NGC 7469 undergoes an abnormal burst of star formation resulting from the star burst, some clumps that house clusters of red giant stars are revealed within these spiral arms. The cause of the starburst is still unknown. The left-hand image has been recorded with the adaptive optics compensation turned "on". The right-hand image is a simulation of what can typically be achieved from a good ground-based telescope without an adaptive optics system. The angular resolution is 0.13 arcsec in the left-hand image and 0.7 arcsec in the right side image. The field of view is 10x10 arc seconds. The diffraction limit of the Gemini telescopes corresponds to an angular resolution of 0.045 arcsec at 1.6µm.
