What happens when a cosmic ray hits an atom?

When the particles in cosmic rays collide with the atoms in at the top of the atmosphere, they burst, tearing apart atoms in a violent collision. The particles from that explosion then keep bursting apart other bits of matter, in a snowballing chain reaction. Some of this atomic shrapnel even hits the ground.

How much radiation is in interstellar space?

For comparison, a radiation dose obtained in a non-relativistic space module moving in interstellar space would be, approximately, 70 rems/year [6] whilst the safety level for a person is between 5 – 10 rems/year. The dose will, most likely, increase when accelerating to relativistic velocities.

How do cosmic rays make muons?

Muons are everywhere Muons have the same negative charge as electrons but 200 times the mass. They are made when high-energy particles called cosmic rays slam into atoms in Earth’s atmosphere. Travelling at close to the speed of light, muons shower Earth from all angles.

How far do cosmic rays penetrate the earth?

Some secondary muons have such high energies that they are able to penetrate the Earth to depths of more than 3.2 km (2 miles). To study primary cosmic rays directly, high-altitude balloons (typically reaching altitudes of 37 km [about 120,000 feet]) have been extensively used.

What has Voyager 1 discovered in interstellar space?

Four and a half decades after launch and over 14 billion miles from Earth, Voyager 1 still makes new discoveries. The spacecraft has picked up the signature of interstellar space itself, a faint plasma “hum” scientists compared to gentle rain.

What are cosmic rays and how do they work?

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 heavy as lead have been measured.

Can cosmic rays be deflected by magnetic fields?

Since cosmic rays are charged – positively charged protons or nuclei, or negatively charged electrons – their paths through space can be deflected by magnetic fields (except for the highest energy cosmic rays).

Can we send humans to the edge of interstellar space?

An error occurred while retrieving sharing information. Please try again later. NASA’s Voyager 1 and Voyager 2 probes are both in interstellar space. For the moment, sending humans to the edge of interstellar space, let alone across the cosmic void to other stars, remains firmly in the realm of science fiction.

Could the Sun be used as a lens for interstellar space?

The solar gravity lens marks the point where a conceptual spacecraft in interstellar space could use our Sun as a gigantic lens, allowing zoomed-in close-ups of planets orbiting other stars. Credits: Charles Carter/Keck Institute for Space Studies 1. The Space Between
