This month's newsletter highlights several timely resources and new content on the Windows to the Universe website, as well as our professional development activities planned for the upcoming National Science Teachers Association meeting this coming March in Boston. We also highlight several resources and opportunities provided by Partner organizations and programs, including the National Earth Science Teachers Association, NCAR Online Education, and the International Polar Year.
February is special for us here at Windows to the Universe since it marks the anniversary of the project. Windows to the Universe started in February, 1995, with funding from NASA. Since that time, we have continued to develop content and resources for teachers, students, and the public, as well as developed a professional development program for teachers with the support of NASA, the National Science Foundation, and collaboration with numerous university partners and projects. Thanks to everyone that has made it possible for us to support Earth and space science education and literacy over the past 13 years, now reaching over 21 million users per year annually.
The calendar used in most parts of the world today has 365 days in most years. However, it takes the Earth 365.2425 days to make one trip around the Sun. How is this extra quarter of a day taken into account? Approximately every four years in the Gregorian calendar, February has 29 days instead of the usual 28 days. This type of year is called a leap year. Have your students do some math to figure out which years have that extra day. The instructions are on the leap year page.
Celebrations are an important part of every culture. They provide common bonds allowing people to share a meaningful connection to one another. The word ‘February’ derives from the Latin februum, which means “cleansing or purification”, reflecting the rituals undertaken by the Romans before spring. Having only 28 days in non-leap years, February is also known in Welsh as ‘y mis bach', which means ‘little month’. There are many celebrations during February which are related to the Sun and Moon .
February 3, Carnival Sunday, to February 10, Piñata Sunday: The word Carnival originates from Latin carn-, caro, carne- flesh + levare to remove, the word literally means, removal of meat. Carnival is celebrated in preparing for the Lenten season. It is the predecessor of the Mardi Gras and Fat or Shrove Tuesday. The ancient Egyptians were the first recorded culture that celebrated Carnival, setting aside five of the 365 days of the year to restore harmony to their relationship with the gods of the universe by the custom of aligning the occurrence of Easter Sunday and then Mardi Gras annually with the Sun, Spring full moon and the rhythms of the magic number seven.
February 9, Chinese New Year: The Chinese calendar is based on a combination of lunar and solar cycles. The lunar cycle is about 29.5 days. In order to "catch up" with the solar calendar the Chinese insert an extra month once every few years (seven years out of a 19-year cycle). This is the same as adding an extra day on leap year. According to the solar calendar, the Chinese New Year falls on a different date each year. Each year begins with the New Moon and ends on the full moon 15 days later.
February 20-21, Full moon eclipse! From start to finish, this lunar eclipse will last for about three hours and twenty-six minutes, not including the penumbral phases. The entire lunar eclipse will be visible from South America and most of North America, as well as from Western Europe, Africa, and western Asia.
We have a new portal to some great resources from the National Science Foundation (NSF)! Check out some of the best materials from NSF, including podcasts, video clips, interactive features, and news stories. These projects span many different science topics and provide a fun way to engage in science learning. We will be adding more items in each of the categories regularly, so please check back again soon to see what is available! Recent additions include a new podcast on the speed of human evolution and news about what earthquakes under the Pacific Ocean reveal about the circulation of the water in hydrothermal vents.
"The Earth's climate is now clearly out of balance and is warming," according to the statement about the human impacts on climate released by the American Geophysical Union on January 24, 2008. The American Geophysical Union (AGU) is a scientific organization with over 50,000 members that is dedicated to improving our understanding of the Earth and space for the betterment of humanity. Their new statement is an update of the organization's 2003 statement to reflect current understanding of the science of climate as well as the extent to which we humans can better the situation. The statement goes on to say that temperatures of the atmosphere, land, and oceans, the extent of sea ice and mountain glaciers, sea level, and other aspects of the Earth system, "are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century."
For more information about the science of Earth's climate system, visit the Climate and Global Change section of Windows to the Universe. There you will find content about the science of climate, the impact of climate change on the Earth system, paleoclimates, climate modeling, and short summaries of the reports issued by the Intergovernmental Panel on Climate Change in 2007. Peruse our suite of classroom activities that allow students to explore aspects of climate science in a hands-on way. If you are interested in furthering your own understanding of this rapidly advancing science and how to incorporate the science in your middle or high school classroom, consider taking a Climate Discovery online course for educators.

Upcoming Polar-Palooza events are available here, including a student and teacher workshop and presentations at National Geographic Headquarters (Grosvenor Auditorium) in Washington DC on March 13-14, 2008. Check out the news on this site as well, including a report on the speed up of Antarctic ice loss, the new real color map of the Antarctic, and changes observed in the circulation of the Arctic Ocean.
A spectacular collection of images documenting the Inuit experience at the turn of the last century is available on Windows to the Universe. Check out these evocative images from the Library of Congress, and links to related content on the website.
Cosmic rays are a type of radiation that comes from space. They aren't really "rays" at all, but a type of particle radiation. There are several different types (and corresponding sources) of cosmic rays: solar cosmic rays, galactic and extragalactic cosmic rays, and anomalous cosmic rays. Earth's magnetic field and atmosphere shield us from most of this high-energy radiation, though astronauts in space and satellites aren't so lucky. Future missions to the Moon and Mars will need to take special precautions to protect crews and equipment from cosmic rays. Surprisingly, the greatest threat from cosmic rays is not at the time when the Sun is at the most active phase of its 11-year solar cycle. Radiocarbon dating using carbon-14, with its many applications to archeology and other fields that delve into our past, would not be possible if there were no cosmic rays. Want to know more?

Project BudBurst will officially get underway for the 2008 campaign on February 15, 2008. Project BudBurst is a national field campaign for citizen scientists designed to engage the public in the collection of important climate change data based on the timing of leafing and flowering of trees and flowers. Last year's inaugural event drew thousands of people of all ages taking careful observations of the phenological events such as the first bud burst, first leafing, first flower, and seed or fruit dispersal of a diversity of tree and flower species, including weeds and ornamentals. Your help in making observations and sharing information about Project BudBurst will help us in making this year even more successful.
We are excited to announce new features added to the Website that will greatly expand the usability and enhance your experience while participating in Project BudBurst!
• Expanded time to participate! Staring February 15th and continuing until the fall.
• A myBudBurst member registration space! This allows you to save your observation sites and plants online as you monitor phenological changes throughout the year and for future years.
• More plant species! We have expanded the targeted species list based on your feedback. We have also included the 19 ‘calibration' species from the National Phenology Network.
• Feature of the Month! Each month our Website will share pictures of the latest plants blooming.
• An online geolocator! This gives you an easy way to obtain latitude and longitude coordinates for your observation sites

A number of teachers this winter (summer in the southern hemisphere) are working on research projects in Antarctica. Other teachers, students and the public can participate virtually through these teachers' blogs and through live webinars. PolarTREC is an educational research experience, funded by the U.S. National Science Foundation and managed by the Arctic Research Consortium of the U.S., in which K-12 teachers participate in polar research, working closely with scientists as a pathway to improving science education.
In celebration of the International Polar Year (2007-2009), a global
scientific campaign to advance our understanding of the Polar Regions,
thirty-six U.S. teachers will spend two to six weeks working with a
research team in the Arctic or Antarctic, exploring the environments,
cultures, history, and science. PolarTREC teachers will learn about
cutting-edge scientific research on topics ranging from atmospheric
chemistry to seabird ecology and will share their experiences with
scientists, educators, communities, and hundreds of students of all ages
across the globe.
