Galactic Evolution: AI Could Soon Reveal Early Galaxies And Their Hidden Features

Artificial intelligence (AI) is being applied to a number of fields, but just recently, a group of researchers managed to train a deep learning algorithm -- a branch of AI -- to analyze images of distant galaxies and reveal how they formed and evolved over time. Understanding galactic evolution is one of the key puzzles in gaining more insight into the formation of our universe. We have a bunch of ground and space-based telescopes that can peer through the cosmos and capture these galaxies, but understanding every stage of evolution for an individual galactic candidate hasn't entirely been possible. This is because galaxies change their face over several billion years and our telescopes can only show how a galaxy looked at one particular period of time. As light from distant space objects takes millions to billions of years to travel, we always have the option to peer deeper into the cosmos and look back in time at other younger galaxies.
