Stargazers were treated to a rare sight on Sunday night: a supermoon eclipse. The phenomenon only happens when a full lunar eclipse coincides with the moon’s closest approach to the Earth. Until Sunday night, these events had not occurred in unison for 33 years, and another 18 years will pass before we get to experience a supermoon eclipse again.
