Image of the star WOH G64 side-by-side with an artistic reconstruction

Located in the Large Magellanic Cloud, at a staggering distance of over 160 000 light-years from us, WOH G64 is a dying star roughly 2000 times the size of the Sun. This image of the star (left) is the first close-up picture of a star outside our galaxy. This breakthrough was possible thanks to the European Southern Observatory’s Very Large Telescope Interferometer (ESO’s VLTI), located in Chile. 

The new image, taken with the VLTI’s  GRAVITY instrument, shows that the star is enveloped in a large egg-shaped dust cocoon. The image on the right shows an artist’s impression reconstructing the geometry of the structures around the star, including the bright oval envelope and a fainter dusty torus. Confirming the presence and shape of this torus will require additional observations.
