1. Andrea Dupree:

   All stars are losing material to the interstellar medium, and we don't know how this material is lost, we know that other hotter luminous stars lose material and it quickly turns to dust making the star appear much fainter. But in over a century-and-a-half, this has not happened to Betelgeuse. It's very unique.
