That's one of my favorite aspects of astronomy. To the universe, we're (Earth) just a spec on a dot. The stepping away from all of the things that seem so stressingly important and realize that it's only us that feels that stress and the universe really absolutely doesn't give a shit. It always helps me to give less of a shit too.
So true. If I happen to be do something new, high risk or making me stress out thinking about it in context of the larger universe (and staring at these pictures help) quickly puts me at ease. Very effective. I have passed this to others over the years.
