Large metallic cylinders with a mass of several tons have been cooled to liquid helium temperatures and recently down to T ~ 100 mK leading to the most sensitive gravitational wave detector (NAUTILUS). The sensitivity is still not enough to detect waves from distances so large that the number of events becomes several per year. Cooling spherical detectors with a mass around 100 tons to temperatures around 10 mK could achieve this goal giving rise to a new astronomy.
