活跃的M82星系多波段合成图是由3个伟大的天文台：哈勃空间望远镜，钱得拉X射线天文台和斯必泽空间望远镜共同拍摄。x射线图由钱德拉提供（蓝色），红外图是由斯必泽提供（红色），哈勃天文台所拍的氢气发射部分（橙色）和最蓝的可见光部分（黄绿色）。
Composite of multi-wavelength images of the active galaxy M82 from the three Great Observatories: Hubble Space Telescope, Chandra X-Ray Observatory, and Spitzer Space Telescope. X-ray data recorded by Chandra (courtesy of NASA/CXC/JHU/D.Strickland) appears here in blue; infrared light recorded by Spitzer (courtesy of NASA/JPL-Caltech/C. Engelbracht (University of Arizona)) appears in red; Hubble's observations (courtesy of NASA, ESA, and The Hubble Heritage Team (STScI/AURA)) of hydrogen emission appears in orange, and the bluest visible light appears in yellow-green.

可见光波段
2006.4月，NASA和ESA为庆祝哈勃空间望远镜的16周年纪念日，展示了这帐壮丽的星暴星系图片，M82。这张嵌合照片是迄今所拍M82中最清晰，视场最大的。这个星系以其蓝色的圆盘最为引人注意，网状的细屡云气和有中心区域爆炸形成的氢气柱。哈勃于2006年3越拍摄。天文学家收集了6张通过4种颜色滤光片在可见光波段和红外波段较为完好的把恒星光和来自正在成长的氢气丝的光线给拍摄下来的照片并复合到了一起
To celebrate the Hubble Space Telescope's sixteenth anniversary in April 2006, NASA and the European Space Agency (ESA), released this image of the magnificent starburst galaxy, Messier 82 (M82). This mosaic image is the sharpest wide-angle view ever obtained of M82. The galaxy is remarkable for its bright blue disk, webs of shredded clouds, and fiery-looking plumes of glowing hydrogen blasting out of its central regions. The Hubble observation was made in March 2006. Astronomers assembled this 6-image composite mosaic by combining exposures taken with four colored filters that capture starlight from visible and infrared wavelengths as well as the light from the glowing hydrogen filaments.
红外波段
这张红外波段的M82图片是来自斯必泽空间望远镜，在其一边有一个不规则星系，散发着蓝色的光。来自头顶和底部类似蝴蝶翅膀的巨大红色尘埃星云被认为其成分与汽车尾气非常相似。其难闻的物质叫做稠环芳烃，存在于地球上的排气尾管，烧烤地和发生燃烧反应的地方。在星系中，原料由恒星制造，其星风和辐射将物质吹到了外层空间里。这张图片由斯必泽在2005.5拍摄。
This infrared image from the Spitzer Space telescope shows Messier 82, an irregular-shaped galaxy positioned on its side, as a diffuse bar of blue light. Fanning out from its top and bottom like the wings of a butterfly are huge red clouds of dust believed to contain a compound similar to car exhaust. The smelly material, called polycyclic aromatic hydrocarbon, can be found on Earth in tailpipes, barbecue pits and other places where combustion reactions have occurred. In galaxies, the stuff is created by stars, whose winds and radiation blow the material out into space. The Spitzer observations for this image were taken in May 2005.
