Do you know what is aurora? Aurora sometimes referred to as polar lights, northern lights (aurora borealis), southern lights (aurora australis), is a natural light display in the Earth's sky, predominantly seen in the high-latitude regions (around the Arctic and Antarctic). Auroras are the result of disturbances in the magnetosphere caused by solar wind. These disturbances are regularly strong enough to alter the trajectories of charged particles in both solar wind and magnetospheric plasma. These particles, mainly electrons and protons, precipitate into the upper atmosphere (thermosphere/exosphere). The resulting ionization and excitation of atmospheric constituents emits light of varying color and complexity. The form of the aurora, occurring within bands around both polar regions, is also dependent on the amount of acceleration imparted to the precipitating particles. Precipitating protons generally produce optical emissions as incident hydrogen atoms after gaining electrons f
Aspiration is hope or ambition of achieving something for a better future. As a young generation, we must have the courage to express our aspiration because we have the power to change our society to a better; worthwhile ones. In conveying aspirations, we need to know what is our goal. Miss Keri Lestari said that we need to know for whom we deliver our aspirations. For instance: if we don't feel comfortable of the facilities in our school, then we need to know the person who is responsible for the facilities in school; we can convey our aspirations in this aspect to the vice principal of the infrastructure sector (Bu Yattini). Then our aspirations must based on fact and data, we must not give any aspiration that only based by our own will that is not useful for the society. An aspiration must be considered well by an individual, therefore the aspiration can change many cases into a better situation in the future. We also need to deliver our aspiration by a good manner so that
