Hi all,

pumpkinpi asked in BR if my talk at AAS will be live streamed. That one won't be, but I'm also doing Astronomy on Tap Thursday night which will be live streamed! It's only ten minutes, but I start the roster, and will be talking about what will happen if a supernova goes off in our galaxy and its light reaches us tonight.

It's Thursday, Jan 10, at 7pm Seattle time, so you all can figure out when that is for you- https://www.youtube.com/watch?v=82OFtB4pLW8

Great presentation, great Q&A from the audience!

Despite having taught astronomy for 20 years now, I love listening to other people talk because I either learn something new or learn a new way to say something. I love your term "the end of the stellar story."

Also, before this I never made the connection as to why neutrinos from a supernova arrive before the light--that they barely interact with the matter in the star. It seems counter-intuitive, that things with matter can pass so easily, while light can't.

Did I detect a slight Canadian accent?

I had to read that three times. The first two I was like "Neutrinos move faster than light?"

Great talk. I think we all need to sign up for supernovae/neutrino alerts!

Yes!

Thanks guys! If you missed the original live stream (or want to share it), the YouTube link is here- https://www.youtube.com/watch?v=KRMMhycGnFs
