cosmic rays
1. Nuclear and subatomic particles moving through space at high speeds; radiated from the sun and other stars.
2. Streams of ionizing radiations from space, largely of protons, alpha particles, and other atomic nuclei.
3. Very high energy nuclei moving at velocities close to that of light which are probably produced by supernova explosions.

On striking the earth's atmosphere, they produce cascades of other particles (by collision with nuclei in the atmosphere) called air showers.

X-rays, X rays
In astronomy, any of a class of cosmic objects that emit radiation at X-ray wavelength.

Because the earth’s atmosphere absorbs X-rays very efficiently, X-ray telescopes and detectors must be carried high above it by spacecraft to observe objects that produce such electromagnetic radiation.

Advances in instrumentation and improved observational techniques have led to the discovery of an increasing number of X-ray sources.

By the late 20th century, thousands of these objects had been detected throughout the universe.
