According to The Washington Post:

In a briefing at the Goddard Space Flight Center, scientists said that observations by the telescope have resulted in an average of 12 published discoveries a week for years, and that almost 4,400 principal and co-investigators have produced articles based on its data.

"This is surely the most productive telescope in history," said Charles Mattias "Matt" Mountain, director of the Space Telescope Science Institute on the Johns Hopkins University campus in Baltimore.
