Sunspot cycles, Space Weather and Earth [ A blog on the universe and the cosmos above and the nature of it determined by great scientists. ] Sunspot cycles are periodic cycles of the occurrence of sunspots on the sun's surface. On the other hand, Solar flares are a short period of sudden brightness in sunspot rich areas and space weather is overall affected by these phenomenon which further affects Earth Sunspots Solar Flares Space Weather Magnetic reversals Sunspots :                     Sunspots are typical dark spots that occur on the sun's light radiating outer surface. These sunspots often are observed to occur in pairs and define locations on the outer surface of the sun with relatively lower temperatures as compared to the surrounding areas. Though these areas define locations with lower surface temperatures, these sunspots are not permanent. They occur and vanish in a fixed time period. This time period is called as Solar Cycle / Sunspot Cycle . These Sunspot cyc

  Quasar and Blazars: dofference and facts (an illustrated guide) [ A blog on the universe and the cosmos above and the nature of it determined by great scientists. ] Quasars to be defined simply, are the jets of light emitted by supermassive black holes when they collide with each other. Radio Galaxies, Quasars and Blazars are the same phenomena observed from different angles      Black holes Binary Black Holes Active Galactic Nucleus [ AGN ] Quasars : Radio Galaxies, Blazars and Quasars Black Holes :  Black Holes: So Black holes aren't actually black colored holes in the universe. I have written a whole article on Black holes and what they are , so if interested then click here to check it out . But today in this blog I do will provide information about black holes                    So black holes are a stage in the evolution of a star. So yep, even stars evolve. I have written a blogpost on that topic too and this is the link to that page . So all the star start off by bein
