- Outflows contain an extraordinary amount of energy — about a million times that of an exploding star
- Believed to be caused by 'star power' from many generations of exploding stars
- Researchers say they pose no harm to Earth - but could be crucial to magnetic fields
- Seen from Earth, the outflows stretch about two-thirds across the sky from horizon to horizon
Mysterious 'monster' outflows of charged particles from the centre of our Galaxy, stretching more than halfway across the sky, have been detected by astronomers.
Researchers say they contain an 'extraordinary' amount of energy - but stress they pose no harm to us.
The researchers were able to map the cosmic 'geysers' of gas.
The giant cosmic geysers were..
