I recently spent 2 days doing #astrophotography at Barcroft Station in the White Mountains of the Sierra Nevadas. It’s located at 3,800 meters (12,470 ft) above sea level, with pristine Bortle 1 skies and sub-arcsecond seeing 🔭

Excited to be making the space nerd pilgrimage: catching the midnight showing of Interstellar being re-released in IMAX 🍿🥤🚀🪐
Half the theater look like they weren’t born yet when the movie first came out but nevertheless so excited for this!

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!

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!

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)
