description WOH G64 Overview
WOH G64 is a red supergiant star in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It lies in the constellation Dorado and is surrounded by a thick envelope of circumstellar dust, which affects how its light is observed. Astronomers study the star as an example of a massive, evolved star and as a case for understanding the late stages of red-supergiant evolution.
help WOH G64 FAQ
What kind of star is WOH G64?
WOH G64 is a red supergiant in the Large Magellanic Cloud, a satellite galaxy of the Milky Way. It lies in the constellation Dorado and is one of the most closely studied extreme red supergiants outside our galaxy.
Why does dust make WOH G64 difficult to observe?
WOH G64 is surrounded by a thick envelope of circumstellar dust that absorbs and scatters some of its light. That dust changes the star's apparent brightness and color and also provides clues about mass loss late in a massive star's life.
Was WOH G64 photographed in detail outside the Milky Way?
Yes, astronomers used the Very Large Telescope Interferometer to produce a detailed 2024 image of its dusty environment. The observation was notable because WOH G64 is located in the Large Magellanic Cloud rather than the Milky Way.
How is WOH G64 different from Betelgeuse?
Both WOH G64 and Betelgeuse are red supergiants, but WOH G64 is in the Large Magellanic Cloud while Betelgeuse is in the Milky Way. WOH G64 is also especially difficult to observe because of its unusually thick circumstellar dust.
