It lies approximately 26 million light years from Earth, and is 87,000 light years in diameter. It was discovered by Sir William Herschel in 1798. Due to its prodigious star formation rate, it has been classified as an active starburst galaxy. It has also been the host to numerous supernovas, the last one occurring in 2017. It has been nicknamed "The Fireworks Galaxy".
