Cosmic rays are atom fragments that rain down on the Earth from outside of the solar system. They blaze at nearly the speed of light and have been blamed for electronic problems in satellites and other machinery. Discovered inmany things about cosmic rays remain a mystery more than a century later.

The sleeping cosmological giant woke up around years ago and devoured everything that came close to it, releasing intense amounts of radiation in the process. It began consuming as much nearby cosmic material it as it could and released radiation a million times stronger than it does today before going back to sleep. It is this light that is now being reflected by the galactic molecular clouds. Although black holes suck in and trap all light that enters their event horizons, the enormous forces they generate causes nearby matter to heat up to millions of degrees and results in the emission of radio waves and X-rays. The researchers say that the effect was so dramatic that it was comparable to a lone glow-worm buzzing around a forest at night suddenly becoming as bright as the Sun. Jason Goodyer.

Cosmic rays ionize nitrogen and oxygen molecules in the atmosphere, which leads to a number of chemical reactions.

But with large-scale experiments, scientists around the world are determined to find out. You may think the greatest, most perplexing mysteries of the universe exist way out there, at the edge of a black hole, or inside an exploding star. No, great mysteries of the universe surround us, all the time. They even permeate us, sailing straight through our bodies. One such mystery is cosmic rays, made of tiny bits of atoms.

About this rating. Rumors of dangerous cosmic rays passing by Earth "tonight," largely identical in their phrasing, have been steadily collecting in our inbox for well over a year. The warning, which has been around since at least , and whose timelessness is assured by the lack of specific dates or a discussion of time zones, is generally phrased as such:. Singapore TV announced on the news! Tonight pm to am for our Planet will be very high radiation! Cosmic rays will pass close to Earth, So please turn off your cell phone! Do not leave your device close to your body, it can cause you terrible damage! Send this message to all the people who matter to you! Thank you. Equally imprecise is the science involved in the warning.

With enough phones, Whiteson hopes, he and his colleagues can get a better picture of where cosmic rays come from. Archived from the original on 31 May The flux of incoming cosmic rays at the upper atmosphere is dependent on the solar wind , the Earth's magnetic field , and the energy of the cosmic rays.

Scientists have conclusive proof that many cosmic rays raining down on Earth come from distant exploded stars. Cosmic rays - mostly ultra-fast proton particles - would threaten life if not for the shielding of our planet's atmosphere and magnetic field. Nasa's Fermi telescope was used to study the very distinctive light that is produced when these protons crash into other particles in space.

The mystery of cosmic rays began with their discovery in Ernest Rutherford stated in that "thanks to the fine experiments of Professor Millikan and the even more far-reaching experiments of Professor Regener, we have now got for the first time, a curve of absorption of these radiations in water which we may safely rely upon". Main article: Health threat from cosmic rays. Most state-of-the-art EAS arrays employ plastic scintillators. Mainly from radioisotopes in food 40 K , 14 C, etc. ISBN No one knows where they come from. Most scientists suspect their origins are related to supernovas star explosions , but the challenge is that cosmic ray origins appeared uniform to observatories examining the entire sky for many years. Among the products of these star explosions are gamma-ray photons, which unlike cosmic rays are not affected by magnetic fields. Physical Review. With more work, however, scientists discovered that air can conduct electricity if its molecules are charged or ionized. Filed under: Science. According to Adrian Mellott and Mikhail Medvedev, million-year cycles in biological marine populations correlate with the motion of the Earth relative to the galactic plane and increases in exposure to cosmic rays. Retrieved 24 February Particles from the sun have stripped away most of Mars' atmosphere, resulting in very poor protection against radiation at the surface.
