They might as well have just said:
There are three large telescopes in the works in different parts of the world. Here's a picture of one of them.
There's a similar full moon rising shot I've been dying to shoot in my home town, but there's no safe place to set up with a lens long enough to have the moon's size be impressive. Wide angle shots to establish location with the moon leaves the moon a tiny size in the image. Telephotos zoom in past the interesting scenery unless moved far enough away--the longer the lens the further away. My current plan is a big drone to support the lens but the location puts me closer to a highway than I'd like to fly a drone. Oh well, I can see it in my mind's eye
Welcome to the Tuesday Telescope. There is a little too much darkness in this world and not enough light—a little too much pseudoscience and not enough science. We’ll let other publications offer you a daily horoscope. At Ars Technica, we’ll take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

The most cutting-edge radio telescopes are arrays, which means hundreds or thousands of similar-looking dishes, typically spread out miles apart. The DSA-2000 will be in the Nevada desert, similar to how the VLA was built in the New Mexico desert.
Last laugh for US units of measure.
They get into the details of the active & adaptive optics, flagship science missions, engineering tradeoffs, etc. The podcast itself is also free and non commercial, so no ads or sponsors!

I'm currently cutting some 6" mirror blanks and hoping to eventually make an 18" mirror (have to cut and fuse the blank).
