In case you haven't heard, from now until April 18, early risers anywhere in the world will get to see an unusual cluster of three planets: Mercury, Venus, & Saturn. Please note: We know that Neptune is labeled in the picture. However, you cannot see Neptune with just you eyes.

Tomorrow night is April's full moon! It is most commonly known as the Pink Moon. Northern Native Americans gave it that name. But this full moon may also be known as the Sprouting Grass Moon, Growing Moon, Egg Moon or Fish Moon. Which 1 do you prefer?

Full moon tonight
Calling all early birds! If you want to catch the view of a planet this month...Venus is easier to spot due to its brilliance, particularly if you have a clear eastern horizon. Look for it about 30 minutes before sunrise for best viewing! #wherethestarshangout
