Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, [ 1 ] and from distant galaxies. [ 2 ] .

Cosmic rays are a form of high-energy radiation that originate from outside our solar system. When they reach Earth, the rays collide with particles in the upper atmosphere to produce a “shower” of particles, including muons. (Image: CERN)

2024年12月26日 · cosmic ray, a high-speed particle—either an atomic nucleus or an electron—that travels through space. Most of these particles come from sources within the Milky Way Galaxy and are known as galactic cosmic rays (GCRs).

Cosmic rays are particles from outer space that travel across the universe. They can be made by the sun, by other stars exploding, and even black holes. They move extremely fast, nearly the speed of light, but when they hit the Earth they are generally blocked by our atmosphere and made harmless to humans.

2023年6月19日 · Cosmic rays are atom fragments that rain down on the Earth from outside of the solar system. They blaze at nearly the speed of light and have been blamed for...

Cosmic ray astronomy is a branch of observational astronomy where scientists attempt to identify and study the potential sources of extremely high-energy (ranging from 1 MeV to more than 1 EeV) charged particles called cosmic rays coming from outer space.

宇宙線亦稱為宇宙射线（Cosmic ray）、宇宙輻射（Cosmic radiation），是來自外太空的帶電高能次原子粒子。它們可能會產生二次粒子穿透地球的大氣層和表面。射線這個名詞源自於曾被認為是電磁輻射的歷史。

宇宙線 亦稱為 宇宙射線 （Cosmic ray）、 宇宙輻射 （Cosmic radiation），是來自 外太空 的帶電高能 次原子粒子。 它們可能會產生二次粒子穿透地球的大氣層和表面。 射線 這個名詞源自於曾被認為是電磁輻射的歷史。 主要的初級宇宙射線（來自深太空與大氣層撞擊的粒子）成分在地球上一般都是穩定的 物質 的 粒子，像是 質子 、 原子核 或 電子。 但是，有非常少的比例是穩定的 反物質 的 反粒子，像是 反原子核 、 正電子 或 反質子，這剩餘的小部分是研究的活躍領域。 大 …

Cosmic Rays (CR) constitute a time and spatial variable flux of fully ionized energetic atoms and subatomic particles that continuously permeate the solar system, reaching the Earth with energies of approximately 10 6 to 10 21 electron-Volt (eV).

2017年9月6日 · Cosmic Rays. Cosmic rays provide one of our few direct samples of matter from outside the solar system. They are high energy particles that move through space at nearly the speed of light. Most cosmic rays are atomic nuclei stripped of their atoms with protons (hydrogen nuclei) being the most abundant type but nuclei of elements as
