Astronomy is looking up

My Favorite Web Sites - Winchester Star - 2/28/02
 by Martin Zombeck

This is a bi-weekly column providing an annotated list of Web sites that may be of interest to the community. Each column will list sites that belong to a particular category: search engines, art, online newspapers and magazines, health and medicine, history, business and economics, etc. or sites relevant to a particular season, for example, skiing or gardening. Most sites will be non-commercial. To make it easier to access the sites, each bi-weekly column will be posted on the Town of Winchester's Web site so that the sites can be accessed and bookmarked without having to be typed. Previous columns will be archived at the Winchester site, also.


Sunrise/Sunset/Twilight and Moonrise/Moonset/Phasestar gazerToday's Moon is shown on the left. Click on it and you can obtain the times of sunrise, sunset, moonrise, moonset, and the beginning and end of civil twilight, along with information on the Moon's phase for any location and date. Have you recently looked up at the night sky and wondered what that bright object is? Is it a star or planet? Do you want to know what the surface of Mars looks like? The links below will provide you with spectacular images of astronomical objects, maps of the night sky, predictions of satellite passes, information on meteor showers and comets, the "weather" in space, the exact time anywhere in the world, a list of the world's largest telescopes, authoritative information on many astronomical topics, and permit you to make your own astronomical observations with an on-line telescope. You can get the answer to an astronomical question by consulting a NASA scientist on-line.

If your favorite astronomical site is not here, e-mail the Web address (URL) and we will consider the site for inclusion in our list.
