The concept of hell is usually tossed around in religious discourse as the exact and dreadful opposite of heaven.
Although in a realistic sense, the place of fiery pits and eternal despair can actually be found in space—a planet, that is.
Wonderful Engineering recently reported the discovery of Cancri 55 e, a planet that uncannily matches the descriptions our elders and parish priests tell us of hell.
Both of its hemispheres are simply infernal. One is blanketed with darkness, while the other burns with lava on the surface.
The sun isn't even an encouraging sign; the side of the planet facing it can reach temperatures as high as 2,000 degress Celsius. Cancri's night side is as instantaneously lethal at 1,500 degrees Celsius.
Its atmosphere, is literally a poisonous gas called hydrogen cyanide, and emits high levels of radiation indicating an, imminent, Frieza saga-type of self-destruction.
The only thing missing, really, are the harrowing echoes of lost souls and Hitler.
