Abell 21 and Sharpless 2-274 (Medusa Nebula) Wall Art including Frame t-shirt The brightest stars in theESOs Very Large Telescope in Chile has captured the most detailed image ever taken of the Medusa Nebula (also known Abell 21 and Sharpless 2 274). As the star at the heart of this nebula made its final transition into retirement, it shed its outer layers into space, forming this colourful cloud.
