At the Movies 
(my random, rarely-updated visualization blog)

This is a podcast/blog dedicated to astrophysics movies, particularly themed towards my own interests in getting this in the public eye, through classrooms, planetaria, websites like this one and of course big ones like YouTube. Basically, there’s a huge wealth of simulators making these beautiful and incredibly instructive visualizations, and painfully little being done to really take advantage of it all for relating to the public how cool space and physics can be!

At the movies (for real!)

Ok, time for this incredibly sparsely-updated video collection to earn its’ name! I finally feel like I’ve settled in LA, since Jessie and I, together with Chris Hayward and his wife Tara, got to go to the premiere of Terrence Malick’s Voyage of Time. (Featuring, of course, some of our animations). Caltech put together a featurette on it, which you can watch here. Super-fun! If you’re curious, we contributed the animation of galaxies colliding in the first few minutes of the IMAX cut, along with a couple others. You can see more of ours, with additional discussion and narration, here:


Above is a video explaining the breakthroughs and new physics in our “Latte” simulations, the highest-resolution simulations of a Milky Way like galaxy that have ever been run to the present day, presented in Wetzel et al. 2016 (

Illustris Simulation Movies

The folks behind the Illustris simulations (similar to the EAGLE runs described in a previous post: large-volume cosmological simulations) have put together some beautiful visualizations. See more at

The Original Galaxy Simulations

This is what the first galaxy simulations looked like! See for more details

Metal Stars!

Sarah Willis, a postdoc at the CfA, wrote a program for SciShow Space on our ‘Totally Metal Stars’ Work: for great explanations and cool movies of the process in action, with smart people commenting, check out:

New Movies! (Cosmological Simulations)

Bunches of new movies of our FIRE cosmological simulations, uploaded to the site. See them here and here!

For other movies of our simulations, check the following:

Movies of isolated galaxies with powerful outflows driven by supernovae and other forms of feedback from young, massive stars

Movies of galaxy mergers between those same galaxies 

Movies of galaxy merger simulations with outflows driven by accreting black holes instead of massive stars

Movies of “Zoom-In” simulations that follow gas from a merger down to ~0.1 parsec scales as it accretes onto a super-massive black hole

Movies of cosmological simulations, where we follow the formation of galaxies over cosmic time, with powerful outflows driven by feedback

Movies of a fly-through of a Milky-Way like galaxy, formed in cosmological simulations, showing various properties

Rob Crain’s EAGLES Movies

Over at

Rob Crain has set up a vimeo channel for his movies with Typhoon, a visualization tool, mostly designed around cosmological simulations. Some awesome stuff! And good advertising for the EAGLE project, a counterpart to the Illustris simulation, and the next-generation in large-volume cosmological simulations.

Movies of our Simulations Across the Web

In the previous post I dumped a bunch of movies from my own collection on you. Here are some others from the web, which (selfishly) is biased towards my own movies, just because I had the links. Check out the channels though, of these dedicated YouTube users who’ve compiled really great stuff.

Getting Started

To start, I want to share what I’ve put together myself, for use in talks, teaching, etc. 

As this blog progresses, I hope to individually highlight these movies and tell you more about what’s happening in them, but first, the “core dump”: go to

That’s all of it -- I’m showing you all the movies I’ve compiled for different talks, and all the ones I’ve made (not just the prettiest ones!). I want whomever is interested to be able to browse them. If you want to use one, please do! Just let me know, so we can make sure proper credit is given where it is due.
