December 21, 4:00 – 5:00PM

A live-stream celebration with astronomy educator Bobby Farlice-Rubio!

This evening, Winter Solstice, the two largest planets in the Solar System — Jupiter and Saturn — will look closer together than they have since 1623.  Once every twenty years, these giant planets come together in our view from the planet that we share, Earth. This event is called a Great Conjunction! They will appear to be nearly touching to our eyes, although Jupiter and Saturn will still be hundreds of millions miles apart from us and each other. Telescope users will be able to see both planets in the same field of view at the same time. The next close Great Conjunction like this will not occur until 2080!

Support the Museum TODAY to save $25 on your Family Membership. For a limited time, you and your family can join for $50 instead of $75 for a full year membership. Already a member? Your support this week will go twice as far, as it is matched with an end-of-year challenge.

Click the “Support” button below and select $50 to join at the Family Membership level through this limited Great Conjunction offer.

If clouds get in the way of our view, we’ll view the Great Conjunction in real time via live-stream video from around observatories around the world.
Join Fairbanks Museum Science Educator Bobby Farlice-Rubio as he guides us through the cosmos! You can send questions to Bobby before and during the livestream, and he will attempt to answer them during the presentation. Follow along live in your own backyard, as you can bring our livestream anywhere where you can take a phone or tablet. Watch, Wonder, and Welcome in the Winter with us and this spectacular planetary encounter!
This all-ages event is free and open to the public. Just tune in to join us! All you need is to bundle up and step outside, and use your eyes to look up at the night sky. The more open your view, the better, especially to the south. If you have binoculars or a telescope, they will also help you pick out objects in the night sky, but if not, tuning into our live stream will give you an up-close look through our 10-inch telescope.
Zoom link for the live stream HERE. (password is 1302)
(Zoom is the most interactive way to participate, but we have a limit on participant numbers. You can also access the live stream on our Youtube channel HERE.)

Explore Saturn in depth.
Explore Jupiter in depth.
Prepare some questions, and send them to us!
What are Saturn’s rings made of? Could there be life on any of Jupiter’s moons? Send us your burning questions about space, the solar system, and the two gas giants that are in the spotlight for the Great Conjunction. Email your questions in advance to Or, tune in and you can ask your questions “live” in the comments section of the live stream.
