The Beauty of Galaxy Formation (Simulation Videos)

Well, we all know just how beautiful our very own Milky Way Galaxy is…

Mily Way Galaxy

But how much thought have you put into how these galaxies form? For starters, and to give some frame of reference, it takes billions of years for a galaxy to form. And considering that humans live less the 100 years on average, this truly puts things in perspective (i.e., creating beauty takes time… a lot of time).

NASA’s Goddard Space Flight Center has really done something incredible. Simulating the formation of how a galaxy is formed (while also identifying some interesting trends), like I’ve never seen in such astonishing detail.

Here is a video simulating a galaxy being formed:

… thank you NASA (and the universities associated with this project, and all others) for being relentless in your effort to further strengthen our understanding of the universe .


  • note: To simulate 13.5 billion years in the life of a single disk galaxy, NASA needed more than your average desktop PC. The memorable video below is the direct work of the agency’s Pleiades supercomputer and, by NASA’s estimates, approximately 1 million CPU hours.
