What is a Planetarium Program?
A
planetarium is
a theatre built for presenting educational and entertaining shows about astronomy and the night sky. A classic planetarium accurately reproduces
the night sky on a domed ceiling allowing the audience to see the sky from any place on Earth at any time. This was accomplished with
a special projector and was controlled normally with an panel of dials and levers that would impress an airline pilot.
A planetarium can show an audience the night sky from any location on Earth. It can speed up time to show the motion of sky through the night, show the
moon and planets, highlight the constellations, and show a myriad of other objects. A planetarium program does this on your desktop computer or smartphone.
Why Stellarium?
There are quite a few planetarium programs available, but a very good one is Stellarium and it's a free application funded by donations. For desktop computers, it's available on Windows, Mac OS, and Linux. For smartphones, they have versions for Android and iOS. But almost all of the other programs have the same capabilities as Stellarium so don't think you have to get that particular program. One of the advanced functions of many of these programs is they can control a telescope, but this will depend on having a compatible GoTo telescope mount. A planetarium program is great for both beginners and experts, but we will concentrate on how it can help those starting out in astronomy.
Viewing the Sky / Learning the constellations
Note: this is not a "how to" guide on using Stellarium! We are simply showing some of it's capabilities, especially for those who are relatively new to astronomy.
When you open Stellarium by default it is going to show you the sky looking South from the default location at the current date and time.
You'll want to change that
location to one that's in the Stellarium directory that's relatively close to your actual location. (There is an extensive User's Guide that you can
download from their website.) From there you can change the direction of your view, zoom in, zoom out, and modify the date and time.
What follows are various views of the winter sky looking directly south to show you the display possibilities.
Sky with no labeling.
Sky with the brightest stars labeled.
Sky with the constellation lines.
Sky with constellation lines and constellation labels.
Sky with the brightest stars, constellation lines, and constellation labels.
Sky with the brightest stars, constellation lines, constellation labels, and constellation art.
Alternate Constellation Lines
Another feature of Stellium is the use of alternate constellation lines. One change you might consider if you like the HA Rey constellation lines is to instruct the program to utilize them. They are used in the the above screen shot.
The 88 Constellations
Throughout the entire sky we recognize 88 constellations. But from a location such as Milwaukee you can only see about 60 of them. To see the ones hidden you need to travel south, the farther south the better.

For a much greater understanding of the consellations, we have a whole section on our website dedicated to the topic called Stargazing. It contains a wealth of information for both beginners and those with more advanced knowledge. Click/tap here to go to that section.
Locating the Planets
A very great use of the program, especially for beginners, is seeing the location of the planets. The planets are always in motion so their position changes even on a daily basis.
Learning about the Celestial Sphere
Another great thing about a planetarium program is facilitating the learning of the celestial sphere. This topic is so important we will devote a whole web page to it. Click/tap here to go there.
