This artist’s impression of hypergiant star VY Canis Majoris shows the star’s vast convection cells and violent ejections. VY Canis Majoris is so large that if it replaced the Sun, the star would ...

Betelgeuse’s mysterious dimming across 2019 and 2020 was a big puzzle for astronomers. It turned out the cause was a mixture of the star's regular changes and the release of material that when cooling ...

New findings from NASA's Hubble Space Telescope have helped astronomers to solve the mystery of why Orion's bright red supergiant Betelgeuse dramatically faded for a period of weeks last year. In ...

In the southern hemisphere, in the constellation Canis Major, lies a very young, very massive red hypergiant star called VY Canis Majoris (VY CMa). A pulsating variable, its apparent magnitude (how ...

Scientists now possess the most detailed image yet of a dying giant: VY Canis Majoris, quite possibly the largest star in our galaxy. VY Canis Majoris is a red hypergiant, a class of star so massive ...

There are several candidates for the biggest star in the universe. One of them, VY Canis Majoris, is over 1,500 times the width of the sun. If it were placed in our solar system, it would stretch to ...

Our sun is huge compared to the Earth, capable of holding more than one million blue planets. The sun is small compared to some other stars in our galaxy, however. Stars like VY Canis Majoris, located ...

NASA researchers have published a new study that sheds light on the reason why the red supergiant VY Canis Majoris has grown dim, citing a phenomenon similar to the one that caused Betelgeuse to grow ...

A University of Arizona-led team of astronomers has created a detailed, three-dimensional image of a dying hypergiant star. The team, led by UArizona researchers Ambesh Singh and Lucy Ziurys, traced ...

The Milky Way's largest star is slowly dying, and all astronomers can do is watch. Of course, even if we could get to VY Canis Majoris, there isn't much we could do to stop the death of a star. In ...

Extreme supergiant stars known as hypergiants are very rare, with only a few known to exist in the Milky Way. By tracing molecular emissions in the outflows around the red hypergiant star VY Canis ...
