The fireballs are hot clumps of gas being ejected into space at speeds of over 100,000 mph.

Each one is about 30 times the mass of the Earth, according to Nasa scientists.

Star WR124: Live fast, die young (Nasa)

But the fiery blobs pose no threat to surrounding stars. As they cool, they will eventually dissipate into space.

The picture of the star known as WR124 taken by Hubble resembles an aerial fireworks explosion.

It is some 15,000 light years from Earth in the constellation of Sagittarius.

It is an extremely rare type known as a Wolf-Rayet star.

Such stars are expected to live fast and die young after going through a violent phase in which it spits out the fiery blobs.
