In April 2012, the brilliant planet Venus will shine at its brightest for the year and the Lyrid meteor shower will light up the night sky. But these are just a couple of the must-see skywatching events in the weeks ahead. Take a look at April's best skywatching events below and happy stargazing!
Fri., April 6, 3:19 p.m. EDT
The Full Moon of April is usually called the Egg Moon. In Algonquian it is called Pink Moon. Other names are Sprouting Grass Moon, Fish Moon, Seed Moon, and Waking Moon. In Hindi it is known as Hanuman Jayanti. The Full Moon rises around sunset and sets around sunrise, the only night in the month when the Moon is in the sky all night long. The rest of the month, the Moon spends at least some time in the daytime sky.
