For me the Hubble Space Telescope photos are absolutely fascinating. I have posted on this topic previously so you can see even more space photos at my article Photo Gallery: Look at the Heavens.
In Psalm 19 David composed the lyrics to a song. He expresses his amazement of outer space.
To the choirmaster. A Psalm of David. The heavens declare the glory of God, and the sky above proclaims his handiwork. Day to day pours out speech, and night to night reveals knowledge. There is no speech, nor are there words, whose voice is not heard. - Psalm 19:1-3 ESV
I can only imagine the wonder that David would have expressed if he were able to use today's technology to see the stars.
This photo was released last year to celebrate the Hubble Space Telescope's 22nd year of operation. According to NASA, this photo shows part of the Tarantula nebula. Wikipedia reports that this star-making region is located almost 160,000 light years away.
