Our precious little earth

This was sent by a friend and I couldn't not put it on the blog - their is no credit about where it came from so I hope the originators wont mind. Antares is the 15th brightest star in the sky - it is 1000 light years away!!! Arcturus meanwhile is the third brigtest but much nearer - that is the tiny orange circle in the first picture and the much larger in the second. This really is something to ponder on.....
