Blue micromoon: How to catch this rare celestial sight

Get set for a rare blue micromoon this weekend.

It's when a blue moon that's also the most distant and smallest-looking full moon of the year rises.

The brilliant star Antares will photobomb Sunday's spectacle for a celestial three-for-one.

A blue moon occurs every two to three years when a second full moon squeezes into a single month.

May 1 saw this month's first full moon.

The upcoming full moon will be farther from Earth than usual at a distance of 252,360 miles.

That will make the moon seem a bit smaller and dimmer.
