    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 Lyra, the Harp

Lyra

Lyra, the Lyre, is a type of small harp held in the player's lap. The brightest star in Lyra, Vega, is placed in the handle of the harp. A small parallelogram of four faint stars just to the southeast of Vega outline the harp itself. Lyra is one of three constellations whose brightest stars form the Summer Triangle.

Vega is a very bright star (the fifth brightest in the whole sky) and is very close. Lyra is also home to one of the brightest, loveliest planetary nebulae, the Ring Nebula. It can be viewed with binoculars, although it's distinctive smoke-ring shape cannot.

According to Greek mythology, the lyre was invented by Hermes as a child when he strung a tortoise shell. He traded the lyre to Apollo, who then gave it to his son, Orpheus, a great poet and musician. Some Asian traditions see the bright star Vega as the Weaving-Princess star who marries a shepherd, the star Altair.

The Lyrid meteor shower happens in April each year. The meteors in the Lyrid meteor shower seem to shoot outward from the constellation Lyra.
