    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.

The constellation, Pegasus. To see the Winged Horse, you must imagine the constellation in the image flipped over.

Pegasus

The constellation Pegasus represents the white, winged horse of Greek mythology. This beautiful figure can be seen high in the sky starting near the end of summer and continuing through autumn if you live in the Northern Hemisphere. If you are below the Equator, look for Pegasus in late winter and through spring. When looking at the image, it is difficult to see the figure as a horse. That is because the constellation is actually upside-down! Imagine it flipped over, and you can see what could be the neck and head of a horse and two legs sticking out from the famous "Square of Pegasus".

This square represents the front half of the horse's body. Mythologists are still not sure what happen to the other half of the constellation. The square is very easy to find in the night sky. The neck and legs of the horse shine brightly on clear nights.

The story behind Pegasus begins with the battle between Perseus and Medusa. When Perseus severed Medusa's head, drops of blood fell into the sea. They mixed with sea foam, and Pegasus was born. The white sea foam gave the horse his brilliant color. Pegasus became friends with the warrior, Bellerophon. One day, Bellerophon tried to ride Pegasus to Mount Olympus. This angered Zeus so much that he sent a gadfly to bite Pegasus. When the horse was stung, Bellerophon fell to the Earth. Pegasus made it to the home of the gods, where he still remains.

Pegasus is home to several galaxies and even a bright globular cluster.
