We live in an era when viewing the universe is possible through much more than an inspiring look into the dark, nighttime sky. Tools such as the Hubble Space Telescope have brought to our earthbound eyes images of worlds, galaxies and nebulae—awe-inspiring vistas reminding us that the universe our Father has created is truly a vast expanse of variety and wonder!

What is the most complex object in the cosmos? This is a big question—galaxies comprise hundreds of billions of stars and planets, and could be considered complex, as could many other natural structures. Among mankind’s creations are some remarkable works of vast intricacy. Europe’s powerful particle accelerator, the Large Hadron Collider, is an engineering feat of great complexity, and in its day the United States’ Space Shuttle was called the most complicated machine ever invented.
