Can I apply for a joint proposal using 2 or more other observatories in addition to Spitzer?

Yes, submit a single proposal and put as many observatories (up to four, HST, CXO, NOAO and/or NRAO) as you need into the appropriate window in Spot.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
