Yes there is. The Old Testament speaks little about what it's like after death, but when we get to the New Testament and Jesus, the light of revelation illuminates even this dark reality. Jesus says about hell that it was not originally prepared for people but for the Devil and his angels. Hell is described as eternal fire, a lake of fire, darkness, separation, weeping, and gnashing of teeth. Since we cannot say how concretely these images should be understood, I think we can settle for a definition like this: Hell is eternal separation from God and all His goodness.

A Christian should not be so much interested in hell as in how to avoid it. And let us remember that Jesus did not come into this world to scare us with hell, but to redeem us for heaven. You too!

Then he will say to those on his left, ‘Depart from me, you cursed, into the eternal fire prepared for the devil and his angels.
(Matthew 25:41, ESV)
