The most massive known star may be smaller than thought, image shows

The universe’s most massive known star just got its best close-up ever, revealing that the star may be smaller than astronomers previously thought.

Astronomers using the Gemini South telescope in Chile photographed the star R136a1located about 160,000 light-years from Earth at the center of the Tarantula Nebula in the Large Magellanic Cloud – a dwarf companion galaxy of the Milky Way. Their observations show that the giant star (and others who like it) may not be as massive as previously thought.
