In my last article I showcased a list of new and interesting telescopes that seek to revolutionize our knowledge of space and the universe.

As it happens, the launching of these innovative star-gazing devices coincides with the International Year of Astronomy, a year-long celebration of the science.

The United Nations dubbed 2009 the IYA because it marks the 400th anniversary of Galileo Galilei's first astronomical observations with a telescope and the publication of Johannes Kepler's Astronomia nova.

The Universe, Yours to Discover

That's the slogan of the IYA, which in some ways seeks to rekindle humankind's wonderment of our boundless sky. However, it also hopes to show people that scientific knowledge can contribute to peace.

More than 90 countries worldwide are already involved in providing local, regional and national events. It's refreshing to see individuals from different countries and continents come together to enjoy a pastime that dates back to 134 B.C.

Space, the Universal Language

Being curious about space is one of the purest, most universal interests in the world. At some point everyone has stared at the night sky in awe, a tiny being swallowed by the enormous behemoth that is space.

One of the biggest events of the IYA is the "100 Hours of Astronomy," which will take place from April 2-5.

This cornerstone project will consist of people from across the globe looking through telescopes just like Galileo did 400 years ago.

Technological advancements have permitted us to see celestial bodies clearer and closer than ever before. But the naked eye has consistently gazed upon stars that are light years away.

If you've ever been even just a little bit curious about all that encompasses "out there," you owe it to yourself to visit a local astronomy club or adopt a favorite constellation or star.

The IYA is the perfect time to spend either just an afternoon or an entire year learning more about the universe and your connection to it.

Did You Know?

  • If you look up into the night sky at all the stars, you will only see about .0001 percent of all the stars in just our galaxy, the Milky Way. That is about 5,000 stars.
  • The Milky Way is just one of more than a hundred billion galaxies that can be seen using modern telescopes.
  • The nearest star to Earth, other than the sun, is Proxima Centauri (or Alpha Centauri C). This star is four light years away. Our fastest spaceship would take 10,000 years to reach it.
  • The largest star, VY Canis Majoris, is over 5,000 light years away. Its volume is a billion times that of our sun, and it would take over 650,000 years to walk a full circle on its surface.
  • The next lunar eclipse will be on Dec. 21, 2010, but the longest solar eclipse of the 21st century will take place on July 22, 2009.
  • Polaris is the current north star but the brightest star in the night sky is actually Sirius.
