Here's why:
* Halos are optical phenomena caused by the refraction and reflection of light through ice crystals in the atmosphere.
* The shape of the ice crystals creates a ring of light around the sun or moon, sometimes with a reddish hue.
* The "stars" are not actual stars, but the points of light where the halo intersects with the moon's light.
It's important to note that:
* Halos are common and usually don't have any specific meaning.
* They're a natural weather phenomenon, not a sign of anything supernatural.
* You might see different numbers of "stars" depending on the size and shape of the halo.
So, the next time you see "seven stars around the moon," you're likely looking at a beautiful halo!
