The "Pencil Nebula" is a large shockwave that is traveling at oustanding speeds. It is traveling at around 500,000 Km per hour. I can see why it is called the Pencil Nebula, due do it being a long thin line with smaller red ones that are being emitted from behind. It may seem strange, but it kind of reminds me of a beta fish. This nebula is 5 light years long and 800 light years away, making it close compared to other nebulas. It has been identified as a remnant of the Vela Supernova. When the supernova occured, the shockwaves were moving at millions of miles per hour, but has since slowed down to 500,000 Km per hour. In my opinion. it's one of the most interesting looking nebulas around.
I agree, it is one of the most interesting nebulas around, also i do see where you picture a beta fish haha!!
