“I kinda wonder why Arecibo hasn’t been replaced by giant phased arrays in some remote locations.”
it is called SMT in Hawaii.
The Chinese built a brand new “Arecibo” in China so why copy it? They write papers just like every one else.
Astronomy covers a wide spectrum of energy, to study an object of interest.
It often takes several Observatories, all with vastly different capabilities to make a discovery.
A team effort if you will.
Time will tell.
I still would rather cure most cancers than
read papers about 13 billion year old stars,
that we only just discovered.
The stars are probably long gone by now.
In perspective the Photons warming your body, took 8 minutes or so to get here from our Suns surface.
Those Photons are probably about a million years old, they started as Gamma rays in the Fusion reactions deep inside the sun.
Think about that a bit.

spinning up. my bad. yes, perhaps shrinking. Which could be gravitational consolidation, I guess...
