May 31 - Blue Moon!

Blue Moon - Once in a Blue Moon ... is a common way of saying not very often, but what exactly is a Blue Moon? According to the popular definition, it is the second Full Moon to occur in a single calendar month. The average interval between Full Moons is about 29.5 days, while the length of an average month is roughly 30.5 days. This makes it very unlikely that any given month will contain two Full Moons, though it does sometimes happen. On average, there will be 41 months that have two Full Moons in every century, so you could say that once in a Blue Moon actually means once every two-and-a-half years. So this evening you will witness a real Blue Moon!

Eagle Fall - During courtship, the male and female bald eagle lock talons hundreds of feet in the air and freefall in a series of somersaults.

May 15 - Denebola

Denebola - the second brightest star in the constellation Leo. Its name is shortened from Deneb Alased, from the Arabic phrase ذنب الاسد ðanab al-asad "tail of the lion", as it represents the lion's tail. Denebola is an A-type star, with a surface temperature of about 8500 K. It is about 36 light years distant from earth, and has a luminosity about twelve times that of the sun. Its apparent magnitude is 2.14.

May 8 - Midnight Sun

Midnight Sun - a phenomenon occurring in latitudes north of the Arctic Circle and south of the Antarctic Circle where the sun is visible at the local midnight. Given fair weather conditions, the sun is visible for a continuous 24 hours. Since there are no permanent human settlements south of the Antarctic Circle, the countries and territories whose population experiences it are limited to the ones crossed by the Arctic Circle, i.e. Alaska, Canada, Greenland, Norway, Sweden, Finland, Russia and extremities of Iceland. A quarter of Finland's territory lies north of the Arctic Circle, and as a consequence the midnight sun can be experienced — for more and more days, the further north one goes. At Finland's northernmost point, the sun does not set for 73 days during summer. In Svalbard, Norway, the northernmost inhabited region of Europe, there is no sunset from approximately April 19th to August 23rd. The extreme sites are the poles where the sun can be visible for a continuous half year.

May 2 - Flower Moon

Flower Moon - In most areas, flowers are abundant everywhere during this time. Thus, the name of this Full Moon. Other names include the Planting Moon, or the Milk Moon.

Aphid Generation - Sometimes mother aphids carry embryos that are carrying their own embryos. They give birth to "live" young who in turn are already carrying the forming embryos of the next generation. This telescoping reproduction strategy results in quick population growth.
