Spring Constellations

Happy spring vernal equinox!

Near the end of last year I read about astronomy and learned some basics. Worldwide, officially there are 88 constellations—one for every key on a piano. Some are visible only in the northern hemisphere, some only in the southern hemisphere.

Within those latitudinal limits, not all of them are visible all year long. During half the year the sun blocks are view of some constellations altogether, and then half a year later blocks the other half. There are a couple lists that show which is visible when.

Northern hemisphere spring constellations include: Bootes, Cancer, Crater, Hydra, Leo, and Virgo.

Polar constellations are visible in their respective hemispheres all year long. In the northern hemisphere this includes: Cassiopeia, Cepheus, Draco, Ursa Major, and Ursa Minor.
