| 41. | In the domain of Space Weather BIRA-IASB focuses on ionising space radiation and its effects.
|
| 42. | :I used to work in a laboratory that used de-ionised water in industrial quantities.
|
| 43. | Such " He II regions " are rare and indicate an extremely hot ionising star.
|
| 44. | Part of the nebula is ionised by the youngest ( bluest ) heavy stars in Pismis 24.
|
| 45. | A small electric voltage is applied to the ionised air which gives rise to a small electric current.
|
| 46. | The atom is not ionised, and the gamma ray continues on, although at a lower energy.
|
| 47. | Spectroscopic observations thus showed that planetary nebulae consisted largely of extremely rarefied ionised oxygen gas ( OIII ).
|
| 48. | This makes H II regions more complicated than planetary nebulae, which have only one central ionising source.
|
| 49. | The Homunculus Nebula is a small H II region, with gas shocked into ionised and excited states.
|
| 50. | A key design goal is that each original ionising event due to incident radiation produces only one avalanche.
