Distance: How do we know how far?

When 4/13/2019 8:00 PM - 10:00 PM
Where Sugar Grove Nature Center
Description We look at how we estimate distances in astronomy.

In addition, we will have a laser-guided sky tour and telescope observing.

Cloud cover prevented observing, but we had a good turnout.
Sunil (ISU prof) gave a very nice presentation about the history of determining distances.
