The northern lights, or aurora borealis, offer an entrancing, dramatic, magical display that fascinates all who see it — but just what causes this dazzling natural phenomenon?
At the center of our solar system lies the sun, the yellow star that sustains life on our planet. The sun's many magnetic fields distort and twist as our parent star rotates on its axis. When these fields become knotted together, they burst and create so-called sunspots. Usually, these sunspots occur in pairs; the largest can be several times the size of Earth's diameter.
At the center of the sun, the temperature is 27 million degrees Fahrenheit (15 million degrees Celsius). As the temperature on its surface rises and falls, the sun boils and bubbles. Particles escape from the star from the sunspot regions on the surface, hurtling particles of plasma, known as solar wind, into space. It takes these winds around 40 hours to reach Earth. When they do, they can cause the dramatic displays known as the aurora borealis. [Infographics: How the Northern Lights Work & Anatomy of Sun Storms & Solar Flares]

What is breastfeeding?</h3>
The procedure through which a kid is fed human breast milk is known as breastfeeding or nursing. Breast milk may be directly from the mother's breast, expressed by hand, or pumped before being given to the child. Breastfeeding should start during the first hour of a newborn's life and should continue as frequently and as much as the baby desires, according to the World Health Organization (WHO).
The WHO and other health organizations advise exclusively breastfeeding for six months. This means that other than vitamin D, no other foods or beverages are normally supplied. WHO advises nursing exclusively during the first six months of life, then continuing with the addition of supplemental foods for the next two years and beyond.
