2I/Borisov is the second interstellar object to visit our solar system. Where could it have come from?

This paper seeks to provide a theoretical explanation for why gravitational perturbations do not disrupt the Keplerian orbits of Earth’s satellites.
This paper presents the first evidence of two distinct populations of pulsars, which the authors speculate stem from a difference in how they are formed.
