Moon

A supermoon occurs when the moon is closest to Earth along its elliptical orbit, which means it can appear larger and brighter to viewers. The last one of the year will be visible Thursday and Friday.

The Earth's lunar sidekick will appear extra big and bright as it reaches its fullest stage on Wednesday. It's not just the biggest supermoon this year, it's also a rare blue supermoon.

Two stellar lunar events are happening this August, with a sturgeon supermoon on Aug. 1 and then a rare blue supermoon on Aug. 30.

Monday's moon is a so-called supermoon because it will be both full and located close to Earth on its elliptical orbit around our planet.

In the wee hours of Tuesday morning, the moon fell completely into Earth's shadow and turned a shade of red — either an astronomical delight or Election Day omen, depending on who you ask.

South America and much of the continental United States had the best view of Sunday night's lunar eclipse, which lasted nearly five hours.

It will be the second and final eclipse of the year. West Coast night owls and East Coast early risers could catch the peak of the cosmic event.

The "Super Flower Blood Moon" is happening early Wednesday morning, as a supermoon coincides with a full lunar eclipse. Here's how to see it.

It turns out that all full moons are not created equal: Every so often the moon is full when it's at its closest point in its orbit around our planet. The last "super moon" occurred in March 2011.
