I went to a meeting tonight, and then to an astronomy lecture at a local library. The speaker brought a home made telescope and set it up in the parking lot of the library. This is probably the worst place for observing the heavens that I have ever seen! There were giant bright lights on tall poles illuminating the entire lot. There was hardly a star to be seen. Someone asked "Where is Alberio?" Alberio is a gorgeous double star, one orange and one blue. When I took this, different people were pointing to where they thought it was, or shielding their eyes in order to be able to look for the star.
where is it? and can it be seen without a telescope?
ReplyDeleteYes it can, but only a telescope can show you two stars, where the unaided eye sees only one. Alberio is in the constellation Cygnus, which looks like a giant kite in the skies. Go here to Wikipedia, and then click on the map to see it in greater detail. The star Alberio is named. - http://en.wikipedia.org/wiki/Cygnus_(constellation)
