Bask in the glow (or shadow as the case may be) of the supermassive black hole in the M87 galaxy, named Pōwehi, with an adjustable ring featuring its image. The ornate, gothic style complements the cutting-edge technology of the Event Horizon Telescope, a world-wide network of radio telescopes, used to create the image.
Ring is made of oxidized brass with an 0.4-inch image under glass. Ring width is 0.7 inches adjustable smaller or larger. Avoid getting this piece wet in order to preserve the image.
