An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research about the possible formation of large moons following the collision of two planets. Megan Bruk Syal and Amy Barr of the Lawrence Livermore National Laboratory conducted a series of simulations to understand what factors influence the birth of big moons. This study offers new hope in the search for exomoons orbiting exoplanets studied with NASA’s Kepler space telescope.
