FYI! Earth will pass between the Sun & Neptune. This marks the closest distance between these2 objects. With clear skies, Neptune will appear as a tiny speck in the sky. Even at its closest, Neptune is still 2.7 billion miles away. In comparison, Mars is 140 million miles away.😲

The dome is looking pretty good, right?! But, unfortunately, we're missing seats. We got word that our newly upholstered seats won't be here in time for Apple Harvest Festival. We are bummed! BUT, we are happy that they will be providing chairs to use for the next week or so.

Don't forget! We will see a partial lunar eclipse tonight! Keep your eyes on the skies between 9:12pm-10:15pm. It will be a subtle eclipse, but still cool to see! The Full Moon will be about 7% bigger than the average full moon! Feel free to share some pics, if you snag any!

Full Moon
Happy Friday the 13th! People are superstitious about Friday the 13th & Full Moons. How often do the happen on the same night? The last Friday the 13th full moon was in Oct. 2000 & it won't happen again until Aug. 2049. On average, they coincide about once every 20 years!

Saturn, the 6th planet of our solar system, will be at its brightest tonight as it rises while the sun sets. It will be visible without the help of optical aids, but you’ll need a telescope to see its rings. Telescope viewers may also catch some of Saturn’s 83 orbiting moons.
