Jacoby <sjacoby@noao.edu> This material is extracted from the National Optical Astronomy Observatories' Being an Astronomer FAQ, <URL:http://www.noao.edu/education/astfaq.html>. Astronomers are typically good at math, very analytical, logical, and capable of sound reasoning (about science, anyway). Computer literacy is a necessity. While not all astronomers are skilled computer programmers, all should be comfortable using a computer for editing files, transferring data across networks, and analyzing their astronomical data and images. Other valuable traits are patience and determination for sticking to a difficult problem or theory until you've seen it through---which can take years. The final product of scientific research is the dissemination of the knowledge gained, so don't overlook the importance of communication skills like effective public speaking at professional meetings and the ability to publish well written articles in scientific journals. Many of these skills are developed during one's education and training. In the U.S., a typical astronomer will obtain a Bachelor of Science (B.S.) degree in a physical science or mathematics, then attend graduate school for 5--7 years to obtain a Ph.D. After earning a Ph.D., it is common to take a postdoctoral position, a temporary appointment which allows an astronomer to concentrate on his or her own research for about two to three years. These days, most people take a second postdoc or even a third before they are able to land a faculty or scientific staff position. If you want to become an astronomer, a general principle is to obtain as broad and versatile an education as possible while concentrating in mathematics, physics, and computing. It is not critical that your Bachelor's degree be in astronomy. Students with a strong core of physics classes in addition to some astronomy research experience are most likely to be accepted to graduate programs in astronomy. Additional information on astronomy as a career can be obtained from the American Astronomical Society, <URL:http://www.aas.org/education/career.html>, and the Harvard-Smithsonian Center for Astrophysics (contact their Publications Department, MS-28, 60 Garden Street, Cambridge, MA 01238, USA, or call 617-495-7461, ask for the brochure "Space for Women").

with stars, then every direction you looked would eventually end on
the surface of a star, and the whole sky would be as bright as the
surface of the Sun.
Why would anyone assume this? Certainly, we have directions where we look that are dark because something that does not emit light (is not a star) is between us and the light. A close example is in our own solar system. When we look at the Sun (a star) during a solar eclipse the Moon blocks the light. When we look at the inner planets of our solar system (Mercury and Venus) as they pass between us and the Sun, do we not get the same effect, i.e. in the direction of the planet we see no light from the Sun? Those planets simply look like dark spots on the Sun.
Olbers' paradox seems to assume that only stars exist in the universe, but what about the planets? Aren't there more planets than stars, thus more obstructions to light than sources of light?
What may be more interesting is why can we see certain stars seemingly continuously. Are there no planets or other obstructions between them and us? Or is the twinkle in stars just caused by the movement of obstructions across the path of light between the stars and us? I was always told the twinkle defines a star while the steady light reflected by our planets defines a planet. Is that because the planets of our solar system don't have the obstructions between Earth and them to cause a twinkle effect?
