The story of the end of the world by the Mayans came and went without too much event but talks of apocalypse is always intriguing and perhaps frightening.

And there is yet another rumor of a flare causing the end of the world next May. The possibility came to life following an announcement from the National Aeronautics and Space Agency (NASA) saying that there could be problems to air flights and telecommunications next May because of irregular activities of the sun.

While most experts are projecting that the event will come and go without too much fanfare, there is evidence that the flare will be active when it comes.

The flare is expected to be more than just brilliant light from the sun. It will come to life and continue to glow.

Scientists say that the energy from the flare will be equivalent to the explosion of millions of atomic bombs, thus raising the rumor that it could cause an apocalypse. But it is not likely that it will be enough to swallow Earth.

But it will have a certain amount of impact on Earth. As part of the coronal mass ejection, the high-energy particles travelling at a speed of 2,000 kilimeters per hour will strike Earth in two to three days.



"2013년 5월 태양 폭발로 지구 멸망" 괴담

해프닝으로 끝나긴 했지만 21일 지구가 멸망할 것이라는 마야력을 근거로 한 괴담이 지구촌을 뒤숭숭하게 만들었다.

그런데 이번엔 '2013년 5월에 태양폭발(flare)이 최고조에 이르러 지구가 멸망한다'는 새로운 괴담이 떠돌고 있다. 얼마 전 미국항공우주국(NASA)이 '2013년은 태양활동 극대기로 비행기 운항과 통신 장애가 생길 수 있다'고 발표한 뒤 괴담이 확대 재생산되고 있다.

이도 큰일 없이 지나갈 것으로 보이지만 태양폭발이 왕성해지는 것은 다소 우려할 만한 일인 것은 분명하다.

이처럼 지구에 영향을 줄 천체의 변화를 알려주는 '우주 날씨 예보'가 활성화하고 있다. 지구 생명의 원천인 태양은 우리가 눈으로 보는 것처럼 항상 일정한 빛을 내는 항성이 아니다. 모닥불이 타오르듯 표면의 흑점에서 폭발이 발생하면서 끊임없이 활동하는 별이다.

과학자들은 태양폭발로 생기는 에너지의 양은 핵폭탄 수백만 개와 맞먹는 것이라고 분석한다. 그래서 폭발이 심해질 때 지구멸망설까지 나오는 것이다.

하지만 현재 생기는 태양폭발은 지구를 삼킬 정도로 위력적이지는 않다. 그렇다고 지구에 전혀 영향이 없는 것은 아니다. 태양폭발이 일어나면 태양에서 고에너지 입자들이 파편처럼 튀어나온다.

'코로나 물질 방출(CMEㆍCoronal Mass Ejection)' 혹은 '태양폭풍'이라는 현상이다. 이 고에너지 입자들은 초속 2,000㎞가 넘는 엄청난 속도로 우주를 뚫고 날아와 폭발 2, 3일 만에 지구에 도달한다.
