There is something in space called the Zone of Avoidance.
The name sounds like something out of a horror movie. In 1878, it was originally called the Zone of Few Nebulae.
But what is it? It's the area of the sky that is obscured by the Milky Way.
The interstellar dust and stars in the galactic plane of the Milky Way obstructs our view by around 20% of the extragalactic sky.
Galaxy catalogues are usually incomplete in this area.
Even with modern advances like infrared and X-Ray astronomy, around 10% of the sky still remains difficult to survey. Extragalactic objects can be confused with stars in our Milky Way.
Infrared and radio regions of the electromagnetic spectrum have shown that many external galaxies lie beyond it.
