Astronomers Capture First Detailed Image of Distant Giant Star

Astronomers have captured the first close-up image of WOH G64, a massive red supergiant star in the Large Magellanic Cloud, using the Very Large Telescope Interferometer in Chile. This achievement provides new insights into the final stages of massive stars' lives, revealing a complex, asymmetric envelope of gas and dust surrounding the star. The observations highlight the dynamic processes of mass loss and stellar evolution, offering a glimpse into the pre-supernova phase of such cosmic giants.

First Detailed Image of Star Beyond Milky Way Captured

Astronomers have captured the first detailed image of a star outside the Milky Way, the red supergiant WOH G64, using the Very Large Telescope Interferometer. Located 160,000 light-years away in the Large Magellanic Cloud, WOH G64 is 2,000 times the size of the sun and is in its final stages before a supernova. The image reveals a cocoon of gas and dust surrounding the star, indicating significant material ejection. This achievement was made possible by the VLTI's GRAVITY instrument, which combines light from multiple telescopes for enhanced sensitivity.
