Nothing could travel so fast that you see it after it hits you, according to current theories, as nothing can travel as fast as light: even if it was getting say 0.5 ly closer every year, and emitting one unit luminance per year, we would still see all of the photons from the new place as well as the old one... but yeh, the dopler shift for light gives us redshift and blueshift: combining this with our knowledge of the type of atoms out there, looking for instance for the H-alpha emmision line which without a shift has a waveleanth of 656.28 nm wherever the hydrogen is. By comparing this emis

I would send it to the heliosphere, or close in... maybe a sun-mercuary lagrange point? the amount we dont know about the suns daily processes amazes me, and it is bound to have some very interesting results, and amazing photographs too.

Hello! Just joined, thought i would introduce myself: got into astronomy via my phone (google sky maps ) and after an enjoyable summer having an odd glance up, I started my physics degree and have had a great term, with the basic astronomical terms explained too... on a couple of clear nights recently, I played around with the optics i had in the house (a pair of 35mm, variable zoom binoculars being the best) and have enjoyed seeing a whole lot more stars than i normally do, even if I have been rather focused on orion. Im looking forward to learning more and seeing more amazing sights from t
