About the 100th Anniversary Debate 
This 100th Anniversary debate has been organized by the same people 
who have written and edited the 
Astronomy Picture of the Day 
(APOD, main NASA site: 
https://apod.nasa.gov/) 
since 1995. 
This is NOT the first astronomy debate they have organized 
commemorating the 
1920 Great Debate between Shapley and Curtis -- there 
have been 
three others. 
All of their other debates were in the 1990s, though. 
The first of which, the 
75th Anniversary debate, occurred in 
1995 -- about two months before they created the 
first APOD. 
For those keeping score, on 2020 April 26, the count was APODs: 9078, Debates: 4. 
The organizers expect this to be the last debate that they organize,
 but when the last APOD will appear -- that they write or edit -- 
they don't yet know.
