The 25m Dwingeloo radio telescope (owned by ASTRON) has been operating since '50s. Recently, it has been used more by amateurs and pro-am radio astronomers.

Excitingly, they picked up the Voyager 1 signal.

Voyager 1 is ~25 billion km away! (~4 x Pluto distance)

Why this is neat?

Well, the Voyagers are so far away (human's furthest objects) that we need the biggest telescopes in the world (the Deep Space Network) to normally communicate with them. Those are big 70m dishes, so much larger gain.

A 25m dish, and the work of amateurs is a really nice story!

And to give you a scale of the signal power .... the signal from your home wi-fi is billions of times stronger (I think ~10 billion IIRC) than the signal Earth receives from Voyager spacecrafts. It's incredibly feeble, so detecting it is a big feat!

Well done to this team!
