When #NASAWebb observed the Horsehead Nebula in infrared light earlier this year, it took this sharp image of the top of the horse’s “mane,” a distinctive dust and gas structure.

The image is more than half-filled by a small section of the Horsehead Nebula, from the bottom up. The clouds are seen up close as thick, whitish streaks and dark voids, as well as textured, fuzzy-looking patterns of dust and gas. The nebula stops at a spiky edge that follows a slight curve. Above it a small number of distant stars and galaxies lie on a dark but multi-colored background.

The International Gemini Observatory’s twin telescopes can access the entire sky. The first two images are Gemini North in Hawaii and Gemini South in Chile. The third shows the Carina Nebula from Gemini South. Take a closer look: gemini.edu AURAPartners

A white domed building stands on the edge of a mountain at sunset. The sky is nearly covered in clouds that shine pink from the light of the setting sun. The horizon seen on the right side of the image is orange.
An observatory dome stands on a mountain top at night. Above it, curved white streaks appear in the dark sky. These are the trails of light from stars that were passing over as the photo was taken at a slow shutter speed.
A large gaseous cloud takes up the majority of this image, like a rocky mountain. The cloud is brown with shades of reddish-orange lining sections of it. Through the clouds, you can see a light blue haze. The image is covered in stars of all sizes.

The Tarantula Nebula is the brightest star-forming region in our galactic neighborhood and home to the hottest, most massive stars known. Its turbulent clouds of gas and dust have been observed by Hubble many times. Credit: NASA/ESA.

Wispy, nebulous clouds extend from the lower left. At the top and right, the dark background of space can be seen through the sparse nebula, a region of gas and dust set in shades of pink and red. Along the left and in the corner are many layers of bright pink gas and dark, deep red and dark gray obscuring dust. A cluster of small, bright blue stars in the same corner expands across the image. Many smaller stars cover the background.

You’ve been seeing a lot of amazing images of distant galaxies from the Webb Space Telescope lately. But let’s give a shoutout to the original deep field! In early 1996, astronomers unveiled Hubble’s view of a region of the sky that appeared empty to ground-based observatories. Within the image were hundreds of galaxies nearly four billion times fainter than the limits of human vision.

On a grainy black background, dozens of galaxies of various shapes, sizes, and colors are scattered. To the left of center, two blue spiral galaxies and one yellow spiral galaxy are particularly prominent. Only two stars are seen, one at top center and one just below and to the right of the yellow spiral. The stars both have four diffraction spikes.
