Who remembers the "eye-popping" Hubble images of V838 Monocerotis, March this year?
In the news release the phenomenon is explained as light hitting earlier expelled concentric shells of matter, see http://www.space.com/scienceastronomy/aas2...est_030526.html
What I don't understand is what concentric shells they are talking about. To my eyes there is only one shell of material that is seen expanding, you can even trace back all the structure from the last image to the first. So what is all this talk of light reflection about when clearly there is one shell rapidly expanding??
