A FEW ABCs
SCALE OF THE COSMOS
SKY-FUN / SKY-GAMES
1.6.x & 1.4.1 LINKS
If you have CELESTIA 1.6.x (that is, 1.6.0 or 1.6.1 etc.) or 1.4.1 correctly installed and running in an open window, you're in for a definite treat! This website's links labeled either "1.6.x" and "1.4.1" will display their cosmic events and destinations in your open CELESTIA window! Just click on the link for the CELESTIA version that you have running and open on your computer. One click and . . . YOU'RE THERE! For example: here's a 1997 triple simultaneous solar eclipse on Jupiter (1.6.x) (1.4.1)
As above, "1.6.x" and "1.4.1" links always follow a short description of what they will display when you click on them. Running the link not only displays the described cosmic wonder, it also allows you to examine CELESTIA's settings that created it. This will help you learn to create your own views of awesome events in CELESTIA!
Be patient; links may take a second or two to load. You will find pairs of links like this throughout this website, and you may run them as often as you like. So feel free to show them to all of your friends!
Prepare to be taken all over our incredible Solar System, and far, far beyond!
UPDATE: As of January 2013, all new CELESTIA links will only be "1.6.x" links, as few if any persons are still using the old version 1.4.1 of CELESTIA.
CELESTIA'S DISPLAY OF TIME: UTC
You don't have to look far to find that a surprising number of time standards exist. Most of the world's timekeeping is reckoned in Universal Time (UT), a standard based on the Earth's rotation. Essentially the same as Greenwich Mean Time (GMT), this is adequate for most daily activities. Still, because the Earth's rotation is not perfectly constant, UT is not accurate enough for astronomical timekeeping.
On the other hand, the highly regular behavior of certain atoms provides a superior basis for measuring time with high accuracy. Coordinated Universal Time (UTC), based on atomic time, is just one of several standards used by astronomers. It is adjusted to essentially stay "in step" with Universal Time, and is what CELESTIA's clock displays in the upper right corner of its window. Universal Time and Coordinated Universal Time differ by less than a second, so for most purposes the two can be considered equal.
Note: if CELESTIA's clock is not displayed in the top-right corner of its window, just press the V key until you see it. Generally, it is best to run CELESTIA with its clock displayed, as it tells you how fast time is passing during any simulation.
"SAFARI" USERS . . .
SAFARI versions older than 5.0.5 may incorrectly read the SkyMarvels's main menu and other graphics unless you view them in Actual Size. It is recommended that you upgrade to a newer version. If you have not upgraded, the SkyMarvels™ site can be successfully navigated as follows.
In "SAFARI's" View drop-down menu:
1. select Actual Size (its text is grey when it is selected),
2. if Zoom Text Only isn't check-marked, check-mark it.
With these settings, you'll be able to enjoy SkyMarvels™ to the fullest.
