  No! I look at brown and white dwarfs to find out what they are made of – I can’t do that on myself.
- Nate Bastian answered on 20 Jun 2014:
  
  No, since we’re astronomers, we look out into the universe to do our research. So, there are few experiments that we can do on earth, and none on ourselves.
- Natasha Stephen answered on 20 Jun 2014:
  
  No I haven’t tested anything on myself. As Nate and Sarah have said, it would be quite difficult as we look at things in Space.
  
  But, I do use x-rays to look at my rocks and I have had many X-rays recently as I broke my thumb – does that count?
- Roberto Trotta answered on 23 Jun 2014:
  
  No, all the stuff I work on is very far away or otherwise invisible, so there is no testing I can do on myself.
  
  But often I do demonstrations for schools and students, and they usually involve some foodstuff, cooking, explosions or a mixture of them — and I always try them out on myself first!
