October 9: Trying to Prove Einstein Wrong

Caltech's Stargazing Lecture series are now held virtually on YouTube Live. These events  consist of a 30-minute science lecture, followed by 90 minutes of Q&A with an expert panel of scientists.While in-person stargazing isn't possible, viewers are given an update and visualization of astronomical targets viewable in the evening sky.  

These events are open to all and held at the level of a layperson with no science background. Children are welcome to join, although some of the material may be a little bit advanced, depending on the topic of the month.

7pm -9pm Pacific,  9pm - 11pm Central, 10pm - 12am Eastern
