Six of the hundreds of ‘anomalies’ discovered in the Hubble telescope archives, including three unusual galaxies and three gravitationally lensed objects. An artificial intelligence (AI) tool has uncovered more than 1,000 strange cosmic objects in the Hubble Space Telescope's image archive, including some that cannot be explained by science. "Archival observations from the Hubble Space Telescope now stretch back 35 years, providing a treasure trove of data in which astrophysical anomalies might be found," O'Ryan wrote in the paper. One of the new Hubble anomalies is a 'collisional ring' galaxy, formed when one galaxy smashes into the center of another. "The discovery of so many previously undocumented anomalies in Hubble data underscores the tool's potential for future surveys."
