Unsolved Mystery: Where Do These X-Rays Come From?

In summary, the source of X-rays in space has been a topic of debate, but a recent study confirms that some of these X-rays come from particles converted into photons in Earth's magnetic field. However, there is still a mystery surrounding another group of X-rays with no known source. This phenomenon is similar to neutrino oscillations, where particles can change in a magnetic field. This information is discussed in the A level physics textbook, OCR A Level Physics A 2015: Student book 2.

Has anyone an idea where these X rays come from?

https://www.sciencedaily.com/releases/2016/09/160926104700.htm

From Science daily,

Space is filled with types of light we can't see -- from infrared signals released by hot stars and galaxies, to the cosmic microwave background. Some of this invisible light that fills space takes the form of X-rays, the source of which has been hotly contended over the past few decades. A new study confirms some ideas about where these X-rays come from, shedding light on our solar neighborhood's early history. But it also reveals a new mystery -- an entire group of X-rays that don't come from any known source.

I have heard about some particles which can change to photons in a magnetic field such as the Earth's magnetic field. For example the particles axioms are theoretical particles that are produced by stars and supernova and when our sun produces them they are converted into X-ray photons in the Earth's magnetic field.

do you have a reliable source for that please ?

I read about this theoretical phenomenon in my A level physics textbook, OCR A Level Physics A 2015: Student book 2 (OCR GCE Science 2015).

I would hazard to guess the origin of x ray photons in a magnetic field as an example of a mixed state, similar to the phenomenon of neutrino oscillations as discussed here https://profmattstrassler.com/artic...nos/neutrino-types-and-neutrino-oscillations/. Passage through a magnetic field sometimes alters certain particles at certain energy levels and production of x ray photons are one of the consequences.
 

1. Where do X-rays come from?

X-rays are a form of electromagnetic radiation, which means they are a type of energy that travels in waves. They are created when high-speed electrons collide with atoms, causing them to emit energy in the form of X-rays. This can happen in a variety of settings, such as in outer space or in a medical X-ray machine.

2. How were X-rays discovered?

X-rays were discovered in 1895 by German physicist Wilhelm Roentgen. While experimenting with cathode ray tubes, he noticed that a fluorescent screen near the tubes would light up when the tubes were turned on. He realized that this was caused by a new type of radiation that could pass through objects and produce images on photographic plates.

3. What are the uses of X-rays?

X-rays have a wide range of uses in various fields, including medicine, security, and industry. In medicine, X-rays are commonly used for diagnostic imaging to see the internal structures of the body. In security, X-rays are used for scanning luggage and packages at airports. In industry, X-rays are used for inspecting materials and products for defects.

4. Are X-rays harmful?

X-rays can be harmful if a person is exposed to them in large doses or for extended periods of time. Their high energy can damage cells and DNA, potentially leading to health issues such as cancer. However, the amount of radiation used in medical X-rays is very low and considered safe. Proper shielding and safety protocols are also in place to minimize the risk of harm.

5. Can X-rays be blocked?

Yes, X-rays can be blocked by certain materials, such as lead and concrete. This is why doctors and technicians wear lead aprons when taking X-rays and why X-ray rooms are lined with lead. However, X-rays can also pass through soft tissues and some materials, which is what allows them to create images of the internal structures of the body.
