A stellar graveyard in the sky
What’s left over after a massive star reaches the end of its life I hear you ask? Take a look for yourself. This Picture of the Week shows a small but very intricate portion of the Vela supernova remnant, the violent and yet beautiful aftermath of an explosive stellar death.
This dramatic scene played out around 11 000 years ago when a massive star in the constellation Vela went supernova. During this violent event, the star would have shined so brightly that it could be seen during the day.
The detailed and stunning view of both the gaseous filaments in the remnant and the bright blue stars in the foreground were captured using the 286-million-pixel OmegaCAM at the VLT Survey Telescope, hosted at ESO’s Paranal Observatory. OmegaCAM can take images through several filters that each let the telescope observe the light emitted in a distinct colour. To capture this image, four filters have been used, represented here by a combination of magenta, blue, green and red.
