The article boasts:

'....

The Billion Dollar ALMA Observatory Can Spot a Golf Ball from 15 Kilometers

....'

,

This array consists of 54 12 meter diameter telescopes plus 12 9 meter telescopes spread over an area 16 kilometers wide..... it better be able to see a golf ball a lot further than 15 kilometers out....

.

That wounds like something Hubble could have done....even before the optics were corrected!

.

I'm pretty certain that I could buy a telescope that could see a golf ball 15 kilometers away for a price many orders of magnitude lower than the cost of this array....

although it wouldn't come with that nifty special vehicle to move parts of the telescope around....
