What is meant by -2*LogLikelihood in Gaussian Process model report?

I am applying Gaussian process model to my data set. But wondering what are the mathematical meanings of this -2LL (-2*LogLikelihood) term? Is there any formula for this (literature)?
I have searched in literature, I only found negative logLikelihood instead of -2*LL. Why JMP take twice of negative?
