Long Tail of NSF astronomy research funding. The data shown here represents 855 astronomy and astrophysics projects. The top 10% of projects received between 350,000,000 to about 830,000 dollars. The bottom 90% of projects received between about 830,000,000 to 5,000 dollars. The highest-funded projects require a sophisticated data management plan, meaning the Long Tail of research funding likely translates to a Long Tail of dark (uncurated) data.
