“The researchers used new observations made with HST, shown above, which shows that N6946-BH1 is no longer there in the visible spectrum, but a faint signal in the near-infrared is present.
Based on the data and models, the scientists believe the data points toward the formation of a black hole, with the thermal emission being created by accretion material entering the black hole.”
