i have been going around collecting datacrons and have been able to get the other ones but just not these two so far

i do not have a full quest log. this is my first char and i dont remember ever having gone to get these datacrons or ever going to the area where you find them...

Can anyone tell me why there are two datacrons on dromund kass that when i click on them it keeps giving me the message "you are no longer able to access this datacron". is it possible to out level a datacron?
