Euclid also imaged the Horsehead Nebula, part of the constellation Orion, located a mere 1,375 light-years away. The nebula is the closest giant star-forming region to Earth, according to an ESA release, and Euclid’s image was taken in just an hour.

The nebula is illuminated with ultraviolet radiation from the nearby star Sigma Orionis. The star is not in this image, as it would outshine all the detail of the nebula’s gas and the background stars.
