    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    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/.

Rosetta Mission Page

The Rosetta Mission was suppose to launch in January 2003. Unfortunately, the launch had to be delayed! The good news is that Rosetta has a new launch date, February 26, 2004.

Rosetta will not meet up with comet Wirtanen as was originally planned. Instead, the spacecraft will fly towards comet 67P/Churyumov-Gerasimenko. (shortened as comet C-G)

After launch, Rosetta will then begin a ten year journey to the comet C-G. Rosetta will study this comet in detail, in hopes that this will lead to new scientific findings about all comets. Learning about comets helps us learn about our own solar system and about how the solar system originally formed.

The Rosetta spacecraft is actually made of two parts: an orbiter, which will approach the comet and then circle it, and a lander, which will touch down on the comet. Rosetta has many complex scientific instruments that will help us find out about this comet's nucleus, coma and tail.

The Rosetta spacecraft is named after the Rosetta stone, a famous stone that allowed us to figure out what Egyptian hieroglyphics say.

Scientists are excited about new discoveries Rosetta might help make. This is the first comet mission where part of a spacecraft will actually touch down on a comet. Watch for news to come regarding the Rosetta Mission!

Comet Churyumov-Gerasimenko

Comet 67P/Churyumov-Gerasimenko was discovered in 1969 by Klim Churyumov and Svetlana Gerasimenko. The comet orbits the Sun once every 6.57 years. Its orbit brings it closer to the Sun than Mars at the...more
