Astrophysicists discover planets in extragalactic galaxies using microlensing (https://phys.org/news/2018-02-astrophysicists-planets-extragalactic-galaxies-microlensing.html)
QuoteA University of Oklahoma astrophysics team has discovered for the first time a population of planets beyond the Milky Way galaxy. Using microlensing—an astronomical phenomenon and the only known method capable of discovering planets at truly great distances from the Earth among other detection techniques—OU researchers were able to detect objects in extragalactic galaxies that range from the mass of the Moon to the mass of Jupiter...
Astonishing, utterly astonishing,
Cor bliney!
Very cool... Had to look up microlensing:

WOW! :scratch:
That is amazing. I think our newly-acquired resident physicist will be able to enlighten us when these topics come up.
