A new composite image of 30 Doradus—the Tarantula Nebula in the Large Magellanic Cloud—shows different parts of its turbulent environment by combining X-ray, infrared and optical observations. Blue traces hot gas, red picks out dusty filaments and young stars, and green shows hydrogen gas and scattered stars. The blended colors mark overlapping datasets, not the nebula’s literal appearance to the human eye.
What is 30 Doradus?
30 Doradus, also called the Tarantula Nebula, is a star-forming region in the Large Magellanic Cloud. A composite view described by Brooks Mendenhall for Astronomy.com on October 8, 2026 brings together observations from NASA’s Chandra X-ray Observatory, the James Webb Space Telescope (JWST) and the Hubble Space Telescope.

The image is useful because each telescope records a different range of light. Combining those observations makes structures visible that a single wavelength alone would not show.

What do the colors in the image mean?
| Displayed color and data | What it traces |
|---|---|
| Blue — Chandra X-ray | Hot gas blown off young, massive stars and heated further by stellar winds and shock waves. |
| Red — JWST infrared | Dusty filaments and points of young stars, associated with ongoing star and planet formation. |
| Green — Hubble optical | Hydrogen gas warmer than the material JWST detects in this view, along with scattered individual stars. |
These are assigned colors in a multi-wavelength composite. X-rays and infrared light are outside the range of human vision, so blue and red here identify data layers rather than show how those wavelengths would look to the naked eye.

What does the blue X-ray light show?
Chandra’s blue layer reveals clouds of hot gas associated with young, massive stars. Their winds drive material outward, while wind collisions and shock waves heat gas to X-ray-emitting temperatures. This layer therefore traces energetic gas around the stars, rather than the stars’ visible surfaces.
What do the red filaments reveal?
JWST’s infrared layer highlights dusty filaments and points of young stars. In the image’s interpretation, this dusty material is part of an environment where stars and planets are forming. The infrared view makes the dust structures legible alongside the hotter gas traced in X-rays.

What does the green Hubble layer add?
Hubble’s optical observations show hydrogen gas described as warmer than the material visible to JWST in this image, as well as scattered individual stars. Green is the composite’s assigned color for this optical layer; it is not a claim that hydrogen gas naturally appears green.
Why do some areas look orange, purple or yellow?
Where the blue, red and green datasets overlap, their colors blend into oranges, purples and yellows. Those blended regions indicate that multiple layers contribute at the same location. They should not be read as a literal visible-light color map of the entire nebula.
