"We have always a resource in the skies. They are constantly turning a new page to view. The wind sets the types in this blue ground, and the inquiring may always read a new truth."
- Henry David Thoreau (1817-1862)

"My heart leaps up when I behold
A rainbow in the sky."
- The Rainbow, William Wordsworth

"Night is a shadow world. The only shadows we see at night are cast by the moonlight, or by artificial light, but night itself is a shadow."
- Soul of the Sky, Diane Ackerman

Increasing Your Sky Awareness

    Tune in to the sky...Are you aware that the sky is on the air?
    Huh? Look, listen (with RealPlayer), and enjoy the online version of the following sky awareness radio programs:

    • The Weather Notebook, A Radio Show about Weather and Everyday Life from the Mount Washington Observatory (home of the world's worst weather).
    • StarDate radio--the longest-running science feature in the country--is the daily astronomy-related radio program produced by the McDonald Observatory, University of Texas.
    • Earth & Sky @World of Science includes a link to "Tonight's Sky," featuring a sky chart generated by Starry Night Deluxe.

  • Do you remember how the sky looked this morning? How does it look now? Visit the WeatherNet4 News Cam Web site to see the current skyscape in Washington, D.C. You can also access the last 12 hours of archived images, captured every 15 minutes (Netscape 4.x required).
  • Test Your Sky-Q (astronomy-related)
  • Look Up! Quiz and Sky Awareness Activities (weather-related)
  • Look Up! Plan to celebrate National Sky Awareness Week, April 23-29, 2000. Its theme is: "THE SKY - Where Meteorology and Astronomy Meet."
  • Clouds, clouds, and more clouds! And even more clouds!
  • Assuming the sky is cloud-free, approximately how many stars are visible in the night sky? Well, as you can see from a Light Pollution Map of the Washington, D.C. Area, that depends upon where you live. Fact of the matter is, in the most light-polluted areas of the region, only the 25-or-so brightest stars are visible! See what you're missing: visit your local planetarium.
  • Snowflakes - A Thematic Approach provides K-12 teachers with a flurry of ideas for using snow to deliver interesting and exciting interdisciplinary instruction perfect for the holiday season.
  • Annotated links to a variety of other sky awareness resources

End of Century/Beginning of New Millenium?

    Celebrate twice if you like, but 31 DEC 1999/01 JAN 2000 is neither the end of the 20th century/beginning of the 21st century, nor the beginning of the new millenium! The end of the 20th century and the start of the new millennium are at the same time: that moment between 31 DEC 2000 at 11:59:59 p.m. and 01 JAN 2001 at 12:00:00 Midnight.

    This is simply because we started counting years with the number ONE, so the beginning of decades, centuries, millennia, and other time units is at the beginning of a year ending with a ONE, e.g., 2001.
