Thanks to an extraordinary technological innovation, it has been possible to capture WOH G64, a red supergiant located in the Large Magellanic Cloud, 160,000 light years from Earth. This exceptional result was achieved by Andrés Bello University in collaboration with ESO's Very Large Telescope Interferometer (VLTI) in the Atacama Desert, Chile.
An unprecedented stellar foreground
The star, long known to astronomers, is in the final stages of its life. The image shows an elongated shell of gas and dust, typical of red supergiants about to become supernovae. With the help of the VLTI's second-generation instruments, researchers have captured details never seen before, revealing that WOH G64 is fading faster and faster.
Technology for the future of space exploration
The VLTI combines the light from four Very Large Telescope telescopes, creating a “virtual telescope” capable of obtaining super-detailed images. However, taking new close-up photos of WOH G64 will become increasingly difficult as the star loses brightness. Hopes are pinned on future upgrades to the instrumentation.
