This is a bit terrifying. A sun is shooting cannonballs of plasma out into space in all directions and they are 2X the size of Mars. How many planets has this already destroyed and its going to continue for a long time. Lets just hope that we don't become its next target.

PASADENA, Calif., Oct. 6 (UPI) -- NASA's Hubble Space Telescope has captured images of large plasma 'cannonballs' being ejected from the vicinity of V Hydrae, a bloated red giant located 1,200 light-years from Earth.
Researchers believe the hurled blobs of plasma may explain the formation of planetary nebulae.
Hubble data suggests the cannonballs are roughly twice the size of Mars and travel at speeds fast enough to span the distance between Earth and the moon in just 30 minutes. A single blob is fired every 8.5 years. Astronomers estimate the stellar cannon has been firing plasma balls for at least 400 years.
Scientists can't quite fully explain the phenomena. The red giant from which the blobs appear to originate can't account for the ejected material. Instead, astronomers suggest an unseen companion star is the progenitor. (More at source).
