You can't see gamma rays with your eyes.They are much more energetic than the light that we can see.So you need a fancy detector to spot them.The Large High Altitude Air Shower Observatory (LHAASO)is an experiment in China.It searches for extremely high energy gamma rays. Scientists have spotted 12 gamma-ray hot spots.These are parts of the sky from which the gamma rays are sent out.Those hot spots show that our galaxy,the Milky Way,has powerful particle accelerators().But those particle accelerators aren't made by humans.Instead,they come from violent events in the universe.They might be exploding stars,for example.Such violent events make electric and magnetic fields,which can speed up protons ()and electrons.Those fast particles can then produce gamma rays with a lot of energy.That can happen when protons interact with other matter in space,for example Scientists aren't sure what could produce gamma rays with the extreme energies observed.But the new observations point to two possibilities.one hot spot was associated with the Crab Nebula.That's the remains of an exploded star.Another possible source was the Cygnus Cocoon.That's a region where massive stars are forming.The stars send out intense winds in the process. LHAASO is located on Haizi Mountain in China's Sichuan Province.It is not yet fully operational.It's due to be completed later this year.Then,it could find even more gamma rays. 语篇解读：本文是一篇说明文。文章主要介绍了近期天文学家发现了不知米自太空何 处的能量最蛋的伽马射线。 1.What can we learn about gamma rays? A.They are invisible. B.They are often ignored. C.They contain little energy. D.They are used to explore the universe. 解析：选A细节理解题。根据第二段中的“You can't see gamma rays with your eyes.” 可知，我们无法用肉眼看
