Nicolaus Copernicus Poland Inducted in Nicolaus Copernicus was a Polish astronomer who put forth the theory that the Sun is at rest near the center of the Universe, and that the Earth, spinning on its axis once daily, revolves annually around the Sun. This is called the heliocentric, or Sun-centered, system.
Naked penguins with patches of bare skin have been popping up in the South Atlantic in recent years, puzzling scientists as to what could be causing a condition known as feather-loss disorder. New research has now documented the balding in chicks of African penguins Spheniscus demersus and Magellanic penguins Spheniscus magellanicus in captivity and in the wild, suggesting possible causes of the disorder, which can lead to slower growth and even death in some chicks. Boersma has conducted studies on Magellanic penguins for more than three decades.
Earth's magnetosphere protects us from solar radiation. Without it, the atmosphere would be destroyed. But when the magnetic polarity of the North and South poles swap, will we be left exposed?

The Sun sustains all life on our planet. As we frolic and bask under the warmth of its glow, little do we realize how it may one day have the power to destroy us as well. Death of the Sunproduced by the renowned Naked Science series, outlines the birth and potential demise of the most formidable star in our solar system.
Solar flares often are accompanied by explosions, called coronal mass ejectionsthat fling gargantuan quantities of energetic particles out into space. Earth can be bombarded by these CME particles, producing a storm in the magnetic bubble that surrounds the planet. The Sun reached a peak in this activity inalbeit a weak one. It was, in fact, the weakest maximum in solar activity since
