M82 Cigar Galaxy (Webb + Hubble Fade)

NASA’s James Webb Space Telescope’s near-infrared imaging survey of Messier 82 (M82) is the most recent observation of this starburst galaxy, adding to the amount of overall data that has been collected over the years on this galaxy by different space telescopes.

The Hubble Space Telescope previously looked at M82 in visible light. The amount of dust within M82 shrouds the galaxy’s details at this wavelength. Webb’s infrared-light view pierces through the dusty environment of M82 and reveals millions of individual stars within the galaxy’s heart (seen here as luminous blue-white granules). Red-orange clumps are small dust grains.

Composite image of edge-on spiral starburst galaxy Messier 82 as observed by NASA's James Webb and Hubble space telescopes. Hourglass-shaped plumes of gas are shooting outward from above and below a bright blue-white, disk-shaped center. The plumes are yellow near the galaxyu2019s bright center, denoting areas of ionized hydrogen gas as observed by Hubble, and gradually become redder as you move farther away. Messier 82 is set against the black background of space, which has many distant galaxies that appear as small white and orange spirals, ovals, and points of light. Toward the right of Messier 82 is a blue-white star with eight-pointed diffraction spikes that are characteristic of Webb.

M82 Cigar Galaxy (Webb + Hubble)

Scientists used NASA’s James Webb Space Telescope to image edge-on starburst galaxy Messier 82 and trace its evolutionary history. This Webb and Hubble composite image includes 16.5 million stars (blue-white), dust grains (red-orange), and ionized hydrogen gas (yellow).

M82 Cigar Galaxy (NIRCam Image)

NASA’s James Webb Space Telescope observed edge-on starburst galaxy Messier 82, peering through dust to reveal 16.5 million stars and the galaxy’s distended disk structure. Scientists seek to learn the galaxy’s evolutionary history with the Webb data.

A side-by-side comparison of a portion of starburst galaxy Messier 82 (M82) as seen by NASAu2019s Hubble (left) and James Webb (right) space telescopes. The left image is labeled u201cHubbleu201d and the right image is labeled u201cWebb.u201d Hubbleu2019s visible-light view at left shows bright, bluish light radiating from the center and a thick lane of dust, black in the center and red around the edges, diagonally stretching across the scene. Thinner strands and clumps of reddish dust cover the majority of the view. Webbu2019s infrared-light view at right shows a dense area of stars, depicted as luminous blue-white grains, against the black background of space. Toward the right side is clumpy red material, which is most visible toward the top right corner.

Side-by-side comparison of a portion of starburst galaxy Messier 82 (M82) as seen by NASA’s Hubble (left) and James Webb (right) space telescopes. Hubble detailed M82’s gas and dust structure, while Webb pierced through the dust and resolved millions of stars in infrared light.

Annotated image of starburst galaxy Messier 82 captured by Webb's NIRCam (Near-Infrared Camera) instrument, with compass arrows, a scale bar, and color key for reference. Title text at top left reads u201cJames Webb Space Telescope, The Cigar Galaxy, M82.u201d Hourglass-shaped red-orange plumes of material are shooting outward from above and below a bright blue-white, disk-shaped center.

Below the image is a color key showing which of Webbu2019s NIRCam and Hubbleu2019s ACS/WFC filters were used to create the image and which visible-light color is assigned to each filter. From left to right, NIRCam filters are: F115W is blue; F200W is light blue; F335M is orange, and F444W is red. ACS/WFC filter F658N is yellow.
