New Delhi Team Vishvas A post has been viral for some time on social media, which says that some cosmic rays will cross Earth from to tonight. The post advises people to keep their phones switched off during this time as it could be very harmful for the body. We found in our investigation that this claim is false.

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 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 in , many things about cosmic rays remain a mystery more than a century later. One prime example is exactly where they are coming 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. A significant leap forward in cosmic ray science came in when the Pierre Auger Observatory which is spread over 3, square kilometers, or 1, square miles, in western Argentina studied the arrival trajectories of 30, cosmic particles. It concluded that there is a difference in how frequently these cosmic rays arrive, depending on where you look. While their origins are still nebulous, knowing where to look is the first step in learning where they came from, the researchers said. The results were published in Science. Cosmic rays can even be used for applications outside of astronomy.

In his report on the experiment, Rossi wrote " Current experiments aim at more accurate measurements of the composition at high energies. When you go faster than the speed of sound, you produce a blast of noise.

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.

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. This allowed researchers to trace their source directly to ancient supernovas. Dr Funk himself has also presented it here in Boston at the annual meeting of the American Association for the Advancement of Science. Scientists have long suspected that many of the cosmic rays detected at Earth were accelerated in the colossal blasts that mark the demise of big stars, but the evidence has always carried some ambiguity.

National Geographic. Bibcode : PNAS There is strong evidence that some are produced in our own galaxy the Milky Way in supernova remnants the slowly decelerating aftermath of a star exploding, causing its material to plow through the surrounding space, which has low density but is not a completely empty vacuum. Particles with such crazy-high energies are thought to interact with the radiation leftover from the Big Bang and the creation of the universe, which ought to put the breaks on them before they reach us. Bibcode : ERL As the cosmic ray speed decreases due to deceleration in the stack, the ionization increases along the path. Clay and B. The outgoing shards of the atom are often energetic enough to in turn shatter additional atoms, and so on. Millikan believed that his measurements proved that the primary cosmic rays were gamma rays; i. The post advises people to keep their phones switched off during this time as it could be very harmful for the body. Proceedings of Science. The particles from that explosion then keep bursting apart other bits of matter, in a snowballing chain reaction.

Many, particularly at low energies, are produced by the sun. Archived from the original on 7 April Mars crash ends Nasa helicopter Ingenuity's mission. A fifth method, involving bubble chambers , can be used to detect cosmic ray particles. In , supernovae were said to have been "pinned down" as a source of cosmic rays, a discovery made by a group using data from the Very Large Telescope. No one knows where they come from. Homi J. Category:Astrochemistry Outer space portal Astronomy portal Chemistry portal. Primarily from radon, a depends on indoor accumulation of radon gas. Cosmic rays originate as primary cosmic rays, which are those originally produced in various astrophysical processes. Later experiments have helped to identify the sources of cosmic rays with greater certainty.
