In the inset image at right, an arrow points to the stellar runaway and a dashed arrow to its presumed direction of motion. In the wider view of 30 Doradus, the homeless star, located on the outskirts of the nebula, is centred within a white box. The young star may have travelled about 375 light-years from its suspected home in R136, the bright star cluster marked by a circle. Nestled in the core of 30 Doradus, R136 is one of the most massive young star clusters in nearby galaxies, containing several stars topping 100 solar masses each. In the ESO and WFPC2 images, hot stars are represented by the color blue. Hydrogen is in red and oxygen in green. Radiation from the runaway star is making the nebula glow.
