NGC 5559 – Spiral Galaxy

In this image, taken by the Hubble Space Telescope, you can see NGC 5559. It is a spiral galaxy, located in the constellation of Boötes (The Herdsman, https://goo.gl/AQKKvX), about 240 million light-years away from Earth.

NGC 5559 is a typical spiral galaxy (https://goo.gl/D3uAeP) with visible arms and ongoing star formation (https://goo.gl/Mn2Zxf).

In 2001 NGC 5559 was home to supernova 2001co, a calcium-rich supernova (https://goo.gl/4Q6HpA). Only 15 supernovae have to date been classified as this type, they are less luminous than other types of supernovae and have a quick cycle of gaining brightness and fading away.

NGC 5559 was discovered April 10th, 1785, by the English astronomer William Herschel (https://goo.gl/E9YsKH).
