Astronomers monitoring the red supergiant WOH G64 in the Large Magellanic Cloud report a rapid evolution into a yellow hypergiant, with a temperature rise of about 1,000 C and significant shrinking. This rare color and size change may signal an impending supernova, though researchers offer two possible explanations—binary interaction with a companion or a prior eruptive episode—and the star’s exact fate remains uncertain.
Astronomers say WOH G64, a red supergiant in the Large Magellanic Cloud about 165,000 light-years away and roughly 30 solar masses with a radius over 1,500 suns, is likely transitioning toward a yellow hypergiant after shedding outer layers; this may lead to a spectacular end in a supernova or direct collapse into a black hole, with the fate expected to unfold over hundreds to thousands of years in cosmic time.
Astronomers tracking the star WOH G64 in the Large Magellanic Cloud have observed it change from a red supergiant into a rare yellow hypergiant, a dramatic and unusually slow transformation that could mark the star’s evolution toward a core-collapse supernova or direct black-hole formation. The object, about 28 solar masses and roughly 1,540 times the Sun’s size, may be part of a binary system, with interactions potentially influencing its path to death. While this hints at a possible explosive finale, the final fate remains uncertain and would likely occur on timescales of hundreds to thousands of years rather than within our lifetime; the findings were reported in Nature.
New research finds that WOH G64, one of the universe’s largest stars in the Large Magellanic Cloud, shifted from a red supergiant to a yellow hypergiant around 2014, likely shedding mass as its core contracts and heats. If confirmed, this rapid evolution could herald an imminent supernova, offering a rare chance to observe a star dying in real time.
New observations of WOH G64 question earlier claims it briefly became a yellow hypergiant; latest spectra indicate it remains a red supergiant with a hot binary companion, implying observed changes may arise from atmospheric/binary effects rather than imminent supernova, so continued monitoring is essential.
New SALT spectroscopy of the star WOH G64 in the Large Magellanic Cloud shows it is still a red supergiant, not dying to become a yellow hypergiant as previously thought. Titanium oxide in its atmosphere contradicts earlier interpretations based on dimming and dust, and a possible close companion could be distorting the star’s atmosphere and cocoon, reshaping ideas about its evolution.
Astronomers reinterpreted the puzzling behavior of the red supergiant WOH G64 in the Large Magellanic Cloud, finding it is not rapidly dying but part of a binary system with a hotter, smaller companion that interacts with the red star’s extended atmosphere. New optical spectra from SALT show strong titanium oxide bands indicating a cool atmosphere, contradicting claims it was turning into a yellow hypergiant. The strange emissions and the recent dust cloud are explained by material being pulled from the red giant and forming structures around the companion, not by an imminent collapse. The result is a dramatic reminder that binary interactions can mimic signs of stellar death while the star’s evolution continues, with a future supernova still possible but not imminent.
Astronomers have captured the first close-up image of a star outside our Galaxy, WOH G64, located 160,000 lightyears away in the Large Magellanic Cloud. This red supergiant, imaged using the ESO's Very Large Telescope Interferometer, is in its final life stages, shedding gas and dust before a potential supernova. The discovery offers a rare opportunity to observe a star's life cycle in real time, revealing a dimming and an egg-shaped cocoon around the star, possibly due to material ejection or an unseen companion 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.
