Welcome everyone to universe evolution.well this a compulsory site one(universe lovers) has to look through.. i'll be posting some thrilling,mysterious facts about our solar system...
ARE THERE ALSO GALAXIES WHICH ARE RACING TOWARDS US?
Although the universe as a whole is expanding, there are still galaxies moving in our direction- for example the nearby "ANDROMA GALAXY" which is travelling towards us at rate of about 3000 km/sec.
To understand this apparent contradiction we have to differentiate between two phenomena: on the one other hand the motion of galaxies through space,on the other hand the expansion of the cosmos itself.Random motions of galaxies in space are typically in the order of a few hundred kilometres per sec. For galaxies that are very close to our milky way galaxy, the expansion is negligible compared to that of expansion.Hence all distant galaxies seem to be rushing away from as a result of expansion,whereas near by galaxies can be moving either towards us or away from us.
