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.

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 or astroparticles are high-energy particles or clusters of particles primarily represented by protons or atomic nuclei that move through space at nearly the speed of light. They originate from the Sun , from outside of the Solar System in our own galaxy, [1] and from distant galaxies. Cosmic rays were discovered by Victor Hess in in balloon experiments, for which he was awarded the Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. The term ray as in optical ray seems to have arisen from an initial belief, due to their penetrating power, that cosmic rays were mostly electromagnetic radiation. Meanwhile "cosmic" ray photons , which are quanta of electromagnetic radiation and so have no intrinsic mass are known by their common names, such as gamma rays or X-rays , depending on their photon energy. The precise nature of this remaining fraction is an area of active research. An active search from Earth orbit for anti-alpha particles has failed to detect them. Upon striking the atmosphere, cosmic rays violently burst atoms into other bits of matter, producing large amounts of pions and muons produced from the decay of charged pions , which have a short half-life as well as neutrinos. Of secondary cosmic rays, the charged pions produced by primary cosmic rays in the atmosphere swiftly decay, emitting muons. Unlike pions, these muons do not interact strongly with matter, and can travel through the atmosphere to penetrate even below ground level.

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.

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!

Quaternary Geochronology: Methods and Applications. On very clear, dark nights in the Utah desert, it can actually see the faint trails of cosmic rays lighting up in our atmosphere. Cosmic rays kept the level of carbon [85] in the atmosphere roughly constant 70 tons for at least the past , years, [ citation needed ] until the beginning of above-ground nuclear weapons testing in the early s. Stephenson, Detection of a galactic cosmic ray influence on clouds, Geophysical Research Abstracts, Vol. The detectors in Utah are made up of super-clear acrylic plastic, and are housed in units that kind of look like hospital beds. Pentagon UFO office finds 'no empirical evidence' for alien technology in new report. Cosmic rays are one type of ionizing radiation, meaning they are energetic enough to knock electrons out of atoms, ionizing them. University of Chicago Press. In the s, the term cosmic ray was coined by Robert Millikan who made measurements of ionization due to cosmic rays from deep under water to high altitudes and around the globe.

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.

Even Better How to make your anger work for you. That energy, Antonella Castellina, an Italian astrophysicist with the Pierre Auger Observatory , explains, is similar to a top tennis pro hitting a ball with all their strength. Retrieved 31 October During this time, he's walked the tunnels of the Large Hadron Collider, watched Stephen Hawking deliver his Reith Lecture on Black Holes and reported on everything from simulation universes to dancing cockatoos. They even permeate us, sailing straight through our bodies. Cosmic rays originate as primary cosmic rays, which are those originally produced in various astrophysical processes. By the combination of several detectors, some EAS arrays have the capability to distinguish muons from lighter secondary particles photons, electrons, positrons. Retrieved 16 April Ney in [] and by Robert E. Archived PDF from the original on 17 October Cosmic rays, therefore, contribute a small fraction of the total radiation dose people receive, smaller than that due to naturally occurring xenon from radioactive isotopes in Earth's crust, for example.
