Learn about the night sky with these past recordings of free, live, virtual astronomy observing sessions across the state of Tennessee!
Most of these past, live sessions were hosted by Dyer Observatory at Vanderbilt. Many telescopes/astronomers, both professional and amateur across the state of Tennessee from Kingsport to Memphis, were highlighted to show off the night sky. Occasionally, there is an event hosted by Warner Park. These events are fun for the whole family.

These are the organizations that have participated in these events (in alphabetical order):
Bays Mountain Park & Planetarium
BSAS – Barnard-Seyfert Astronomical Society of Nashville
McGill University – Physics Department
Vanderbilt University Community Relations
Regardless of the local weather, each site will be prepared with a cloudy weather alternative to share. The event should last about two hours. Questions can be submitted live via the YouTube link.
Public Observing Programs – Cancelled Until Further Notice
Our observing programs are free for everyone!
Quick View:

Observatory Details – Cancelled Until Further Notice
Bays Mountain Park is home to two observatory structures housing a number of telescopes that include lensed refractors of 6″ & 8″, mirrored reflectors of 10″, 12.5″ & 17.5″, and more!
The Bays Mountain Astronomy Club and planetarium staff use all of these telescopes at various times through the year to show the public astronomical sights in nighttime skies.
Bays Mountain Park Clear Sky Chart
Click Here to go to the Clear Sky Chart’s website to learn how to correctly read the data. Clicking on the chart in their website brings up detailed information.
Quick View: you want dark blue for the first four rows.
Dark blue means no cloud cover, very transparent (no haze), excellent seeing (steady skies with no turbulence), and fully dark. For the next two rows, dark blue means no wind and very low humidity. The last row is temperature. Dark blue is super cold (-40°F – -31°F), white is at freezing (23°F – 32°F), and bright orange is moderate (68°F – 77°F).
