Scientists have demonstrated how ‘dancing black holes’ create a glare that is brighter than a trillion stars, with the help of data from the now-retired Spitzer. The black hole duo named OJ 287, exists about 3.5 billion light-years from Earth. Scientists from the Tata Institute of Fundamental Research, Mumbai created a model of the irregular and elliptical orbit followed by the smaller black hole around the bigger one. They proved that by precisely predicting a flare that occurred on July 31, 2019, and this observation was only achievable with the help of Spitzer. With the data, scientists were able to prove the efficiency of a model that predicted how a black hole orbits another black hole in space.
