• •A new study, published in The Astrophysical Journal, used machine learning to study the size of galaxies in different environments.
• •The study found that galaxies in denser regions of the universe can be as much as 25% larger than galaxies with a similar mass and shape in less dense regions.
• •The study was led by Aritra Ghosh, a postdoctoral fellow at the University of Washington.

Astronomers use machine learning to study 2.8 million galaxies and discover that galaxies in denser regions of the universe can be as much as 25% larger than galaxies with a similar mass and shape in less dense regions.
