Everyone in Ireland is being urged by Astronomy Ireland to go outside on the evenings of July 3 and July 4 to see a "buck supermoon."

A supermoon, as defined by NASA, happens when the moon is full and at its closest point to Earth in its orbit. When this occurs, the moon ends up looking a little bit bigger and brighter than a typical full moon.

A buck moon, on the other hand, is a full moon that appears in July. According to legend, certain Native American tribes called the moon after a male deer, often known as bucks, whose antlers start to grow at this time of the year, giving the moon its name.

This week's supermoon, according to a statement from Astronomy Ireland, would be "30% brighter than at other times."
