“Fireball” Star Puzzles Scientists

“Fireball” Star Puzzles Scientists
A red giant star, V Hydrae 1200 lightyears from Earth, has been detected shooting giant plasma balls roughly twice the size of Mars into space. Scientists estimate that this has been happening annually every 8.5 years for at least the last 400 years or so and puzzles scientists because bloated red giants like V Hydrae shouldn’t be behaving in this manner. This has led to speculation that there is a secondary star orbiting V Hydrae causing the ejections.
