 Spanning anywhere from 10,000 to 15,000 astronomical units (with 1 AU being the average distance between Earth and the sun) 

"It is much larger, much more massive and undergoes violent mass eruptions every 200 years or so."

Previous imaging of VY CMa with NASA's Hubble Space Telescope and spectroscopy showed the presence of distinct arcs and other clumps and knots
