他們認為，太陽耀斑中的微小粒子（太陽的巨大能量爆發）比任何人之前認為的都要熱得多。

該大學的科學家在最新發表的研究中指出，太陽耀斑離子的溫度可高達 6,000 萬度。
Thatis 6.5 timeshotterthanpreviouslythought.
這比之前認為的溫度高出 6.5 倍。

太陽耀斑是一種電磁輻射，以光速從太陽傳播，只需八分鐘多一點就能到達地球。

基本上，它們是來自太陽大氣層的突然爆發的能量，向地球發出輻射。

這會增加到達地球的太陽X射線和輻射，對太空船和太空人造成危險，並影響地球的高層大氣。

新的研究表明，一些被稱為離子的粒子比其他粒子的溫度更高。

科學家亞歷山大·拉塞爾博士和他的團隊發現，一種稱為「磁重聯」的特殊過程使這些離子的加熱程度比其他粒子高得多。

這項新發現令人驚訝，因為人們過去認為耀斑中的所有粒子都具有相同的溫度。
Researchers from the University of St Andrews have made a new discovery.
They believe that tiny particles in solar flares—big bursts of energy on the Sun—are much hotter than anyone previously believed.
In their latest published research, scientists from the university argue that solar flare ions can reach temperatures up to 60 million degrees.
That is 6.5 times hotter than previously thought.
Solar flares are electromagnetic radiation that travel from the Sun at the speed of light, reaching Earth in just over eight minutes.
Basically, they are sudden bursts of energy from the Sun's atmosphere that send radiation towards Earth.
This can increase solar x-rays and radiation reaching Earth and are hazardous to spacecraft and astronauts, as well as affecting our planet's upper atmosphere.
The new study showed that some particles called ions, get even hotter than the others.
Scientist Dr. Alexander Russell and his team found out that a special process called 'magnetic reconnection' heat these ions much more than other particles.
This new discovery came as a surprise because people used to think all particles in the flare had the same temperature.
