# Meet A1689B11 : The oldest spiral galaxy ever discovered

Having redshift value $z=2.54$ A1689B11 belongs to a population of rare spiral galaxies at redshift $z\gtrsim 2$ that mark the formation epoch of thin disks. Future observations with NASA’s James Webb Space Telescope will greatly increase the sample of these rare galaxies and unveil the earliest onset of spiral arms. This discovery is a major breakthrough and is said to reveal more information about the earlier stages of universe.
