Hello,
This faint object also known as Pencil Nebuladue to its linear shape, is located in constellation Vela being almost the only sign of the eastern part of this vast bubble of expanding shock wave from a stellar explosion 12,000 years ago.
Lying about 815 light years from Solar System, it falls in the same galactic environment as the Vela nebula, of which probably the Pencil Nebula constitutes the most eastern part. It is a filamentary and very soft structure , which moves in space from west to east at a speed of about 644,000 km / h .
