X-rays in space typically come from extremely hot objects, often with temperatures in the range of millions of degrees Celsius to billions of degrees Celsius. Examples include plasma in the vicinity of black holes, neutron stars, and hot gas in galaxy clusters. Thus, both "millions of degrees Celsius" and "billions of degrees Celsius" could apply, but even higher energy X-rays can originate from objects with temperatures close to billions of degrees.
