Large cluster of stars in the center of the image, surrounded by red dust and gas.
An approximately one-light-year-tall "pillar" of cold hydrogen towers above the wall of this molecular cloud in the Carina Nebula. The...
On the left is a wall of yellow, orange, and green gas and dust, with a dark pink/red finger-like structure of gas. The background for the right half of the image is hazy pink dust, with a star cluster of a few dozen stars glowing on the right.
This Hubble Space Telescope image of a dense swarm of stars shows the central region of the globular cluster NGC...
A cluster of stars. Most of the stars are very small and uniform in size, and they are notably yellowish and cluster more densely together toward the center of the image. Some appear larger in the foreground. The stars give way to a dark background at the corners.
This Hubble image shows off 2 million members of the biggest and brightest ball of stars in our galaxy. Caldwell...
A compact spherical cluster of so many stars that their light blurs together.
Like shiny flakes sparkling in a snow globe, over 100,000 stars whirl within the globular cluster M13, one of the...

White, red-orange, and a few blue stars packed tightly near the center in a sphere-shape, and thinning out farther from the center.
This image depicts bright, blue, newly formed stars that are blowing a cavity in the center of a star-forming region...
Blue-white clouds fill the scene. The top, right, and lower-right hold rusty-brown, dark clouds. These clouds billow out along the top and bottom of the image in an elongated backwards "C." Bright stars dot the scene.
This image captures two clusters full of massive stars that may be in the early stages of merging. The 30...

A cluster of stars fills the center of the image against a black background. A "U" of purple clouds rings the bottom and sides of the image, nesting the star cluster. A bright-red star is in the upper right corner.
This image features the star cluster Trumpler 14, one of the largest gatherings of massive, bright stars in the Milky...
Bright-white stars fill the center of the image. They are backlit by a blue cloud of gas and dust. Right side of the image holds a rusty-red cloud with dark dust lanes.
