You just never know what might be lurking in old data, awaiting discovery.
Or perhaps pre-discovery. As we approach the eve of New Horizon’s historic fly-by of Pluto and its moons tomorrow, we thought we’d turn your attention to a recent amazing find from the Carnegie Observatories’ archive. The collection includes more than 200,000 glass plates of the night sky going all the way back to 1892 from three separate observatories.
