The Chandra X-ray spacecraft may soon go dark, threatening a great deal of astronomy

Without question, the unexpected end of Chandra would be heartbreaking for astronomers, and for astronomy. Scientists who use the Earth-orbiting spacecraft as their north star to elucidate the structures of black holes will face layoffs, and there is currently no other observatory capable of achieving the kind of X-ray resolutions Chandra has been obtaining since it reached its cozy spot around our planet in 1999. It is these resolutions, in fact, that have allowed those black hole scientists to study not just the voids themselves, but also many cosmic wanderers with the misfortune of treading too close.
