About this image

Located 1,500 light-years from Earth within the plane of the Milky Way in the constellation of Cygnus, this large supernova remnant (SNR) occurred between 5,000 and 8,000 years ago. In its entirety the debris cloud has been sculpted by the shock wave from the star’s explosion, to form the Cygnus Loop object that we see today. The coloured light is created by the excitement of hydrogen (red) and oxygen(blue) gasses of the SNR, which is still expanding at about 100 km (60 miles) per second; image integration times for OIII & Ha wavelengths are in the ratio of 2:1 to enhance the weaker oxygen signal. The resulting image successfully brings out the exquisite nature of this exciting SNR, in particular highlighting the abundant waveforms that run throughout the entirety of his dynamic object.
