Look how tiny JWST's view of the sky is, especially compared to Euclid's wide field of view.

#JWST took an image of the very top of the Horsehead Nebula, focusing in on a region that transitions from a dense, warm area of gas and dust (blue) to an area of hot, ionized gas (red).

A horizontal collage of three images of the Horsehead Nebula. The left image is labeled “Euclid (Visible-Infrared)” and shows a dusty red-brown nebula at bottom with wispy blue clouds in the middle and the black background of space at top, with stars throughout. A portion of the nebula shaped like the head of a seahorse juts upward from the thickest part of the nebula into the blue wisps. A small box around it connects to the second image labeled “Hubble (Infrared)”, where the Nebula is zoomed in on. Here the central part of the horse’s head remains a dark, dusty red, while the outer portions become a translucent, ethereal gray. At the top of the horse’s head, a box connects to the third image labeled “Webb (Infrared)”. A clumpy dome of blueish-gray clouds rises about a third of the way into the image, capped with translucent red wisps and, at top, a single, prominent star.
