Now they're building the ELT –– Extremely Large Telescope. They're great with names haha.
Don't forget OWL: Overwhelmingly Large Telescope ( https://en.wikipedia.org/wiki/Overwhelmingly_Large_Telescope ).
Or, "Once Was Larger"
"The ESO specialists expect resolutions from OWL that are up to 40 times higher than those of the Hubble Space Telescope. If the 100-meter mirror cannot be financed, a 60-meter variant is being planned. The name OWL would remain the same. Because then the project is jokingly called »Once was larger«."

Still waiting for the Stupendously Gigantic Telescope.

#14What does it mean for an AGN to "turn on"?
It ate a star.

It confused me too. At first I thought it meant that a collection of matter became dense enough to form an event horizon and become a black hole. Instead, from https://www.livescience.com/space/black-holes/gargantuan-bla...
> If J221951 is indeed a supermassive black hole, its sudden burst of brightness has two possible explanations, according to the researchers. First, the black hole could have pulled an orbiting star into its clutches, stretching and tearing the star to shreds in a messy process called a tidal disruption event or "spaghettification." The second, more mysterious possibility is that the black hole could have shifted states from dormant to actively feeding, as it suddenly began gorging on the fast-moving disk of gas that surrounds it.

But that would take infinite time (as we perceive the event) because of time dilation. You would not see it "turn on", you would see a slowly, very slowly, changing signal.
I think this is good evidence in favor the plasmoid model from Eric Lerner as a replacement for black holes. Some key differences.
* Instead of a black hole eating a star, a plasmoid is having an increased load. * Black holes are "gravitational" machines while plasmoid are "electromagnetic" machines. * With the plasmoid model there is no time dilation * With the plasmoid model, the load is any source of plasma, not necessarily a star
