Found: The First Double Star That BRIGHTENS During Eclipse

    First discovery of double star that brightens during eclipse

    Einstein's general theory of relativity explains the phenomenon

    by Dr. Ken Croswell

    For the first time, astronomers have seen a double star brighten rather than fade when one star passes in front of its companion. Predicted decades ago, the phenomenon arises from gravitational microlensing as the great surface gravity of a white-dwarf star magnifies its partner's light. The discovery by US researchers raises the hope that we will someday catch a neutron star or black hole doing the same thing, which would lend new insight into these extreme objects.
