NASA Published Composite Image of Black Eye Galaxy
The composite view uses infrared and visible light data to reveal the complex gas dynamics of a galaxy 17 million light-years away.
Updated on Sept. 19, 2026 in Space
NASA has released a new composite image of the Black Eye Galaxy, merging data from the James Webb Space Telescope and the Hubble Space Telescope. The image highlights the galaxy's distinct dust band and the counter-rotating gas streams that provide evidence of a past galactic merger.
Why it matters
Analyzing the structure of the Black Eye Galaxy allows researchers to better understand galactic evolution and the long-term impact of mergers on star formation. This data offers a refined look at how external material influences the internal dynamics of a galaxy over a billion-year period.
The image incorporates data from the James Webb Space Telescope's Mid-Infrared Instrument, which detects infrared radiation to map dust and embedded young stars. This instrument provides a clearer view of the obscured regions compared to traditional optical sensors.
The players
NASA
The United States government agency responsible for the space program, aeronautics research, and the operation of long-range space telescopes.
James Webb Space Telescope
An infrared observatory capable of peering through cosmic dust to capture the oldest and most distant objects in the universe.
Hubble Space Telescope
A long-serving space-based observatory providing high-resolution imagery in the visible and ultraviolet spectrums.
The details
The Black Eye Galaxy features outer gas regions that rotate in the opposite direction to its core, a phenomenon caused by a merger with a smaller satellite galaxy. The Mid-Infrared Instrument, an onboard sensor designed to detect heat-based infrared radiation, penetrates the galaxy's prominent dark band of dust. Compressed gas clouds within this band trigger the gravitational collapse of material, leading to the formation of new stars.
Timeline
A merger with a smaller satellite galaxy occurred over a billion years ago.

The Tech Race
This imaging effort follows the methodology of the NASA James Webb Space Telescope galactic survey program. The study of the Black Eye Galaxy advances the research community's ability to map merger histories by comparing high-resolution infrared data against existing optical records.
The composite image is now available for public viewing, providing a clearer look at star-forming regions within the galaxy. Researchers expect this data to facilitate future studies on how dust and gas interactions influence the long-term morphology of galaxies.
The takeaway
The observation confirms that internal gas rotation patterns act as a structural record of ancient cosmic collisions. Readers can watch for future peer-reviewed findings that use this combined dataset to map the full timeline of the Black Eye Galaxy merger.
