A groundbreaking discovery has been made in the distant galaxy OJ 287, revealing the presence of two black holes. This finding, confirmed by NASA’s Transiting Exoplanet Survey Satellite (TESS), sheds new light on the mysterious nature of black holes and their behavior.
The research, initially suggested by astronomers at the University of Turku, Finland, has now been supported by several international research groups. TESS, designed to detect exoplanets, turned its gaze towards OJ 287 to help verify the existence of the two black holes. This far-reaching mission aims to uncover thousands of exoplanets orbiting dwarf stars, expanding our understanding of the diverse planetary systems in our galaxy.
In a recent study, TESS observed a sudden burst of brightness, indicating the presence of the smaller black hole orbiting the larger one. This intriguing event, accurately predicted by researcher Pauli Pihajoki in his dissertation, had never been witnessed in OJ 287 until now. The burst illuminated the surroundings with such intensity that it rivaled the combined brightness of 100 galaxies.
The short-lived burst was captured by TESS during a 12-hour period on November 12, 2021. The precise timing of this event, as predicted by the Turku researchers, enabled TESS and other telescopes, including NASA’s Swift telescope, to focus on OJ 287 at just the right moment. The discovery was further validated by a large international collaboration and a group from Boston University, who utilized telescopes in various locations across the globe.
Combining all the available observations, Professor Mauri Valtonen and his research team at the University of Turku concluded that the burst of light originated from the smaller black hole and its surroundings. This breakthrough provides valuable insights into the behavior and dynamics of black holes in binary systems.
The implications of this discovery extend beyond our current understanding of black holes, paving the way for future research endeavors. By unraveling more mysteries surrounding these cosmic powerhouses, scientists can deepen their understanding of the universe and its fundamental laws. With each new observation, we come closer to comprehending the enigmatic nature of black holes and their role in shaping the cosmos.
