What Causes aurora?

                                   The Solar wind from the sun causes aurora. This aurora is formed because of the magnetic disturbances from the sun that are being exposed in the earths atmosphere. This aurora is seen in color's because of the ionization occurring in the upper layer of the earths atmosphere that is exosphere.

                                  Aurora emits radiation. And the earths ozone layer filters those radiations unharmed to living beings. These radiations not only affect the humans but also plants and animals and other living beings. The aurora emits radiation was being found in 1972. Even some radiations are being penetrated from ozone layer but being deflected by the magnetic field of the earth. So, these aurora don't cause any problems because of the protection by the nature.

                                   Aurora is not only formed on earth. The image that is being shown above is the aurora image of the Jupiter. Out of the solar system the Jupiter has the highest level of aurora because of containing of the highest amount of the electro magnetic field. There is no doubt that Jupiter is one if the four planets that emits X rays. The aurora is formed in the Jupiter is found with help of the Hubble telescope.
