In this image, taken by the Hubble Space Telescope, you can see NGC 6753. It is a spiral galaxy (https://goo.gl/D3uAeP), located in the constellation of Pavo (The Peacock, https://goo.gl/6GQKNp), about 150 million light-years away from Earth.
NGC 6753 is close enough – in astronomical terms – to allow for detailed studies of its galactic corona (https://goo.gl/aWpeVo). A giant sphere of invisible hot gas surrounding the galaxy.
The blue areas in the spiral arms are zones of ongoing star formation (https://goo.gl/Mn2Zxf).
NGC 6753 was discovered on July 5th, 1836, by the English astronomer John Herschel (https://goo.gl/WCo123).
