Molten Ring NGC 4039 After being studied with telescopesGravitational lensing was predicted by Einstein's theory of General Relativity, but we have to wait many years to see this on such a scale. In this particular snapshot, a science discovery followed the release of a Hubble observation of a striking example of a deep space optical phenomenon dubbed an "Einstein ring." The photo was released in December 2020 as an example of one of the largest, nearly complete Einstein rings ever seen. In this image, a
