Our researchers developed an AI tool that allows them to inspect millions of astronomical images in a fraction of the time it would take a human.

They developed what’s called a neural network, an AI tool that uses computers to process data and search for patterns in a way that is inspired by the human brain. Their neural network, is trained to search for and recognise rare objects like jellyfish galaxies and gravitational arcs.
The team trained their tool and demonstrated its capabilities using the Hubble Legacy Archive. They sifted through nearly 100 million image cutouts in just two and a half days, uncovering nearly 1400 anomalous objects, more than 800 of which had never been documented before.

Most of the anomalies were galaxies in the process of merging or interacting, taking on unusual shapes or trailing long tails of stars and gas. Many others were gravitational lenses, in which the gravity of a foreground galaxy bends spacetime and warps the light from a distant background galaxy into a circle or arc.

The team also discovered examples of several other rare objects such as galaxies with huge clumps of stars, jellyfish galaxies with gaseous ‘tentacles’, and planet-forming disks seen edge-on, giving them a hamburger-like or butterfly-like appearance. Perhaps most intriguing of all, there were several dozen objects that defied classification altogether.
