NASA’s Hubble Space Telescope has captured an image of a galaxy with a unique and record-breaking feature: nine star-filled rings. this galaxy, known as LEDA 1313424 or the “Bullseye Galaxy,” is about 2.5 times the size of the Milky Way and is located far away from Earth.
The rings were discovered using the Hubble Space Telescope and additional observations from the Keck Observatory. This revelation is significant because previously, astronomers had only found galaxies with at most two or three rings. The formation of these rings is believed to be the result of a collision with a smaller blue dwarf galaxy, which acted like an “arrow” that caused the ripples in the larger galaxy.
Researchers suspect that there might potentially be a tenth ring, but it is indeed currently undetectable. They estimate it is three times farther from the galaxy’s center than the widest visible ring.
The discovery of LEDA 1313424 was accidental, but astronomers expect to find more galaxies like this in the future. The upcoming launch of NASA’s Nancy Grace Roman Space Telescope in May 2027 is expected to reveal many more interesting objects due to its larger field of observation, which is at least 100 times larger than that of the Hubble Space Telescope. The Roman Space Telescope is also designed to block starlight and directly observe exoplanet and planetary structures, contributing to research in dark energy, exoplanets, and infrared astrophysics.
The findings were published in the Astrophysical Journal Letters on February 4, 2025.

Teh NASA Hubble Space Telescope has unveiled the “bullseye Galaxy” (LEDA 1313424), a galaxy boasting an amazing nine star-filled rings. Astronomers discovered this unusual formation using the Hubble Space Telescope and additional observations from the Keck Observatory.This stunning finding highlights significant advancements in our understanding of galaxy formations and celestial collisions.
Interview with Dr.Emily Walker
In this interview, Senior Editor Jeff Black speaks with Dr.Emily Walker, an expert astronomer at the Keck Observatory, about the groundbreaking revelation of the “Bullseye Galaxy”.
discovery and Formation of the Rings
Jeff Black: Dr. Walker, could you tell us what led to the discovery of these unique rings in LEDA 1313424?
Dr. Emily Walker: The discovery was accidental but was possible because of highly detailed observations from the Hubble Space Telescope. We noticed unusual structures within the galaxy that, upon closer inspection, revealed a series of nine vivid rings. This is significant as previously, astronomers had only found galaxies with a maximum of two or three rings.
The Dynamics Behind Galaxy Collisions
Jeff Black: Can you explain how such a unique structure comes into existence?
Dr.Emily Walker: The formation of these rings is believed to be a result of a collision with a smaller blue dwarf galaxy. This collision acted like an “arrow” that caused ripples in the larger galaxy, creating these concentric star-filled rings. Such dramatic events give us insights into how gravity and celestial dynamics shape galaxies.
Potential for More Rings
Jeff Black: There is a suspicion of a potential tenth ring.Can you discuss this possibility?
Dr.Emily Walker: We suspect there could be a tenth ring, but it is currently undetectable. Estimates suggest it would be three times farther from the galaxy’s center than the widest visible ring.This further emphasizes the complexity of galactic interactions.
Future Discoveries
Jeff Black: What do you expect from the upcoming launch of NASA’s Nancy Grace Roman Space Telescope?
Dr. Emily Walker: The Roman Space Telescope,set to launch in May 2027,has a much larger field of observation—at least 100 times larger than Hubble’s. It is indeed designed to block starlight and directly observe exoplanets and planetary structures. We anticipate many more remarkable discoveries, contributing to research in dark energy, exoplanets, and infrared astrophysics.
Jeff Black: How significant is this discovery in the broader context of astrophysics?
Dr. emily Walker: This discovery underscores the importance of galactic interactions and the beauty of cosmic collisions. It brings us closer to understanding the magnanimous complexity of the universe and our place within it.
