"The Ring Nebula is one of the most well-known planetary nebulae in night skies and Hubble is able to study its structure with amazing clarity. Planetary nebulae are formed when stars, of approximately the same mass as the Sun, run out of fuel, blast ferocious stellar winds into space and die. We are looking at the death throes of a once healthy star, a fate that awaits our Sun in a few billion years time." -Dr. Ian O'Neill, scientist and #DiscoveryNews Space Producer
