Chippewa Valley Astronomical Society

 

Bringing knowledge of astronomy and enjoyment of the night sky to the Chippewa Valley of west-central Wisconsin

 

Planets Around Other Stars
Nathan Miller
Department of Physics and Astronomy
UW – Eau Claire
For centuries, astronomers have dreamed about the possibility of
planets orbiting other stars, but until recently the planets which make
up our own solar system were the only planets known. Now, over
3400 planets have been discovered and more are continually being
found. This talk will focus the methods astronomers use to discover
these planets and how their properties are determined. Interesting
comparisons can be made to the planets in our own solar system. I will
conclude with a brief discussion of what these new planet discoveries
tell us about the possibility of life elsewhere in the galaxy. This talk will
help prepare you to understand the news reports that are sure to be
coming in the next few years in this exciting and rapidly-developing
area of science.

CVAS Planisphere

A planisphere is a star chart that can be set for any day or time.  It is useful for learning stars, constellations, and motions in the night sky.  A copy of the

files required to assemble the CVAS PLANISPHERE is available for download by clicking HERE
