Astronomers have recently discovered a new population of planets outside our Milky Way galaxy in the Small Magellanic Cloud (SMC). This is the first time that planets have been found in another galaxy, and it opens up a new field of research in galactic astronomy. The planets, which have masses similar to those of Earth, were detected by the Hubble Space Telescope. The researchers believe that these planets could provide new insights into how planets form and how galaxies evolve. This discovery has implications for the search for extraterrestrial life, as it indicates that galaxies could host a variety of planets that could potentially be habitable.
