This artist's concepts shows a hypothesized event known as a superkilonova. A massive star explodes in a supernova (left), which generates elements like carbon and iron. In the aftermath, two neutron stars are born (middle), at least one of which is believed to be less massive than our Sun. The neutron stars spiral together, sending gravitational waves rippling through the cosmos, before merging in a dramatic kilonova (right). Kilonovae seed the universe with the heaviest elements, such as gold at platinum, which glow with red light.

An 1886 color illustration depicting a crowd of people, including men, women, and children, gathered around a massive wheel of cheese in the East Room of the White House. A man in a dark coat is carving into the cheese with a knife, while others eagerly reach out with their own knives and hands to take a piece. In the foreground, a small boy sits on the floor eating a piece of the cheese. This event commemorates the distribution of the "Mammoth Cheese" gifted to President Andrew Jackson in 1835.
