Hubble Space Telescope has detected superhot blobs of gas, each twice as massive as the planet Mars, being ejected NEAR a dying star called V Hydrae, a red giant. The plasma balls are moving fast enough to travel the distance from Earth to the moon in thirty minutes. Astronomers estimate that this has continued once every 8.5 years for at least the past 400 years.
These fireballs are puzzling to astronomers, because the ejected material could not have been shot out by the host star, called V Hydrae.
From the article:
The current best explanation suggests the plasma balls were launched by an unseen companion star. According to this theory, the companion would have to be in an elliptical orbit that carries it close to the red giant's puffed-up atmosphere every 8.5 years. As the companion enters the bloated star's outer atmosphere, it gobbles up material. This material then settles into a disk around the companion, and serves as the launching pad for blobs of plasma, which travel at roughly a half-million miles per hour.
