Various types of space rays detectable on Earth include radio waves, microwaves, infrared radiation, and visible light, while higher frequency infrared and gamma rays are blocked by the atmosphere. Neutrinos can pass through the atmosphere with minimal interaction, making them detectable. Cosmic rays primarily consist of protons and other particles, with few reaching the Earth's surface due to collisions in the atmosphere that create secondary cosmic rays. These secondary rays can be observed through air showers, although their original direction is often lost due to interactions with magnetic fields. Observatories on Earth and in orbit, like the Hubble telescope, help study these cosmic phenomena that are otherwise difficult to detect from the surface.
