Aurelia aurita, popularly known as the moon jellyfish, is a widely studied species of the genusAurelia. It is translucent, usually about 25–40 cm (10–16 in) in diameter, and can be recognized by its four horseshoe-shaped gonads, easily seen through the top of the bell. It feeds by collecting medusae, plankton, and mollusks with its tentacles, and bringing them into its body for digestion. Capable of only limited motion, it drifts with the current, even when swimming.Photograph: Alexander Vasenin
A diagram of a supercell in the Northern Hemisphere, showing the different parts of its structure. Supercells are thunderstorms characterized by the presence of a mesocyclone: a deep, persistently rotating updraft. Of the four types of thunderstorms (supercell, squall line, multi-cell, and single-cell), supercells are the least common and have the potential to be the most severe. Supercells are often isolated from other thunderstorms and can dominate the local weather up to 30 kilometres (20 mi) away.Diagram: Kelvin Ma

Jesse B. Jackson was a United States consul and an eyewitness to the Armenian Genocide. He served as consul in Aleppo when the town was the junction of many important deportation routes. Jackson concluded that the policies towards the Armenians were carefully planned to "extinguish the Armenian race". He estimated that a million Armenians had been killed and considered his own survival a "miracle". After the genocide, Jackson led a relief effort and was credited with saving the lives of thousands.Photograph: Harris & Ewing; restoration: Centpacrr
