the stars in that direction, but given the distance to them it would be decades or centuries until they'd see a response from us.
