Looking Back in Time


This is a picture of the Galaxy M81.
~
Who knows what it really looks like, because this is what it looked like millenniums ago, since the light just hit the Hubble telescope from 11.6 million light-years away.
~
Everything that we see is a reflection of how long it takes the light of that object to reach us. Therefore, everything that we see actually happened in the past.
~
Astronomical objects just emphasize that fact because of their extreme distance.
