Black hole shock: NASA warns 'sinister' monsters are hidden 'in every direction you look'

“Monsters lurk in the shadowy depths of the universe, sometimes hidden in plain sight.

“Many of them are invisible to our eyes, so we have to use special telescopes to see them.”

Rogue asteroids and comets are another of the “monsters” inhabiting space.

In an eerie twist of events, astronomers in 2015 discovered an icy comet with an incredibly skull-like appearance.

The so-called Halloween Asteroid or Great Pumpkin has since been confirmed to most likely be a dead comet.
