    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

    Massive Tornado Outbreak on Tornado Alley

    The week of May 19 brings dozens of tornadoes to Tornado Alley in the states of Oklahoma, Kansas, Iowa, Illinois and Missouri. On May 20th, a massive tornado struck Moore, Oklahoma, devastating communities - destroying over 100 homes and hitting two elementary schools and a hospital - with many casualties and deaths. Our thoughts are with our friends and colleagues suffering from these storms. For more on the May 20th storms, see the NOAA Storm Prediction Center Storm Report.

Pisces

The constellation Pisces is known as the fish. Almost every ancient civilization saw this figure. It is either explained as a single fish or a pair, depending on the civilization. Pisces can be found during the months of September through January.

In Greek mythology, the two fish represent Aphrodite and her son, Eros. One day they were fleeing the giant Typhon, when they jumped into a stream, turned to fish and swam away. It is said they tied a string to their tails so they could stay together. Even the constellation shows this long string shared between them.

The brightest star in Pisces is named Alrisha, which is Arabic for "The Knot". It ties the two fish together in the middle of the constellation. The easternmost fish is located just below Andromeda. The westernmost is below Pegasus. The string starts with the eastern fish and travels south towards Cetus before heading west to connect with the other fish.

Unfortunately, there aren't many objects of interest in Pisces. There is one galaxy called M74 located a little south of the eastern fish, to the left of the string.
