Space imagery. You can browse NASA’s Image and Video Library online; you can also access it via NASA’s API. Through that interface, you can search by caption, keyword, location, photographer, year created, and other fields; in return, you get structured data on each media file. The library was launched two years ago, bringing together more than 140,000 images, videos, and audio files that had previously been spread across dozens of separate collections. [h/t Seth Donoughe]
Supreme Court v. Congress. The Judicial Review of Congress dataset, compiled by Princeton politics professor Keith E. Whittington, “catalogs all the cases in which the U.S. Supreme Court has substantively reviewed the constitutionality of a provision or application of a federal law.” The dataset currently covers 1,308 cases, stretching from the high court’s founding through its 2017 term. For each case, it specifies the statute being reviewed, how long the statute had been in effect, the main constitutional issues at hand, the outcome, and more. [h/t Sheldon Gilbert]
Art-world salaries. This is the spreadsheet that “broke the art world’s culture of silence.” In just a few weeks, Michelle Millar Fisher and anonymous colleagues have collected more than 2,600 self-reported salaries from their fellow curators, managers, interns, and other art-world employees. Related: “It took us three minutes to build this spreadsheet,” the organizers have written in The Art Newspaper. “It is not a perfect survey tool, nor was it ever intended to be. While we’ll work with statistics professionals to review and glean meaningful facts […] Its primary goal is to catalyse us all into action.” [h/t u/cavedave]
