- ÊOctober 28, 2002, Light Pollution Goes Mainstream, By Richard Tresch Fienberg -- If the fall 2002 meeting of the International Dark-Sky Association (IDA) proved anything, it's that astronomers have lost control of the light-pollution issue Ñ and that's a good thing. Like the spoiling of our air and water, the loss of nighttime darkness is becoming a serious concern not only to astronomers but also to health-care professionals, zoologists, lighting engineers, politicians, and the public. Some 175 activists gathered in Boston and Cambridge, Massachusetts, last Friday and Saturday for the IDA's first national meeting outside its headquarters city of Tucson, Arizona. They learned that poorly designed light fixtures do more than just blot out our view of the starry sky. They also disrupt our circadian rhythms, cause accidents on roadways, confuse migrating birds and other wildlife, and waste billions of dollars in energy costs.

Distances to Stars -- directly access the Hipparcos data base
and calculate the distance to any of the 100,000 stars it contains.
http://cdsweb.u-strasbg.fr/hipparcos.html;
Click on I/239; Select Main Catalog to arrive at the VizieR Search Page; Type the name of the star in the Target field then click Submit Query;
Scroll right to the PLX field, which is in units of mas (milli arc seconds);
Move the decimal point three places left to get seconds of arc;
Use the formula d=1/p to calculate the distance (where p is the parallax in seconds of arc, and d is the distance in parsecs, one parsec = 3.26 ly)--Example: For the star Dubhe, the query returns 26.38 mas. So the distance
is 1/.02638, or 37.9 pc. Finally, 37.9 pc is equivalent to 124 LY. You can also use a location in the target field. Example: 11:04 +61:45 The declination must have a + or - sign. If you need to pinpoint more accurately, you could use 11:04:43 +61:45:04. Colons may be dropped and replaced by spaces. VizieR doesn't seem to know all the stars. Alkaid, for example, is not found by name.

You can participate by running a screensaver program that downloads and analyzes radio telescope data. There's a small but captivating possibility that your computer will detect the faint murmur of a civilization beyond Earth.
