NASA's Chandra X-ray telescope has made the first detection of X-ray emission from young solar-type stars that lie outside our Milky Way galaxy. They live in a region known as the 'Wing' of the Small Magellanic Cloud, a satellite galaxy of our Milky Way. X-rays from young stars trace how active their magnetic fields are. Magnetic activity provides clues to a star's rotation rate and the rising and falling of hot gas in the star's interior. Astronomers suggest that if the X-ray properties of young stars are similar in different environments around our galaxy, then other related properties, such as the formation of planets, are also likely to be similar.
