Bouma, Andrew Boyle, and Andrew Mann from the University of North Carolina Chapel Hill combined data from NASA's TESS mission, ESA's Gaia spacecraft, and the Sloan Digital Sky Survey (SDSS).
NASA's TESS mission detected light from both black holes in OJ287.
NASA's TESS mission provides large datasets crucial for studying comets, asteroids, and interstellar objects.
An extended TESS mission lasting a little more than two years from mid-2020 to late 2022 is planned to revisit some areas observed in the prime mission and fill in gaps not observed.
