Eccentric

For the first time, scientists believe they have detected a merger of two black holes with eccentric orbits. According to a paper published in Nature Astronomy by researchers from Rochester Institute of Technology's Center for Computational Relativity and Gravitation and the University of Florida, this can help explain how some of the black hole mergers…

Using data from NASA’s Transiting Exoplanet Survey Satellite (TESS) and several ground-based facilities, astronomers have discovered a long-period sub-Neptune exoplanet orbiting TOI-2257. Intriguingly, the planet’s orbit is highly elliptical, suggestive of a possible perturbing outer gas-giant planet in the TOI-2257 system.
