Composite image of Tarantula Nebula from Chandra and Webb data released

The Large Magellanic Cloud, a Milky Way companion galaxy, has a region of active star formation known as the Tarantula Nebula (also known as 30 Doradus). This brand-new Chandra & Webb image spans around 360 light-years and combines X-ray and infrared light.

This publication includes a composite image of the Tarantula Nebula, also known as 30 Doradus, which is a region of prolific star creation in a nearby galaxy. Gas clouds in the image that are royal blue and purple interact with clouds that are red and orange. Large sparkling stars and bright specks may be seen shining through the vibrant clouds.

The X-ray data was gathered by the Chandra Observatory and may be seen as patches of royal blue and purple gas clouds. The center of the photograph is occupied by the largest, brightest blue cloud, which is about triangular in shape and looks to be rising. In the vicinity of the image's right and left margins, there are denser X-ray clouds.

The James Webb Space Telescope's infrared data is represented by the red and orange gas clouds. These blotches mimic raging fire clouds. The brightest and most noticeable infrared cloud may be seen to our upper left and is about triangular-shaped downward.

The upward-pointing bright blue triangle in the image's center is surrounded by wispy white clouds. A bright star with six long, thin diffraction spikes is visible inside this frame. A group of smaller, brighter specks may be seen next to it, illuminating the nebula's newborn stars.

The Milky Way is a member of the Local Group of galaxies, which also includes the greatest and brightest region of star creation, known as 30 Doradus (or, informally, the Tarantula Nebula). Astronomers have long studied the star 30 Doradus, which is situated in the Small Magellanic Cloud, a galaxy close to the Milky Way, in order to learn more about the birth and evolution of stars like the Sun.

Over the course of the project, 30 Doradus has been often observed by NASA's Chandra X-ray Observatory, frequently under the guidance of Dr. Leisa Townsley, who passed away in the summer of 2022. Scientists will have the chance to learn more about star formation and its associated processes both now and in the future as these data will continue to be gathered and examined.

The infrared image from NASA's James Webb Space Telescope and the X-ray data from Chandra observations of 30 Doradus are combined in this new composite image. The X-rays (royal blue and purple) show gas that has been heated to millions of degrees by shock waves produced by the winds from huge stars, which are similar to the sonic booms from jets. The Chandra data also pinpoint the remnants of supernova explosions, which ultimately launch vital substances like oxygen and carbon into space where they become a component of the following generation of stars.

The amazing canvases of colder gas that serve as the building blocks for future stars can be seen in the infrared data from JWST (red, orange, green, and light blue). The JWST's perspective also shows "protostars," or young stars that have just started to ignite their stellar engines. Unlike the majority of the Milky Way's nebulas, 30 Doradus has a unique chemical makeup. Instead, it is a representation of the galaxy's environment a few billion years ago, when stars were developing considerably more quickly than is apparent to astronomers now. This gives researchers the chance to learn more about how stars developed in our galaxy in the past thanks to 30 Doradus's relative proximity, brightness, and this.
