Hello, World (photograph)

Hello, World is a photograph of Earth taken by NASA astronaut Reid Wiseman aboard the Orion spacecraft during the Artemis II mission, published April 3, 2026. The photo shows Earth as a disk, but not a complete hemisphere. It was captured during the first leg of the spacecraft's outbound journey toward the Moon. It and a preceding lower-exposure snapshot are the first photographs of a full Earth disk taken by a human since 1972, when The Blue Marble was taken by the Apollo 17 crew.

The image shows Earth at night illuminated by moonlight from a full Moon. Africa dominates the center of the frame, with the Sahara largely unobscured by cloud cover and parts of Europe visible to the north; the Iberian Peninsula appears at the lower left. The Atlantic Ocean is visible, with South America to the right. The Sun, Saturn, Neptune, Mars and Mercury are all hidden behind the Earth. The constellation Cetus appears to the right of Earth, the brightest star being Tau Ceti. Pegasus is in the lower left and Aquarius in the upper left. The photograph was taken on April 3, 2026, Wiseman captured the image through a spacecraft window using a Nikon D5 camera with a long exposure (, ISO 51,200, 1/4-second shutter speed). The Orion spacecraft was around 9,889 km (6,145 mi) from Earth's surface. NASA also released a lower-exposure "night" version of the image, taken shortly beforehand by Wiseman, which emphasizes city lights and reduces reflected glare. The title "Hello, World" alludes to the crew's greeting and to the traditional test message used in computer programming. ==See also==
