Aricebo radio observatory to be decommisioned
it looks as if old age and corrosion have caught up with Aricebo, and the structure has deteriorated to the point where there's no safe way to repair it.

Yeah - it's HOW old?Dave wrote: ↑Thu Nov 19, 2020 6:33 pm it looks as if old age and corrosion have caught up with Aricebo, and the structure has deteriorated to the point where there's no safe way to repair it.

57. No wonder it has developed tendinitis and fallen arches.

It's a shame. That thing was amazing. They don't mention any plans to build a new one.

I doubt that they will replace it with anything directly similar.
Technology and technique has moved on. These days, the preferred approach seems to be to build networks and arrays of smaller radio-telescopes, and use them to "synthesize" the equivalent of a single much larger dish. That's how they created those amazing images of the accretion disk around a black hole - the network of time-synchronized dishes and receivers gave them the same angular resolution as a single dish thousands of miles across.

Well, it's younger than either of my younger brothers.
{Not by a LOT in Jim's case - he turned sixty-one earlier this year...}

And I keep wondering if anyone's tried that systematically with *optical* telescopes.

That's a good point. Believe I also read somewhere in the past few months that the U.S. is de facto abandoning its traditional lead in big-investment astronomy.Dave wrote: ↑Thu Nov 19, 2020 9:16 pmI doubt that they will replace it with anything directly similar.
