Stars in the Magellanic Clouds
The Magellanic Clouds are two irregular galaxies, or nebUlae, just outside the Milky Way Galaxy. They were first recorded by the Portuguese navigator Ferdinand Magellan during the first voyage around the world. They can be seen with the unaided eye in the southern hemisphere.
The Large Magellanic Cloud (LMC) is 150,000 light-years from the Earth, and the Small Magellanic Cloud (SMC) is 200,000 light-years away.
The Magellanic Clouds are younger than the Milky Way. They contain many young stars and star clusters.
 This is a picture of the self- destruction of a massive star called Supernova 1987A in
the Large Magellanic Cloud. The explosion was observed first on February 23, 1987, although it took place 150,000 years ago, because the star is 150,000 light-years away. This picture shows the supernova remnant, surrounded by inner and outer rings of material. The many bright blue stars near the supernova are massive stars, each more than six times more massive than our Sun.
 This picture shows the Small Magellanic Cloud with young, ultrabright stars nested in their cloud of glowing gases. There are 50 separate stars tightly packed in the core. These young stars are sending out huge stellar Winds that are buffeting the walls of the nebula. The pair of bright stars in the center of the nebula is sending out the ultraviolet radiation that makes the nebula glow.
This is a true-colour view.
