The red hypergiant VY Canis Majoris is much larger and more massive than the star Betelgeuse. The hypergiant began to fade
New data from NASA's Hubble Space Telescope suggests that the same processes occur in this hypergiant as at Betelgeuse, but on a large scale.
The Betelgeuse eclipse was associated with a gasa stream that may have formed dust that obscured part of Betelgeuse's light. A similar thing happened with VY Canis Majoris, but on a much larger scale. Massive ejections of matter, which caused the fading, temporarily blocked the light from the star.
Giant arcs of plasma surround the star ona distance thousands of times greater than the distance from the Earth to the Sun. These arcs are similar to the solar prominences of our own Sun, only on a much larger scale. In addition, they are not physically associated with the star, but rather were thrown away and are now moving in the opposite direction from the star.
In a new work, the authors found out that theseeruptions of plasma arcs occurred around the 19th and 20th centuries, when VY Canis Majoris sharply dimmed. Now, during the next tarnishing, VY Canis Majoris may be in a unique evolutionary state, the authors suggest.
Due to these emissions, VY Canis Majoris may havehas already lost half of its mass. Instead of exploding like a supernova, the star could simply collapse right into a black hole. The authors of the work stated that observations of the celestial body continue.
Physicists have created an analogue of a black hole and confirmed Hawking's theory. Where it leads?
