Getting Landsat images to overlap

Hi there,

I am doing study on land cover change over a period of 27 years. I have one Landsat image for each year, but as the entire area is too large, I am clipping a smaller subset in each image (these subsets will have the same coordinates in each of the 27 images). Problem is, when I try to clip these subset areas, the images don't line up between years.

I tried defining each image with the same coordinate system, but I think the problem is that the original Landsat images aren't exactly lined up. Anyone have any advice? I need these layers to line up cell by cell, as eventually I would like to do cell statistics.
