Black Hole-chan is a moe anthropomorphism of the Powehi black hole, which gained global fame after the Event Horizon Telescope released the first-ever image of a black hole in April 2019. Artists on platforms like Twitter and Reddit quickly reimagined the blurry orange ring as a cute anime girl, often depicted with a halo resembling the accretion disk and a personality that is literally 'all-consuming.' The meme plays on the 'Earth-chan' trend, personifying celestial bodies as charming yet potentially dangerous characters. It is commonly used to joke about the irresistible pull of internet culture, the vastness of space, or simply the internet's ability to turn any scientific discovery into an anime waifu.
