How are star systems—entire galaxies—born? How and why do billions of stars begin spinning around a common center? Does it happen all at once? Or little by little over the eons? These are big questions with lots of big answers. The problem is, which answers are right?
We can observe galaxies at many stages of their evolution, but it’s difficult because these galaxies are so very far away.
The Hubble Space Telescope (HST) has spied fuzzy blobs that might be galaxies in the making. Remember: Looking out in the universe means looking back in time. HST has seen galaxies as they were billions of years ago. Many observations of galaxies of all ages will help piece together the story of galaxy formation.
