“The origin of these high mass-loss episodes in both VY Canis Majoris and Betelgeuse is probably caused by large-scale surface activity, large convective cells like on the sun.

"In VY Canis Majoris -- 30 [times the] mass of [the] sun and 300,000 more luminous -- this is much more extreme," she said. "These gaseous outflows may be as much as 10 times the mass of Jupiter." ...

VY Canis Majoris is a pulsing variable star in the constellation Canis Major with a mass estimated to be 17 times that of the sun and a radius of 10,000 to 15,000 astronomical units (AU).

The red hypergiant star VY Canis Majoris, 4,000 light-years distant, is in a turbulent phase near the end of its life. Wracked by pulsations, it is expelling mass in a series of dusty knots and arcs.

But there are some discoveries that boggle the mind, and for me, VY Canis Majoris tops the list. Situated in the constellation Canis Major […] / Futurism / ...

Through observations of a red hypergiant known as VY Canis Majoris, astronomers have unraveled the mystery as to how stars shed vast quantities of mass before going supernova.

The red hypergiant star VY Canis Majoris (center, near dust cloud) is one of the largest known stars in the Milky Way. When spotted with a telescope in the night sky, it glows a vivid red. (Image ...

About 5,000 light years away across our Milky Way galaxy, a highly brilliant star called VY Canis Majoris has long been thought to be shrouded in smoke. Cornell and Harvard astronomers have found ...

Astronomers have discovered that the hypergiant star VY Canis Majoris is shedding 30 Earthloads of dust a year. ... VY Canis Majoris is around 30 to 40 times the mass of our Sun and 300,000 times ...

VY Canis Majoris is a stellar goliath, a red hypergiant, one of the largest known stars in the Milky Way. It is 30-40 times the mass of the Sun and 300,000 times more luminous.

As the core contracts under gravity, the outer layers expand, the star gets 100 times larger, and it begins to lose mass at a higher rate. VY Canis Majoris has probably already shed about half of ...
