Mars, brightening quickly in the constellation Cancer, lies less than a degree south of the waning gibbous Moon. Observers in parts of northern Alaska, northern Canada, and northwestern Europe can see the Moon occult the planet tonight! SOURCE: timeanddate.com

Did you know that Orion the constellation is visible to most of the world? It falls between 64°N and 75°S, and tonight the Orion Nebula is perfectly placed for viewing, right here in Wisconsin! #wherethestarshangout

Here's our festive lineup for the week! Hope to see you soon! #wherethestarshangout

Check out the full moon tonight! And, not surprisingly, one of the December full moon name is ""Cold Moon."" It is also referred to as ""Full Long Nights Moon"" #wherethestarshangout

Christmas is coming! Visit us today for a little holiday happiness and space! At 11am, we'll offer our newer show ""Let It Snow"" for our younger audiences. Later at 1:00pm, we'll feature ""Mystery of the Christmas Star,"" with a star talk.

Again tonight, if the conditions are right, you could potentially observe the Geminid meteor shower! Find a dark place to observe and enjoy! They only come around this time each year. #wherethestarshangout

The KING of meteor showers peaks tonight, the Geminids. However, please know that tonight is the peak, & the approaching full moon will interfere strongly with viewing. Though it might be cold, you may still want to get outside to take a peek.
