ISOHDFS 27 is a spiral galaxy in the constellation Tucana, and was discovered in the Hubble Deep Field South survey. It is the most massive spiral galaxy found in the survey,[1] measuring 130,000 light-years (40,000 parsecs) in diameter.[2] It is located approximately 6 billion light-years (1.8 billion parsecs) from Earth[2] and has a mass greater than 1000 billion times the mass of the Sun, making it about four times as massive as the Milky Way.[1]

It was once the largest known spiral galaxy,[1] but it has since been dethroned by NGC 6872.[3]
