This image covers a very large expanse of sky, containing the seven most easily recognisable stars of the constellation Orion, including the giants Betelgeuse (red supergiant, lower left) and Rigel (blue supergiant, upper right). From our vantage point on the Earth's surface, this image covers the same apparent size as about 40x30 Moons aligned on each of their axes and we can distinguish well-known astronomical objects such as the "Horse's Head" or the nearest star-forming region visible to the naked eye, M42. But, on a larger scale, it is even more striking. Supernova remnants stain the entire image red, expanding and braiding clouds of matter across the image of this large region of the sky. 

Mosaic of 3x5 images obtained with the STC Astograph of the IAC's UC3. 

The Unit of Communication and Scientific Culture (UC3) of the Instituto de Astrofísica de Canarias (IAC) in collaboration with the Museum of Science and the Cosmos (Museums of Tenerife) has edited an astronomical wall calendar, with astronomical ephemerides for the year 2022, which can be consulted and downloaded in digital form and can be obtained in physical form at the IAC Headquarters in La Laguna. The 12 astronomical images which illustrate it have been obtained by astrophotographer Daniel López (The Canary Sky) and the astrophysicists Alfred Rosenberg (IAC), Oswaldo González (MCC, Museums of Tenerife) and Sebastián Hidalgo (IAC). As well as this calendar there is also a calendar in poster format, with the image of the Veil Nebula.
