Rare blue supermoon to light up Monday night sky, leaving stargazers over the moon

The moon will look largest at dusk, one expert says, and those with binoculars should be able to see Saturn’s rings too

The world will see a rare blue supermoon this week, with stargazers getting a glimpse on Monday night into Tuesday morning.

The moon will appear about a seventh bigger and brighter on Monday evening as a blue moon and super moon coincide.
