This galaxy (probably) does not exist
I've created NN to generate galaxies based on Hubble telescope photos.
Generative models are now the top trend in CV. Their marriage with NLP made them even more interesting, and the stuff that DALL-E 2 does is amazing.
However, GANs are still rolling as well.
I am always interested in astrophysics on an amateur popular science level. After listening to Niel DeGrasse Tyson and reading “The Three-Body Problem” novel by Liu Cixin (both highly recommended btw) I came to an idea to train StyleGAN for galaxies image generation.
So, I collected photos - real ones - of the Hubble telescope, which took some time and let the model train. Here is the result, have a look. So far the resolution is 512x512, but I will work on further improvements.
Let me know if you need the dataset and more details on the model itself.
