About this Image
The colorful Pencil Nebula (NGC 2736) is part of the well known Vela Supernova Remnant at it's south-eastern end.
To our knowledge the 'bang' was probably some 11,000 years ago.
The expanding blast wave from the explosion is still sweeping outward from the site of the explosion.
The colorful structures are places where the blast wave has run into something, typically a clump or a cloud of interstellar material that is normally invisible.
