Tellus Museum in Cartersville presents a full day and evening of science fun this Saturday, April 20, combining National Astronomy Day with Family Science Night.

Special guests Geoff Notkin and Steve Arnold, stars of the Science Channel program “Meteorite Men,” will give a presentation at 1 p.m., and will host a screening of an episode of their show at 5 p.m.

During daylight hours, visitors can view the sun in the observatory. According to the museum, the sun has been active lately, so you can expect to see sun spots and “solar prominences.” (I’m not sure what those are, but if Tellus thought them worth mentioning, surely they must be cool.)

After sunset, the observatory will zoom in on the moon, Jupiter, the double star Algieba, or Saturn. Also, at 9 and 9:30 p.m., Tellus astronomer David Dundee will lead groups on star walks to observe the night sky.
