Astronomers caught one of the biggest stars in the galaxy dying

Scientists have got their hands on one of the most detailed images of a dying star, perhaps the largest in our galaxy – V Y Canis Majoris, according to a report independent,

to the unknown, VY Canis Majoris is a red hypergiant that can span the distance between our planet and the Sun’s diameter by about 10,000 times. However, not much is known about the death of such red hypergiants.,

Scientists believe that instead of flying over a large red region like most of this range, hypergiants are known to have evolved in irregular arcs and protrusions in a series of phases, releasing a considerable amount of mass. Is.,

However, recently, University of Arizona researchers managed to detect these protrusions, resulting in the clearest image ever captured of a hypergiant star.

This was done thanks to the Atacama Large Millimeter Array radio telescope in Chile, where astronomers detected specific molecules in matter ejected from the proud star.,

They then mapped these traces to images of the star previously taken by the Hubble Space Telescope to produce maps of sulfur oxide, silicon oxide, phosphorus oxide and sodium chloride in the material released by the star.

The image was first revealed on June 13 at the 240th meeting of the American Astronomical Society in Pasadena, California.

What makes this discovery even more special is that hypergiants are already rare in the Milky Way and we don’t know much about the second-brightest stars in the constellation Orion, Betelgeuse. and VY Canis Majoris, located about 3,000 light-years from our planet in the southern constellation Canis Major, however, is the largest of them all.

Lucy Ziuri, a chemistry professor at the University of Arizona, explained, “With these observations, we can now put them on maps in the sky. Until now, only a small part of this massive structure was studied, but you can see the larger scale.” But can’t understand the damage and how these massive stars die until you see the whole area. That’s why we wanted to make a complete image.”
