I saw the Christmas star on Dec. 21! Did you see it? Did you know what it was? Bear Essential gave Young Reporters the opportunity to interview Steve Kortenkamp, an astronomer at the University of Arizona.
He said that the conjunction happened because Saturn and Jupiter aligned by orbiting the sun and eventually lining up. The moon and the Earth do the same and that is called an eclipse. Some are solar eclipses while others are lunar eclipses. The next time that a nice solar eclipse will happen in Arizona will be in 2024.
