The top image shows an opaque column of gold and brown glowing gas and dust rising against a blue-green background of gas-filled space with scattered pinkish stars. The bottom image shows the same image, but many more stars are visible. The column of gas and dust is a dim, ghostly gray version of itself and mostly transparent. Stars can be seen through it and a cloudy jet of gas is visible emerging horizontally from within the column. The background is black space dotted with a myriad of stars.

On the bottom is an image of a compact spherical cluster of white stars, so thickly assembled near its center that it becomes imposssible to distinguish between them. A small box in that calls out the next image, to the right, a Hubble closeup of some of the stars that shows many white and blue stars against a black bacgkground. Another callout box in that shows a closeup of stars in the Hubble image. This image, to the top left, shows multiple bluish and reddish stars.

A series of 5 images in blocks that "zoom in" until they end in the Hubble image of Caldwell 94. They start with an image of distant gas, dust and stars and each exhibits progressively more detail until the Hubble image displays large, individual white and reddish stars.

Hubble’s Advanced Camera for Surveys (ACS) captured the image in the upper right, showing stars in Caldwell 96 (NGC 2516),...
To the left is a cluster of blue stars against a black background. Two bright orange stars are near the top of the image. A callout box at the edge of the cluster shows the location of the Hubble image (shown at the right), which features scattered stars including several large bright ones.
The image in the upper right, taken with a single infrared filter by Hubble’s Wide Field Camera 3 (WFC3), shows...
A cluster of blue stars with two bright yellow stars near the top of the image is to the left. A callout box on a section of that image points to a larger image at the right of several very bright large stars.
This stunning image captures a small region on the edge of the inky Coalsack Nebula, or Caldwell 99. Caldwell 99...
A handful of bright stars amidst and around a blue misty blob of glowing gas.
Caldwell 100 (also called Collinder 249) is a loose collection of stars, known as an open cluster, that’s embedded within...
A rusty-orange background is dotted with dark clouds. One large, dark cloud at upper right, two medium-sized dark clouds at the bottom; one left, the other right, of center. The upper left corner is blacked-out in a step pattern.
Caldwell 101 has a spiral shape. It stretches far beyond the edges of this Hubble view, more than 200,000 light-years...
A large spiral galaxy fills the frame. A bright core of stars, just left of center. Dust-filled spiral arms wrap around toward the top, right, and bottom of the image.
30 Doradus is the brightest star-forming region in our galactic neighbourhood and home to the most massive stars ever seen....
Tones of rusty-brown, blue, white, and a smattering of red fill the scene. Left of center holds bright-white tendrils of gas and a star cluster. Surrounding the cluster are tendrils and clumps of rusty-brown gas. Upper-left background glows faintly dark blue, while the lower half of the image holds a black background. Many stars dot the scene, their light shining within or through the nebula.
Astronomers created this infrared mosaic of the Tarantula Nebula (Caldwell 103) using exposures from Hubble’s Advanced Camera for Surveys and...
Clouds of pink, white, brown, and grey fill the scene. Bright pinkish-white cloud fills the upper-left quadrant of the image. A few large, yellow stars and many, small white stars dot the scene.
