Well after a whole day spent doing notes - stuff I really should have already done, but didn't have time due to obs lab running over and then the epic of group studies. Well I could have made time but frankly thought it would be best to wait till now so is fresh in my mind.

I have to say observational cosmology is really interesting, just after a while a little tedious - especially having to make sure what I am reading is up to date since the field is continually changing.

Well at least it gives me an excuse to post a wonderful picture:

This is the Universe in the microwave region, this is known as the Cosmic Microwave background and occurs at 2.72 K wow! This is light that has just reached us from the early universe and clearly shows that the Universe though very isotropic in its earlier stages still had slight fluctuations - the idea is these fluctuations are what caused the growth of structure that we see within our Universe - but then again that is probably wrong, as no one actually knows it is just one of various interpretations! Still it is still wonderful that the whole sky is full of this light from the early Universe, wow!
