Postcard: Thor’s Helmet Nebula (NGC 2359) VLT (new)
This VLT image of the Thor’s Helmet Nebula was taken on the occasion of ESO’s 50th Anniversary in 2012. The helmet is a cosmic bubble, blown as the wind from the bright, massive star near the bubble’s centre sweeps through the surrounding molecular cloud.
