The Vela Supernova Remnant is an endless source of beautiful images. The delicate fine structure of its wisps, carefully separated into Hydrogen-rich and Oxygen-rich emitting regions, offers multiple opportunities for a detailed close-up. Please, see a wide field mosaic of this remnant here.

This region, located at the Eastern border of the remnant, shows greenish-blue Oxygen III “threads” above the “tortured” red Hydrogen clouds below. For some more information about this remnant and some more detailed images, please see also here.

This image is part of an ongoing joint project with Christian Sasse.
