Watch a Galaxy Form Over More Than 13 Billion Years
Scientists had to speed the simulation up just a little bit.
Using a powerful supercomputer, scientists have created a state-of-the-art simulation of galactic formation.
While previous simulations typically had to choose between showing a big-picture view or being highly detailed, the TNG50 simulation is both. Not only does it show how a whole universe may have formed in the 13.8 years since the Big Bang, but it also gives scientists the ability to zoom in and see an individual galaxy form in incredible detail.
Perhaps most exciting of all: the team behind TNG50 shared a clip of one of those simulated galaxies online for your viewing pleasure.
TNG50 was a collaborative undertaking between scientists in Germany and the United States, who published two papers on the simulation in the journal Monthly Notices of the Royal Astronomical Society earlier in November.
It took the Hazel Hen supercomputer in Stuttgart, Germany, more than a year to complete the simulation, which — like similar visualizations — largely works backwards from what scientists already believe about the universe to predict the activity that led to the current state of affairs.
While being able to see a galaxy form over billions of years is cool in and of itself, the simulation did more than just produce a visual for known data — it also provided several new insights, including previously unknown details on the process of disc galaxy formation.
“Numerical experiments of this kind are particularly successful when you get out more than you put in,” researcher Dylan Nelson said in a press release. “In our simulation, we see phenomena that had not been programmed explicitly into the simulation code. These phenomena emerge in a natural fashion, from the complex interplay of the basic physical ingredients of our model universe.”
The researchers plan to eventually release all of the data from TNG50, giving other scientists the opportunity to look for even more new phenomena in the state-of-the-art simulation.
