Description

NGC 1968 is an emission nebula located in the Large Magellanic Cloud (LMC). Searches for NGC 1968 or N51D will allow further exploration about the surrounding objects on the frame. The large circular looking object near the centre has an interesting story. It is responsible for both heating the emission, and illuminating the reflection component of this nebula. The frame includes both emission and reflection nebula, plus an open cluster. The LMC is a place where many new stars are born. Many Young Stellar Objects (YSOs) can be located within this interesting nebula. YSOs are future stars that are in the initial development stages. In 2005, the Spitzer telescope located a Herbig Haro (HH) object located in the rim of the bowl-shaped structure. This is one of the first found and characterized outside of our own galaxy. HH objects are bright patches of nebulosity associated with newborn stars. They are created when narrow jets of partially ionized gas are ejected and collide with nearby clouds of gas and dust at high speeds. This phenomenon is indeed transient, lasting only a few tens of thousands of years. What makes this particularly interesting is that they can change visibly over short time scales (a little as a few years) as they move quickly away from their parent star.



The complete data for this object was made available the “The Astro Imaging Channel” workshop that was presented on the 15th of July 2019. The set includes traditional Lum R G B masters (18 hours worth), plus an additional 45 hours of narrowband data. Participants shared how they worked through the data.

This image presented is a black and white rendition using both narrowband and broadband data.
