Comment: Article writing style is very good but it srill need more secondary sources most of them are catalogs with only one useful NASA article Abdullah1099 (talk) 07:32, 23 June 2026 (UTC)

AM 2026-424 (also designated as ESO 285-19) is a system of interacting galaxies located approximately 704 million light-years (216 megaparsecs) away in the southern constellation of Microscopium.[2] It is classified as a collisional ring galaxy, formed as the result of a violent, head-on galactic collision.[5]
Observation and cataloging
editThe system was first cataloged in the Catalogue of Southern Peculiar Galaxies and Associations (AM Catalogue), compiled by astronomers Halton Arp and Barry F. Madore in 1987.[5] It consists of two principal galactic components or nuclei: the western component cataloged as PGC 64801, and the eastern component cataloged as PGC 64805 (also designated as ESO 285-19A).[4]
In October 2019, the Hubble Space Telescope released a detailed image of the system captured by its Advanced Camera for Surveys (ACS).[6] Due to the positioning of the two bright nuclei resembling eyes, surrounded by a ring of star formation that mimics the outline of a face, science media outlets widely reported on the target under the popular nicknames the "Ghostly Face" or "Cosmic Face".[7][8]
Characteristics
editThe ring structure of AM 2026-424 spans roughly 200,000 light-years across, which is nearly twice the diameter of the Milky Way.[2] Unlike stable ring galaxies like Hoag's Object, which feature a symmetric, isolated ring surrounding a single core, AM 2026-424 is a short-lived transitional structure.[5] The head-on collision pulled and stretched the galaxies' disks of gas, dust, and stars outward, triggering a massive wave of starburst activity that forms the temporary ring envelope.[7]
Because the two galactic nuclei are still distinctly visible and separate, astronomers determine that the two colliding galaxies were of roughly equal size prior to the impact.[8] This disrupts the more common cosmic scenario where a larger galaxy cannibalizes a much smaller companion.[6] The system is expected to fully merge into a single, larger galaxy over the next few hundred million years.[7]
