Eta Carinae, the most luminous and massive stellar system within 10,000 light-years, is accelerating particles to high energies, some of which may reach Earth as cosmic rays, a study using data from a NASA telescope has found.

"We know the blast waves of exploded stars can accelerate cosmic ray particles to speeds comparable to that of light, an incredible energy boost," said Kenji Hamaguchi, an astrophysicist at NASA's Goddard Space Flight Center in the US.

"Similar processes must occur in other extreme environments. Our analysis indicates Eta Carinae is one of them," said Hamaguchi, lead author of the study published in the journal Nature Astronomy.
Astronomers know that cosmic rays with energies greater than one billion electron volts (eV) come to us from beyond our solar system. However, because these particles: electrons, protons, and atomic nuclei, all carry an electrical charge, they veer off course whenever they encounter magnetic fields. This scrambles their paths and masks their origins.

Eta Carinae, located about 7,500 light-years away in the southern constellation of Carina, is famous for a 19th century outburst that briefly made it the second-brightest star in the sky.
