Saved you a click: it’s from a human made craft, roughly 40x Earth-moon distances away.<p>They expect to reach bandwidths 10-100x what is currently possible with radio waves. However, it requires very precise alignment, and more importantly, requires taking into account the relative movement of the sender and receiver.<p>This craft is headed further away up to where they expect the communication delay to be around 20 minutes, up from the current 50 seconds.
