Have astronomers finally found an exomoon? (w/video)

International researchers have found a new candidate for an exomoon - a moon that orbits planets beyond the realm of our Solar System. If its exomoon status is confirmed, Kepler-1708 b-i - which is 2.6 times larger than Earth - could represent a missing piece in the puzzle to understand the formation and evolution of planetary systems long ago in galaxies far, far away.

The search for an isotropic gravitational wave background

An international team of astronomers has announced the results of a comprehensive search for a background of low-frequency gravitational waves. These light-year-scale ripples, a consequence of general relativity, permeate all of spacetime and could originate from mergers of the most massive black holes in the Universe or from events occurring soon after the formation of the Universe in the Big Bang.
