Astronomers have confirmed that Betelgeuse has a hidden companion star, Siwarha, which creates a dense gas wake as it moves through the star's atmosphere, explaining long-standing variability and behavior changes in this red supergiant, with future observations planned for 2027.
The JWST has captured a massive red supergiant star just before it exploded in a supernova, providing new insights into how dust obscures these stars and potentially explaining why such supernovae are rarely observed. The star, in galaxy NGC 1637, was unusually red and dimmer due to dust, but JWST's infrared capabilities allowed detailed observation, suggesting previous supernovae might have been more luminous than thought.
Astronomers using the James Webb Space Telescope captured the first clear image of a star before and after it exploded as a supernova, revealing that the progenitor was a dust-enshrouded red supergiant, which helps explain why such stars are rarely observed before explosion. The discovery provides new insights into the final stages of massive stars and the role of dust in hiding their true nature.
The James Webb Space Telescope has captured the first detailed image of a red supergiant star before it exploded as a supernova, revealing that many such stars are hidden behind thick dust layers, which obscures them from optical telescopes. This discovery helps explain the previously observed scarcity of luminous red supergiants in pre-explosion images and provides new insights into the life cycle of massive stars.
A red supergiant star named DFK 52 has expelled the largest and most complex gas and dust cloud ever observed around such a star, likely involving multiple stars or a binary system, with significant implications for understanding stellar evolution and supernova precursors.
Astronomers have for the first time directly observed a close stellar companion to Betelgeuse using advanced imaging techniques, solving a long-standing mystery about its periodic brightness variations and revealing that Betelgeuse may eventually cannibalize this smaller star within the next 10,000 years.
Astronomers have captured the first close-up image of WOH G64, a massive red supergiant star located in the Large Magellanic Cloud, using the European Southern Observatory's Very Large Telescope Interferometer. This star, 1,500 times wider than the sun, is nearing the end of its life and may soon explode in a supernova. The image reveals an egg-shaped cocoon of gas and dust surrounding the star, which has dimmed significantly over the past decade. This discovery provides a rare opportunity to observe a star's life cycle in real time.
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.
Astronomers have captured the first-ever close-up image of a star outside the Milky Way, WOH G64, located in the Large Magellanic Cloud. Using the GRAVITY instrument on the European Southern Observatory's Very Large Telescope Interferometer, they observed a dusty cocoon around the star, indicating it is in the final stages before a supernova. This red supergiant, over 1,500 times the size of the sun, has shown significant changes over the past decade, providing a rare opportunity to study a star's life in real time.
Astronomers have captured the first close-up image of a star outside the Milky Way, WOH G64, using the GRAVITY instrument on ESO's Very Large Telescope Interferometer. Located in the Large Magellanic Cloud, this red supergiant is over 160,000 light-years away and is in the final stages before a supernova. The image reveals a dusty cocoon around the star, which has dimmed over the past decade, possibly due to material shedding or an undiscovered companion star. This observation offers a rare glimpse into the life cycle of distant stars.
Astronomers have captured the first close-up image of the red supergiant star WOH G64, located 160,000 light-years away in the Large Magellanic Cloud, as it nears the end of its life. Using the Very Large Telescope Interferometer, researchers observed the star shedding gas and dust, forming an egg-shaped cocoon, a precursor to a supernova explosion. This discovery offers a rare glimpse into the life cycle of massive stars, with WOH G64 being one of the largest known, potentially visible to the naked eye if it explodes.
Astronomers have captured the first close-up image of a dying star outside the Milky Way, WOH G64, located in the Large Magellanic Cloud, 160,000 light-years away. Using the ESO's Very Large Telescope Interferometer, they observed the red supergiant star's egg-shaped dust cocoon and potential torus, offering insights into its final stages before a supernova. This breakthrough in stellar observation highlights the star's dimming and structural changes, possibly due to material loss or another star's influence, marking a significant advancement in understanding stellar evolution.
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.
New simulations suggest that Betelgeuse's apparent rapid rotation may be an optical illusion caused by its "boiling" surface, rather than actual spinning. The red supergiant, which is nearing the end of its life, has been observed to spin at an unusually fast speed, but researchers now propose that this may be due to massive bubbles of gas rising and falling on its surface. Computer simulations show that these motions could be misinterpreted as spinning when observed through telescopes like ALMA. Further analysis of Betelgeuse's observations may confirm this theory and could also explain the rapid spins of other red supergiants.
