| 21. | This conclusion was confirmed in 1974 when the unmanned " Mariner 10 " spaceprobe discovered only a tenuous exosphere.
|
| 22. | Later, in 2008, improved measurements were obtained by the MESSENGER spacecraft, which discovered magnesium in the Mercurian exosphere.
|
| 23. | The atmosphere of Jupiter is classified into four layers, by increasing altitude : the troposphere, stratosphere, thermosphere and exosphere.
|
| 24. | "' Exosphere "'( foaled 25 August 2012 ) is a Thoroughbred racehorse trained and bred in Australia.
|
| 25. | On 14 February 2015, Exosphere won his first race, leading by 4 lengths in the 1000m race at Kembla Grange.
|
| 26. | Measurements of Mercury's exosphere, which is practically a vacuum, revealed more ions derived from water than scientists had expected.
|
| 27. | The thermosphere and exosphere begin at around 95 kilometres, eventually reaching the limit of the atmosphere at about 220 to 250 km.
|
| 28. | Two weeks later, Exosphere was " dominant " in the Golden Rose, winning his first Group 1 event by 2 lengths.
|
| 29. | Smaller bodies such as asteroids, in which the molecules emitted from the surface escape to space, are not considered to have exospheres.
|
| 30. | However, the aurora borealis and aurora australis sometimes occur in the lower part of the exosphere, where they overlap into the thermosphere.
