    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 Hercules, the great warrior

Hercules

Hercules, the great Greek warrior, can be seen kneeling in the sky for northern latitudes throughout the Spring months. Hercules first becomes visible in the east in April, and works his way high across the night sky through October. From the southern hemisphere, he appears low in the north. Four of Hercules' brighter stars form what is commonly known as the Keystone. Hercules' arms and legs extend from this central square.

By far the most exciting object to see in Hercules is the magnificent globular cluster M13, which is visible in dark night skies even without binoculars or a telescope. With the naked eye, this cluster of more than 300,000 stars appears as a faint fuzzy spot between the stars which form the western side of the Keystone.

Many other constellations were unfortunate victims of Hercules, and thus were also placed in the sky. According to the legends surrounding Hercules, he slew Leo, the Lion, Draco, the Dragon, and Hydra, a Serpent with nine heads, as part of his Twelve Labors. Cancer, the Crab was sent by Hera to annoy Hercules in his battles, and became yet another victim of the hero.
