NGC 1999 HaLRGB

NGC 1999 has a huge hole of empty space appearing as a black patch in its central region. It’s a reflection nebula, shining from the light of V380 Origins variable star.

The black patch is not a dense cloud of dust and gas but a truly empty hole.

The nebula is about 1,500 ly from Earth in the constellation Orion.
