Controlled Impact Demonstration

On December 1, 1984, NASA and the Federal Aviation Administration (FAA) conducted the Controlled Impact Demonstration, where they deliberately crashed a Boeing 720 aircraft with the intent of improving occupant crash survivability. Seen left-to-right, top-to-bottom, the plane makes a practice approach, hits the ground, slides for a short distance, strikes posts cemented in the ground, and becomes engulfed in flames.

Seaweed farming in Indonesia

A farmer harvests seaweed growing on a rope, on the small island of Nusa Lembongan, Indonesia. Wooden posts demarcate the bay into rectangular plots that are owned by different families. Seaweed farming is a fairly simple process: Attached plants are placed in the sea and allowed to grow naturally, with little human intervention.

White-headed dwarf gecko with missing tail

A White-headed dwarf gecko (Lygodactylus picturatus) whose tail is missing due to autotomy, the act of an animal severing its own appendages, usually as a self-defense mechanism designed to elude a predator's grasp. The detached tail will continue to wriggle, distracting the predator's attention. The lost body part may be regenerated later.

Anscombe's quartet

Anscombe's quartet is a group of four data sets that have identical simple statistical properties, yet appear very different when graphed.

Satellite imagery of Africa

A composite satellite image of the geography of Africa, the Earth's second-largest continent, and its adjacent islands. Separated from Europe by the Mediterranean Sea and from much of Asia by the Red Sea, Africa is joined to Asia at its northeast extremity by the Isthmus of Suez. For geopolitical purposes, the Sinai Peninsula – east of the Suez Canal – is often considered part of Africa, although geographically it belongs in Asia. Africa can be divided into a number of geographic zones: The Atlas Mountains in the north, the Sahara, the coastal plains, and the inner plateaus.

The Garden of Earthly Delights

The right panel is a hellscape and portrays the torments of damnation. The intricacy of its symbolism, particularly that of the central panel, has led to a wide range of scholarly interpretations over the centuries.

Dirce Beauty butterfly

The Dirce Beauty (Colobura dirce) species of butterfly belongs to the Nymphalini tribe, the members of which are characterized by the jagged outline of their wings and the ability to survive the winter months as adults in an obligatory hibernal diapause, hiding in various shelters (e.g., crevices, hollows, cavities, even unheated buildings). The signature mark of all nymphalines is the cryptic color and spots on the underside of their wings, serving to conceal it against the surface on which it rests during hibernation.
