Scientists say comet 67p / churyumov gerasimenko has a far ultraviolet aurora that cannot be seen by the naked eye. Aurora was discovered by the Rosetta probe launched in 2004, which spent years chasing the comet in space. < / P > < p > as NASA explains in a new blog post, the discovery was made when researchers started studying images of comets and realized that the faint light that appears to come from behind a comet is actually produced by it. Aurora is not visible to the naked eye. It can only be seen with far ultraviolet detection technology, but it does exist. This is the first time that Aurora has been seen around an object other than a planet or moon. Scientists explain that Aurora is produced by the interaction between charged particles from the sun and the flow of matter from the comet itself. Particles react with molecules to produce this far ultraviolet light. < / P > < p > “the light around 67p / C-G is unique,” Marina galand, lead author of the study, said in a statement. “By connecting data from many Rosetta instruments, we can better understand what’s going on. This allows us to clearly determine how the atomic emission of 67p / C-G is formed. ” < / P > < p > “Rosetta is a constant gift,” Paul Feldman, co-author of the paper, said in a statement. “The data repository it sent back in two years of comet travel has allowed us to rewrite books about the strangest ‘inhabitants’ of the solar system – and in all respects, there’s more to come.” The report shows that the number of app store purchases soared in the first half of this year due to the impact of covid-19
