NASA | What Are Gamma Rays?
Ғылым және технология
What we call "light" is actually just a tiny fraction of the broad range of radiation on the electromagnetic radiation spectrum. The entire span stretches from very-low-energy radio waves through microwaves, infrared light, visible light, ultraviolet light, X rays, and finally to very-high-energy gamma rays. The processes producing photons (single particles of electromagnetic radiation) of each type of radiation differ, as do their energy, but all of the different forms of radiation are still just part of the electromagnetic spectrum's family. The only real difference between a gamma-ray photon and a visible-light photon is the energy. Gamma rays can have over a billion times the energy of the type of light visible to our eyes. They are produced by the hottest and most energetic objects in the universe, such as neutron stars and pulsars, supernova explosions, and regions around black holes. On Earth, gamma rays are generated by nuclear explosions, lightning, and the less dramatic activity of radioactive decay.
In fact, gamma rays are so energetic that they are harmful to life on Earth. Luckily, Earth's atmosphere absorbs gamma rays, preventing them from affecting life on the ground. But this poses a problem if you want to observe the Universe in gamma-ray light. The very atmosphere that protects us from gamma rays prevents us from directly observing them from the ground. Astronomical observations of gamma-ray sources are therefore done with high-altitude balloons or satellites, above the protective blanket of Earth's atmosphere.
The high energy of gamma rays poses another problem: they can pass right through any lens or mirror, making it very difficult to focus them in a telescope. Astronomical observations, therefore, must rely on a different technology to view the gamma-ray universe. Scientists must make use of methods developed by particle physicists, who have long understood techniques for measuring high-energy particles. The Fermi Gamma-ray Space Telescope's specialized astronomical instruments employ detectors used and perfected by physicists interested in the interactions of subatomic particles.

Deep Gama Ray bursts,those that seem to come from nowhere,those that come from beyond 45billion light years (the max dist we can see vis light) are a wonder.

I've just discovered that Alien ships leave tell tale signs of exiting space jump and entering an orbit through bursts of gamma rays which are highly detectable.
good vid man
@NASAexplorer I noticed among your speakers explaining Gamma Rays that you neglected the formost authority on Gamma Rays: Bruce Banner.
Hulk will smash...
How did I just write 3 paragraphs about Gamma rays on a 1 minute and 39 second video?! 😂
Where can I watch the WHOLE video!! Please! info!
I have a doubt pls clear it. I studied that gama rays are not constitute of particle so how they travel.Are they disturbance??or what I am confused pls help.
what frequency were you using for exposure? or did you use an oscillating pulse freq inside a tesla coil configure or did you just grow near a radio playing rap music and the plants died prematurely... i can empathize.
wait... wouldn't the gamma rays over probably septillions of light years turn into visible light due to redshift?
if we can mix gama rays to automatic repulse created than what will happen sir?

So this is how Dr. Banner became what he is now.
the visual of the EM spectrum at 0:28 is wrong: it doesn't go from infrared to violet, blue, green, yellow, orange, red, and then back through orange, yellow, green, blue, violet and then to ultraviolet....does it? it goes from infrared to red, then orange, yellow, green, blue, violet and on to ultraviolet. right?
What would happen to astronauts if they were suddenly get too close on a gamma ray explosion when protected in their space craft from the heat the massive blast generates?

They will literally die
And do they redshift too?
What about dark lightning?
...and yet the biggest explosions in the universe of magnitudes the average mind is unable to comprehend, go mainly unnoticed.
I love you guys you are amazing when I was reading about quasars I read that they emits gama radiation and at that time I didn't know what is gama radiation but after watching this video my doubt is clear regarding this topic Thanks guys 😊

What is higher than gamma rays?
if light is reflected from a object to make it visible then gamma radiation isn’t being absorbed by lead it’s just being reflected backwards 😧
What is beyond Gamma Rays? There has to be higher frequencies.
Can gamma rays be absorbed by black holes

Is it possible to convert one form of energy in the spectrum to another form, for instance, is there a way of converting ultra violet light to x-rays?

+Amalinze DeCat I don't know if people can that but I can tell you that stars do this. Star produce their energy via nuclear fusion during which they produce a gamma photons, the photons are continually absorbed and reemitted during which they lose some energy. When they reach the surface of a star some of the gamma photons lose enough to become visible light which we see as sunlight here on earth.

Are these the same or similar powerful game rays coming into my house and body, from untrapped bass music speakers at my neighbor’s? They sure are and feel intrusive! What could possibly be the scientific and medical benefit of my regularly being exposed to these rays or frequencies?

You could but it is impossible to stop the gamma rays once you have emitted them from the source, same as high intensity heat. There are people working on ways to stop energy sources instantly In one location for this and other purposes.
