Sharpest Image Ever of R136a1, Largest Known Star

Nestled in the center of the Tarantula Nebula in the Large Magellanic Cloud is the largest star yet discovered. With the help of the Zorro imager and the power of the 8.1-meter Gemini South telescope in Chile, astronomers have produced the sharpest image ever of this star. This new image challenges our understanding of the most massive stars and suggests that they may not be as massive as previously thought.
