We report the first observation of the doubly strange b baryon Omega-_b in the decay channel Omega-_b to J/psi Omega-, with J/psi to mu+ mu- and Omega- to Lambda K- to (p pi-)K- in ppbar collisions at sqrt{s} = 1.96 TeV. Using approximately 1.3 fb-1 of data collected with the D0 detector at the Fermilab Tevatron Collider, we observe a signal with 5.4 sigma.
