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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
WASHINGTON, D.C. — About 5,000 light years away across our Milky Way galaxy, a highly brilliant star called VY Canis Majoris has long been thought to have smoke in its eyes because most of its light ...
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 ...
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 ...
