660BC.2019年在格陵兰岛,冰芯揭示了这次大约袭击地球的极端太阳风暴的新痕迹。 极端的太阳风暴也被称为“太阳能质子事件”,有时会在太阳耀斑等现象发生后用太阳的粒子轰击地球。
原文:660BC    In 2019 In Greenland, ice cores revealed new traces of an extreme solar storm that hit Earth about this time. Also called “solar proton events,” extreme solar storms occasionally bombard Earth with particles from the sun after phenomena such as solar flares. The storm that left the traces discovered by scientists likely temporarily degraded Earth’s ozone layer.
